Thanks YC, Danny, Robin, Thanks your suggestion. One more question, my FM receiver (Futaba) has 6+B channel. I have two Servos, a 3 in 1 mixer and a ON/OFF switch. I think the ON/OFF switch is plugged into the 'B' channel. But where the two servos and mixer (with two plugs) plugged into the receiver? I am now setting up my new 'Bee', and now wondering what color pattern for the wing. See you soon.

尋日我同阿邦去屏風山﹐睇下有無適合放滑翔機既地方。我地由大尾篤出發﹐行上 511m 高既仙姑峰﹐用左大約一個鐘。我到依家至知阿邦原來係行山專家﹐體能仲非常之勁。上仙姑峰個段路都幾斜,沿途我停左最小三次﹐氣喘如牛﹐但阿邦竟然臉不改容﹐真係要寫個服字﹗由仙姑峰沿衛奕信徑往西行﹐有唔少適合飛北風或南風既位﹐但最正既係要算係黃嶺。呢度向北既斜坡比較平坦﹐但升力幾好﹐雖然我地去到個陣只係有小小風﹐我隻 Mini Corado 都可以落4粒鉛黎飛。由於個斜坡又闊有無石﹐落大機都肯定無問題。向南個邊既斜坡就斜好多﹐最斜個位估計有成 70 度。呢個斜坡係我見過之中最靚既一個﹐斜坡面非常平滑﹐均勻地鋪滿及膝既短草﹐好少樹。谷底有個樹林﹐樹林同草地既分界線好清晰﹐睇落好似經過人工修飾既哥爾夫球場一樣。呢面斜坡對著既係一個盤地﹐四面環山﹐可以想像係無風及陽光充沛既日子﹐係谷底產生既熱氣沿山坡上升並匯聚成龐大既熱氣團﹐玩 thermal 肯定開心到暈。呢度飛行空間極闊落﹐南北斜坡既分界線只有一條路咁窄﹐加上向南既斜坡好斜﹐後山既亂流層應該好簿。用大機玩 DS 肯定一流﹗可惜尋日既風力麻嘛﹐兼且要望著太陽飛﹐我D左幾個圈就無繼續。尋日我地基本上係行山多過放機﹐幾乎連續行左成六個鐘﹐以前我肯定唔掂﹐但尋日我竟然頂得順﹐體能明顯好過以前﹐相信同我平時執機多好有關係﹐模型滑翔機真係一項好健康既活動黎嫁﹗呢度有幾張尋日影既相﹐大家有興趣可以睇下 http://www.geocities.com/yclui_hk/Piing_fung_shan_1.html

Hi, i remember being like you, too many questions, too many answers :?) I think you should use normal duracell batteies for your Bee reciever (& controller if you like), reason is when you go flying just carry 4 spare AA batteries & you will never have to worry about charging or going flat at the field. I found it important for a beginner (like me) to learn how to fly more than learn how to play with batteries & stuff!! Just take your plane to the field mentioned below on the weekend & everyone their will be happy to help you set it up.........THEN THROW IT..........forget about everything else. Once someone has helped you set it up correctly just keep flying it, you will learn all you need to know by your mistakes & the comments/answers from others who are their. Please do'nt go flying alone if you never flown before or never been their before, otherwise you will go home very dissapointed, tired, dirty & cold! Go with a friend, you'll have so much fun & probaly learn something. PS......BRING A CHEAP PAIR OF BBQ GLOVES..........TRUST ME!!!!

Congradulation for joining the soaring world!! About your cases: 1) It's up to you whether using rechargable or normal battery. Just that with rechargable batt, you could cover it nicely. 2) Wing Master 3in1 is a mixer, beeper and voltage monitor. It's mixing function let you use standard, non-computerized transmitter to mix both aileron (or elevon for flying wings) to move simultaneous according to your stick input i.e. when you pull up, both elevon go up; when you pull left, left elevon goes up and right elevon goes down. 3) If you have the 3-in-1, you need not buy a separate beeper!! Anyway, a beeper can be plugged into any channel, and the channel can still be used bcoz the beeper also as output pin relaying the Rx's signal. Go go go, fly you bee high and enjoy!!!!!!!!

I shall keep my weapon secret until it can really blast up so I won't loose face! After reading the information on Sanyo battery, I think 1100mAH KR1100AEL NiCd battery is perfect for this competition as it has very low internal resistance, ie, 9 mOhn, that means it can deliver a current of 30A in 8.4V! I also read that new NiMH batttery can achieve the performance of NiCd with twice the capacity, some AA size NiMH batteries now have internal resistance as low as 20 mOhm, that means 20A in 8.4V, good enough! So I am still puzzling on what battery should buy, 1100mAH for NiCd or 1700mAH for NiMH?

Hi Stanley, you may visit this web site http://sanyo.wslogic.com which provides tables comparing the capacity, weight, dimension and internal resistance of all SANYO Ni-Cd, Ni-MH and Lithium batteries. Among all 1700 mAH Ni-Cd cells , the RC-1700 is likely to be the best for our application. I guess RC in the model number means Radio Control. My own choice is KR-600AE which is light and has a low internal resistance.

Stanley, When you buy the batteries, please do not only consider the Capacity, you need to consider the Battery diameter too. A cell with diameter close to AA battery can only use for 380 motor (the motor used in Little White). If you use a 540 or 550 motor, you need to use a bigger diameter battery, say C cell diameter. The length of the cell will have relation to the Capacity, the diameter will have relationship to the Internal resistance. So with the same capacity, bigger diameter always work better. This phenomenon is always true.

Stanley, If you plan to buy a charger, you better buy a charger that can charge lithium batteries(7.4 & 11.1 volt), NiCd and NiMh. For sport gliders, you can use the Nicd or NiMh battery, for light weight gliders, you can use Lithium cells as they have light weight and high capacity. Cost of the Charger will variy from 300 to 1500, depends on its function. Remember to buy the chager that can use both 12 Volt DC and 220V AC as the source. Jet Hobby has a lot of chargers and motors, you can go there to try the membership 10% discount.

Mak, I have the same problem. My 2 sons want to joint and I also want to joint. The main purpose of the rule is to have the contestant design their own plane and use the plane and their control skill to win. If you do not want to make another plane for your son, one way to solve the problem is you and your son joint the contest as one contestant place. So you play one round and your son play another round. If you+your son win, both of you will share the Trophy. You can use Trainer cable too. This will be safe and all party happy.

I have some hints for you guy to get better scores in the contest: 1) Add a small wire or wheel on the rudder and use it to give some control to the sliding path after landing. Without that, it will be difficult to make the plane stop on the expected point. 2) Use NiCd or High Volt Ni-Mh battery, Nicd voltage is 1.2v, NiMh is 1.1~, MiMh HV is close to 1.2V 3) If you are not using Brushless motor, remember to add 3 capacitors onto the motor. Connecting way is: a 0.1u over "+" terminal and Housing; a 0.1u over "-" terminal and Housing; a 0.047u over "+" termainal and "-" termainal. 4) Do not put the antenna and receiver too close to the motor to avoid electric noise. 5) Remember to add BB if you plan to use the hill slope lift a lot. 6) If you plan to get a higer score by hard spot handing, remember not to put the motor at the plane nose. This will bend the motor shaft very easy. 7) Cobalt motor is another alternative if you do not want to buy the expensive Brushless motor. 8) Remember to give air vent for motor cooling. 9) If anyone can design a plane with folding wings, that will be great because it will reduce a lot of air friction. In the first 40 sec motor stage, small air friction will help the plane fly faster and it can go to a higher point. But the design work is not easy.

Hi Stanley, I am afraid Motocalc is a must if you want to work out a combo that will match your plane with good confidence. The way I did it was as follows : 1) Launch Motocalc. 2) Enter the parameters of the plane, i.e. airfoil, wing area, weight . 3) Enter battery info ( 7-cell Ni-Cd or Ni-MH in our case ) 4) Select a motor that looks right 5) Specify the range of gear ratios and prop sizes to be tested. 6) Compute results. 7) Look at the rate of climb, current drawn and flight duration. 8) Pick a combo that provides a high rate of climb, pulls a current that is within the ratings of the motor and the battery ( 20C for Ni-Cd ? ) and gives sufficient flight time ( 1.5 to 2 min. ? ). 9) Check if there are any rooms for weight reduction such as using a lighter motor or battery of lower capacity. 10) Loop until satisfied. The current drawn by my combo will be about 16 Amp when static and gradually reduce to about 11 Amp after the plane has built up speed . It may sounds like solving a multi-dimensional optimization problem but the process is actually quicker and easier than what you may imagine. Give it a try. Its an interesting learning process.

Hi Mak, most Hacker motors have two versions : motor-only and motor+gear box . Cyberheli (冠升) at Mongkok just carries the motor-only version so I did not get my Hacker from them but this vendor in Japan http://www.aircraft-world.com/^motors.asp . As space is not an issue on your Bee, I would recommend you to try this out-runner brushless motor : http://www.aircraft-world.com/proddetail.asp?prod=AM-AXI-2808-20&from=14 . It is light ( 79 g ) , less expensive than the Hacker (US$ 84. 5) and able to drive a 10-inch prop without the need of a gear box. If you want to go for brushed motors, you may talk to 阿堅 and see what 偉高 has got. They are carrying the full line of GWS products.

Hi Stanley, my motor is rated 2300rpm per volt. This is considered a low kv motor and is supposed to be used in low current high voltage applications. It is intented to be used with my LiPo cells but . . . Nevertheless, I don't want to buy another motor as they eat money. To use it in 7 - cell / low rpm, I have to go for a large prop diameter for better prop effeciency. This is where the 15 inch come from. My system now draw about 17A and turning the prop at about 3500rpm (low speed, but enough to pull the plane straight up from the hand!) Prop pitch is another story. If your plane flies fast, you need a large pitch. Otherwise the prop "cannot keep up with the plane". For our sailplanes the flying speed is slow and a prop with large pitch will stall (like a wing at high angle of attack), making it less efficient. Find some spare time and have a try on the motocalc. It worths!

Hi Stanley, let me try to answer some of your questions. larger and higher pitch propellers takes more energy to drive, so that the motor will consume more Amp for a large propeller than a smaller one. If the propeller is too large, eletric current from the battery can cause the motor to burn.Brushed motors at the same size have a smaller max current capacity than bruchless motors, that one area where brushless motors are better. These information comes from somewhere in internet, I forgot where! so, tell me if I'm wrong.

Hi Mak, Good observation ! thats why I didnt consider Kontronik as they are too heavy and bulky for my Highlight. Brushed motors are perfectly fine provided that the set up is right. In fact my original plan was to use brushed motors but the space is just too tight in my Highlight so I finally dropped the idea and went for a slim brushless. For your Bee, you may consider the 400-class power package made by GWS. http://www.aircraft-world.com/prod_datasheets/gws/powersystem/eps400c.htm but it will be difficult to find the optimal set up with Motocalc as GWS does not provide the required data such as motor constant and winding resistance. Regarding the choice of batteries, I am still in the process of learning about them but one thing I am sure is that bigger does NOT necessarily mean more power. For example, you can get this SANYO 1100 mAH Ni-Cd http://sanyo.wslogic.com/pdf/pdf/KR-1100AAU.pdf and this SANYO 600 mAH Ni-Cd http://sanyo.wslogic.com/pdf/pdfs/KR-600AE.pdf at Ap Liu Street and if you compare their internal resistance, you will find that the resistance of the bigger cell is much higher. That means the smaller cell is actually more capable of delivering large currents while the bigger cell is more suitable for low-current, long-duration applications. I am using it in the receiver pack of my Elita. Hope it helps.

I visited the Kontronic website to check for details on brushless motors. I found the smallest motor Kontronic FUN 400-23 to be 110g with cables.( and they are very expensive,can buy a good sailplane for that price!) I weighted the motor that comes with the Electric Bee, it reads 72g only. That mean if I use brushless motor, I'll have more power, but will add more weight to the plane! The case is, if it's like YC's calculations, 40 seconds can get the plane to a hight of 300m with a brushless motor, then that will be a waste for me. Like what Stanley said, I'll not be able to see my Bee at that hight. Even if I can see it, I'll not be able to control it as well as at, say 100m. YC will have no problem with this, for he have his hat-mounted binoculars! Anyone who tried the original eletric Bee's setup, please tell me rather it can bring the plane to a hight of around 100m ? That's all I want. I prefer to have a lighter and smooth plane. to make it smooth, I need propellers that folds up to the back-side like a tail when not in opperation mode. Tsz Ming, do you have one that fits the Bee! The standard propeller will act like an air-break when the motor's turned off. About the batteries, If I use smaller capacity batteries, will it be less powerful than a higher capacity one? I know at the same voltage, power output should be the same, but will smaller batteries can not support the standard motor's Amp requirement? I want to use 350mAh NiCad, and get it recharged during the contest. Anything I missed!

I placed my order just yesterday from a vendor in Japan http://www.aircraft-world.com/^motors.asp who has been offering good service, good price and VERY cheap shipping ( US$2.5 flat to anywhere in the world ). I chose the Hacker B20-L15 because it is light ( 69 grams with the gear box ) and slim ( 20 mm in diameter ) enough to fit into the nose of my Highlight. If you have enough room in your Trendy, I would recommend brushless out-runners mentioned by Robin. They are cheaper and more efficient ( no gear box needed for driving big props ). Cheers.

Look like I need to catch up with you guys in the current electric mood. I have looked at the Hacker brushless motor site, it seems that the prize for a motor + controller set may go up to at least US$600, too expansive for me! I also looked at the Kontronic site at http://www.kontronic.com/fundsete.htm they do not have the prize list for their DIRVE 501 set which I think is suitable for my secret weapon. I wonder how much does it cost and can I get it from Tat Cheong Model. Hi Mak if you are going to Tat Cheong to buy the motor, let me know, I need your help.

Hi Mak, I am just as inexperienced as you are when it comes to electric. I got my first brushless motor , a Hacker B20S for my indoor electric helicopter just last week. The motors is SOOOOO. Quiet when running that I really cant feel its power. OK, 12x6 means that the diameter of the prop is 12 inches and its pitch is 6 inches. 12-inch prop is too large for the Bee ? visually yes but aerodynamically I am not sure, 1.6 meter F5B ships are using props as large as 15x14 ! You can get Kontronik motors from Tak Cheong and Hacker motors from Cyberheli but the latter carries motors only, no gear box.

Hi YC, I tried MotoCalc, it gave me a list of motor,battery and propeller to use, such as Plettenberg HP 300/20/A3 S + 6x1700SCR +12x6 Prop.! I've never used any brushless moter before, and don't know what size is the 12x6 Prop. Does it mean 12inch or 6 inch? 12 inch will be much too large for the Bee. There's no time for me to search for them from aboard. Are there any local shops that stocks suitable bushless system for light weight sailplanes? If so, which manufacturer's goods do they stock? MotoCal does allow selection of which manufacturers' motors to use.

Hi Robin, you may well be right. I have never done this before so anything can happen ranging from winning the contest or frying the motor, speed control or both. Regarding the prop, it will be a folding prop so the drag will be more or less independent of the prop size. My model in it's original form is light and designed for thermalling but for some reason, it doesn't glide very well. If it still doesn't perform with the assistance of an electric motor, I will bring it to a spectacular end in the air combat next year.

I think to achieve a 10 minute thermal duration is a daunting task. Remember from last HLG contest, the longest duration is about 2 minutes 30 seconds after a bungee launch to a height of about 50m. In average most people did this in 1ess than one minute. Also, the glider does not have the load of motor and battery to bear. Well, after re-thinking, I would agree that the best strategy is to shoot up the plane as high as possible because the chance to find a thermal is higher. That means faster plane will also be in advantage in seeking the thermals - how about converting the MIniNYX or MiniCorado...

I think one of the purposes of the competition is to test the pilot's abitily to find and utilize thermal to keep the glider airborne. So it should not be a simple math of Time = Height / Sinking rate. Otherwise our gliders will be no difference to a parachute!

Hi Stanley, I am afraid I don't have an answer to that until we see how different setups perform in the forthcoming contest. Thats part of the fun isnt it ? There is no doubt that lighter planes perform better in thermals but going for smaller planes may not be such a good idea. For example, the popular electric plane小白 is very light, it goes quite fast with a small and simple power package ( no gear box ) but I dont think it will glide very well due to the low Reynolds number of its wing. This is in line with Maks experience on his 1m span Colibri HLG which does not perform very well in light lift so I believe 1.5m is more or less the minimum wing span for planes to be competitive in the upcoming contest. Regarding the choice of power package, the relationship between weight and power goes against the intuition of many people. For example, I can save about 30g by replacing the 600 mAH Ni-Cd pack with 350 mAH Ni-MH but due to the higher internal resistance of the latter, the output current and hence power will be significantly lower. The consequent loss of height will probably out-weight the gain in L/D ratio. Depending on the current taken by the motor, using 350 mAH Ni-MH will bring the risk of battery running out before the completion of the flight as the capacity is reduced by nearly half. My decision is therefore to take the weight penalty. Again, these are purely theories and I cant wait to see how things go in reality. Cheers.

Y.C., what do you expect the sinking rate of your 550g Highlight? If it is 0.5m/s, then you end up with about 10 minutes of soaring time at an initial height of 300m. So it may a good approach to shoot up at 300m - but again I don't think you can see it and control it properly. If I rather use a very light thermal soarer with 0.2m/s sinking rate and initial shoot up at, say 120, I end up with about 10 minute duration. So the tradeoff is lower sinking rate vs higher inital shoot up. In considering other factors, I still think a small light thermal model will be in advantage. Any comment?

I am hoping that the power will make up for the Highlights poor gliding performance . Motocalc says that the rate of climb achievable with the mentioned configuration will be about 6 meters per second. I am also planning to try 12x7 prop ( yes, that's really BIG ! ) which is supposed to be able to pull the plane up at a rate of 8 meters per seconds . With 40 secs of motor time, I should be able to send the plane up to more than 300 meters !

Hi, I am really thinking of converting the FVK Trendy to electric for the forcoming electric glider duration and spot landing competition. But .... is it a good approach? Trendy is about 72", it seems a bit too big and the motor and battery will add up lot of weight to reduce its thermal soaring capability. So what is the best formula for this kind competition? Which one of the following should be used? 1. A small but very light foamie plane, say less than 30". Also try to minimize the weight of on-board electronic and main battery. The battery should be small, say 300mAH, but just good enough to release all power in 40s duration. 2. A big plane, definitely not foamie, with sufficient wing span to carry the loading of heavy-duty battery and motor and still be able to soar arround for sometimes. Apart from these, big plane may be easier to land (or not!) Any suggestion and comment?

I only order the lowest cost version (D-Box-balsa), the cost including shipment should be around HK$5,200 according to the current Euro-HK$ exchange rate (1-9.2).

This is according to the regional weather info on the "underground" weather website. Waglan Island (near Shek O and Clearwater Bay) tends to have the most consistent wind direction and the strongest easterly wind. This perhaps explains why these sites are the best for easterly wind. In contrast, Sai Kung (just below 昂平) and HKUST (confusingly referred to as Clearwater Bay on the said weather website) have more variable wind direction (often changing radically in the course of a day) and weaker easterly wind strength, hence these sites are less attractive for sailplane modellers.

Hi, K. Y. Mak & Y. C. Liu... Regarding your recent frequency jam or disorder, I believe it is due to the high tension cables closed to the Jetson Road junction. It is quite unsafe to fly there with 72Hz. I also fly 72 Hz myself. I have sent a frequency glitch electronic device closed to these cables and found that my receiver received lots of glitches when flying close to them. (A frequency glitch device is a small electronic device which is plugged into a spare receiver socket. There is a small indicating light on it. On landing, according to the behaviour of the indicating lights, we can tell how many times the receiver has encountered frequency disorder.)I also found this happened ever since the high tension cables were erected. However, this only happens momentarily, but scarry. Happy Landing to you all.

jam機既原因真係多到數唔清﹐我通常jam機都搵到元凶﹐好少試過阿麥講既情況。最近我轉左用合法頻72MHz﹐係扎山道個位就試過一次﹐維持只有幾秒。落機後係地面 check range 完全無問題。當初我仲以為 72MHz真係好多人講咁唔掂。跟?我繼續飛﹐點知問題又黎﹐但今次我肯定唔係干擾﹐而係個接收機收唔到訊號﹐因為無控個刻﹐我聽到隻機個BB響﹗確實原因我到依家都唔知﹐因為同樣既問題再無發生過。我既推測係由於當時隻機後面(即扎山道個位既左邊) 係一排又高又闊既山坡﹐電波俾排山坡反射到隻機個度﹐同由發射機直接射到隻機既電波既相角相差 180度﹐結果反射波與直射波互相抵消﹐形成局部空間出現一個訊號黑洞。但呢種黑洞既範圍理論上應該好細﹐阿麥遇到個種 jam機肯定唔係呢種原因造成。servo線太長係唔係會導致失控我都唔敢肯定﹐網上有D人講到好誇張﹐話一定要扭埋D線﹐繞磁環甚至要用光纖代替銅線云云﹐我自己就試過將servo線延長8呎並且無扭埋D線﹐但個 servo 完全無震﹐擺把轉起上黎好嘈同埋個摩打入面好多火花既電鑽埋條servo線個度一樣無事。所以我D大機既 servo線除左扭埋之外就也都無做﹐未試過有問題﹐不過我唔係飛好多﹐所以不能作參考。其他師兄可否講下佢地D方面既經驗

Hi, Robin, .. A 10Amp battery will last longer than a 7Amp battery since they have the same voltage. In your case, you are using a 7/500 battery pack which is only 8.4 volt. Instead of investing on a car in order to field charge your 7/500 pack, it is better to invest a few 7/500 packs and charge them at home. You may use your transmitter charger to power your 7/500 pack easily. There is no point of buying a heavy 12V battery and carry it to the field. You have to recharge the 12V battery somehow later. (I take the assumption that 7/500 means seven pieces of 1.2 volt 500 mAampHours batteries connected in series.)

Hi Robin, It is really difficult to say whether adding a cell or two is a benefit or not. On one hand you got a higher peak power. On the other hand the plane is heavier that it needs more power to fly. Using high capacity cell is not necessary fly longer either, as the high capacity cells are usually heavier. Some high capacity cells have the same size and weight as the low capacity type but these cells usually have a larger internal resistance, which is not suitable for use in high current applications. Do you know a program called "MotoCalc". You enter the config of your plane and power system and it can predict the performance. You can play with different cells, motors, props, gears, whatever.

Thanks for your advice, YC and Yeung. I did not have much experience in using the LiPo, lets see if the followings are correct: Assume 7-cell NiCd can output 336W max. to the load, then if we change to LiPo that is 3.8V/cell and maximum discharge current of 6C, the "equivalent" cell count will be 336/3.8/6 = 14.7 AH*cell. For 2000mAH cell the cell count is then 14.7/2 = 7.35 cells. So 6 cell 2000mAH LiPo should be within the 7 cell NiCd limitation. -------- Ah, YC, the long running time of using LiPo is a great advantage as a single charge can provide a whole day of fun. No need to bring a heavy gel cell to Sham Chung - a good reason for choosing LiPo!

Hi CM, the shortfall of dischaging character of LiPolymer cells can be solved by connecting the cells in parallel. Say 2s-3P configuration, that is with 6 LiPolymer (6C type) cells of 3.7v 1200mah each, you can get 7.4v (2s) and 3x1200x6C (3p)=21.6A disharging current. This is what the Japanese and American doing to get the discharge current of a standard 540 motor. This boosts the game to be very costly.

Hi Ken, About point 3, that model size is free but cell count is limited. I have some comments on the maximum lithium cells used. Lithium cells cannot discharge as much as NiCd or NiMH, and so it needs to use high voltage / low current to attain the same output power. For example, NiCd can easily discharge at 40A+. At 7 cells the power input to the controller/motor is 336W. Typical LiPo (3.8V) cells can discharge at 6C. For 2000mAH 2-series cell the max power it can output to the drive is only 91.2W. And so using only cell voltage as the guildline is not the best method.

近半個月收很多不同意?,在消化後作出少許修正,若各師兄師弟?有重大反對,可將賽例暫定如下: >>>1. 參賽穸眸極H自己之電機作賽,不能借機出賽。<<<// >>>2. 每場比賽最多四位參賽穻P時出機,每場比賽用十分鐘時間。最初40秒參賽穸i以開動馬達令飛機盡量扒升。40秒後不能再開馬達,只能以山坡風及熱氣流將飛機保持高度。在最後一分鐘評判用訊號通知名各機師降落,同時開始倒數。降落點為在平地上四個不同位置之圓點,各機師需降落近其指定之一個降落點。降落點會盡量安排到飛機不容易相撞。<<<// >>>3. 比賽用之飛機沒有任何尺寸限制。大機或細機圴可參加。但飛機最多祗能用7NiMh NiCd電池。 若用鋰電,則不可多過兩節,即電壓不能高過7.4 Volt。同時每位參賽者只能以一隻飛機參賽。<<<// >>>4. 計分方法以飛行時間 + 降落點得分計算。每場最低分為0分,最高分為20分。不會有負分數。<<<// >>>5. 飛行時間為起飛至飛機停定之時間。若飛行時間多過十分鐘,得分將會倒扣。例如飛行9.78分鐘,得分將會是9.78分;如飛行時間為10.61分鐘,得分會是(10-0.61)=9.39; 例如飛行4.35分鐘,得分將會是4.35分。如此類推。<<<// >>>6 .降落點得分之計算方法為量度降落點與飛機停定後之機鼻之距離。5-4米得1分;4-3 米得2分;3-2米得3分;2-1 米得4分。如距離為0-1米,可得5, 若距離在1呎內,會另加額外5,即共得10 分。<<<// >>>7. 無論任何原因飛機不能正常地滑行降落,計分方法仍然如上<<<// >>>8. 若飛機在空中有零件跌出,不論故意與否,均會扣5分。<<<// >>>9. 若在40秒之後再次開動馬達, 每秒扣2分。由評判裁定馬達開動之秒數,不足一秒亦作一秒計。 >>>9. 每位賽員在正常情況下,可有5次出賽機會,以各場得分之和計算總得分。但大會可因參賽人數而貝w各人之出賽次數。<<<//

美國有D模型滑翔機會 http://www.soarabq.org/f5j_wc_2003/f5j_main.htm 搞既比賽所用既例係F5B既簡化版﹐叫F5J. 同阿Ken早前提議既賽例差唔多. 我地不妨參考下。 F5J由於唔係好流行﹐所以仲未列入FAI既官方賽例 http://www.fai.org/aeromodelling/documents/sc4.asp 。其實係會既層次搞比賽最緊要係好玩﹐個個人都有機會贏﹐係唔係跟國際例未必太重要。大陸一向都唔跟足FAI例﹐佢地將FAI例簡化﹐訂出一套對技術要求較低既賽例。套例用P字行頭﹐譬如P3A即係F3A既簡化版﹐上次我地係珠海雷達行廠房外面見到既動力機花式賽就係P3AP代表 Pu Tong, 即“普通”之意。

滑翔機會計劃在十二月於深涌舉行電動滑翔機比賽。賽例還未有定下來,過去數星期我一直在搜集資料。希望定出一套較F5B簡單,需較少工作人員及偏重控制技術之較量。我有以下建議,各機友若有任何意見,歡迎提出參考。下面各點只作參考,並非正式賽例。 1.>>參賽穸眸極H自己之電機作賽,不能借機出賽。 2.>>每場比賽最多四位參賽穻P時出機,每場比賽用十分鐘時間,第一分鐘可以開馬達令飛機盡量扒升。一分鐘後不能再開馬達,只能以山坡風及熱氣流將飛機保持高度。在最後一分鐘評判用訊號通知名各機師降落,同時開始倒數。降落點為在平地上四個不同位置之圓點,各機師需降落近其指定之一個降落點。降落點會盡量安排到飛機不容易相撞。 3.>>比賽用之飛機沒有任何限制。大機或細機圴可參加。但每位參賽者只能以一隻飛機參賽。 4.>>計分方法以飛行時間 + 降落點得分計算。 5.>>飛行時間為起飛至飛機停定之時間。若飛行時間多過十分鐘,得分將會倒扣。例如飛行9.78分鐘,得分將會是9.78分;如飛行時間為10.61分鐘,得分會是(10-0.61)=9.39; 例如飛行4.35分鐘,得分將會是4.35分。如此類推。 6.>>降落點之得分計算方法為量度降落點與機鼻之距離。5-4米得1分;4-3 米得2分;3-2米得3分;2-1 呎得4分。如距離為0-1米,可得5, 另加額外5,即共得10 分。 7.>>無論任何原因飛機不能正常降落,計分方法仍然如上。 8.>>每位賽員在正常情況下,可有5次出賽機會。但大會可因參賽人數而貝w各人之出賽次數。 完

Time: 07:58:40

Message

根據FAI分類﹐電動滑翔機屬F5B類別。詳細賽例見於 http://www.fai.org/aeromodelling/documents/sc4.asp (下載檔案﹕ DOWNLOAD SECTION 4 FROM THE WEB: RC Electric Powered Competitions ( F5 )) F5B比賽由三項任務組成﹕距離﹐留空時間及定點著陸。比賽場地的布局類似F3F﹐有A點及B點﹐中間相距150m, 各有裁判站崗﹐場地不能有山坡或wave上升氣流。各項比賽任務簡述如下﹕起飛後的第一項任務是距離﹐作業時間200秒﹐機師需像飛F3F般在A點與B點之間往返飛行﹐盡量在200秒內完成最多圈數。過程中機師可任意啟動馬達但馬達運行時所飛的圈數將不算在總分內。完成這任務後留空環節便隨即開始﹐作業時間600, 機師需在過程中盡量把馬達運行的時間減到最少﹐過程中馬達運行的累積時間越長﹐分數便越低。比賽以定點著陸作終結﹐著陸點距離目標點越近﹐分數便越高。F5B賽例對飛機動力系統的性能要求頗高﹐動力強勁的賽機能在短短數秒內垂直爬升數百呎﹐然後再滑翔。滑翔機協會將於12月在深涌舉辦一場電動滑翔機比賽﹐為了盡量令大部份機友能參加﹐可能需要對賽例作適當修改或簡化﹐大家可否就此提些意見﹖

天文台呢次預測都算失準﹐又話5級東北風﹐結果係34級北風. 星期六在飛鵝山東風位既升力好唔穩定﹐不過都勉強飛到﹐星期日就淨係北風位有得飛下。北風位空間較狹窄﹐麻麻地好飛。阿麥就索性用隻 mini NYX 淨玩 landing﹐師傅粱不斷在旁教路﹐到走個陣阿麥已經 land 得好掂, 幾乎次次都可以 soft touch。阿Ken既兩位小朋友亦在場練習飛行但阿Ken則大部份時間練習執機。我依家至發覺北風位既日落景色原來好靚﹐望向針山個邊﹐由遠至近﹐一層一層既山脈襯托著被落日染成橙紅色既天空﹐如果當中再加上一個手操發射既機師及滑翔機剪影就係一幅靚到絕既沙龍. Lomcovak既網頁睇過好多以F3F/F3B為主題既靚相﹐估唔到香港都可以搵到拍得著既景色。

咁就真係要計下數﹐由一點飛往另一點﹐假設兩點之間無上升或下降氣流﹐整個航程所損失既高度可以用以下簡單公式計算﹕ 如 Gliding Ratio = R , 飛機相對空氣速度 = Va , 迎機頭風速 = Vh , 距離 = d . 則下沉速度 Vs = Va / R , 地面速度 Vg = Va Vh , 飛行時間 T = d / Vg , 航程高度損失 = Vs*T . 假設 Gliding Ratio = 15, 飛機相對空氣速度 = 50 km/hr, 迎機頭風速 = 16 km/hr, 距離= 3.75 km (即柴灣柏架山到鯉魚門炮台山或將軍澳工業村既距離), 航程高度損失會係 371m . 柏架山高 518m, 炮台山高 221m, 相差 297m, 即係話在柏架山機師要將飛機爬升至高于山頂 371 297 = 74m, 然後直飛炮台山﹐理論上 6 40秒後就飛抵目的地﹐到達時飛機高度應該剛剛好係炮台山山頂。如目的地係將軍澳工業村既話﹐就完全唔駛預先爬升。不過呢D都係紙上談兵﹐依家我地越野飛行面對最大既難題係視線範圍不足﹐明天如果天色好既話不如再試下可以飛到幾遠好唔好﹖上星期六師傅粱在飛鵝山東風位就試過將一隻 1.5m Mini Corado 飛到一粒” 色“咁遠仲可以飛返黎﹐由於飛機已飛越東洋山﹐我估計距離有800m。按比例計﹐如將飛機翼展加倍( 3m )﹐ 師傅粱既肉眼控機範圍就有 1.6km ! 當然發射機可唔可以去到咁遠又係另一個問題。

我覺得今次試飛失敗主要是抓不出交按時飛機的正確位置和用望遠鏡飛行的潛在危險。其實當天我把飛機飛到差不多接近你們的位置,相信起碼離開我們有700多公尺,但奇怪我不明白為什麼你們還抓不到飛機,可能Y.C.用望遠鏡尋抓更加困難。我相信如果使用強力閃燈再約定在兩點直視線上範圍尋抓,在1.2公里距離(600公尺)下不用望遠鏡也應該沒有什麼大問題。所以如果我們能選擇適當的交接點,這次壯舉應該可行。失敗乃成功之毋,繼續努力吧!

YC, 上次失敗我覺得主要是我們太難從Stanley那面找到正確的飛機。從慈雲山看去飛鵝山,Stanley所處之山艀酗茼h飛機,我們根本不能鎖定哪一只才是正確的。我認為機前和機翼兩端之閃燈是必須的。我會將上次你造之閃燈加以改良,下一次試飛一定會成功的。這個星期六你一定是忙於試驗你和CM 設計的信號系統,我們下星期六再試飛吧。1.2公里還未是我們計劃飛行中之最大山谷間距,但我已經覺得是我肉眼視線之極限,若我們不能在中途加一個站點,我提議開一個武林大會,選出兩個眼力最好的機師,在那最闊山谷兩邊把關。

YC, 如果你有留意的話,一般的天文望遠鏡上都附有一隻較小的望遠鏡,那叫做尋星鏡(finder scope), 尋星鏡倍率低,但因此視野廣,能看到較大遍的星空,它被調至與主鏡平衡,用作瞄準。同樣道理,能不能把你那個雙筒的其中之一改作finder?把左邊鏡筒整個折掉,換上準星/準門,左眼瞄準,飛機便出現在右眼的望遠鏡中,左眼因直接觀看,亦可避免飛錯航道。當然,這方法最大的缺點就是同時只能用一隻眼睛飛行,單眼飛行是否可行乃未知,但雙眼一定會十分疲倦。小小意見,望能有所幫助。

1) Plane must be a red see-through one, this benefit for plane soring under sun light, what you see is an clear transparent objet gliding overhead, it is no need to explain why use a red wing. 2) never use a powered plane, use a dihedral instead, dihedral gives better lift and a good shape for eyes catching. 3) no need to say, the bigger plane is the best choice, you can imagine a clear image of red see-through plane like a red bubble gliding overhead even at extremely high position. maybe, all of these are useless, just want you guys have good success, happy soaring.

以下是一位外國機友給我的“貼士”。我們計劃中的接力式越野飛行可能是世界首創。 Your glide ratio estimate is in the ballpark. If it's 13:1 or 16:1 makes little difference. More important is the L/D at the higher speed range. Even that is of secondary importance. My 14 foot Wilie , E-374 polyhedral, rudder elev only (11 pounds) will easily outrun my car. More important is the lift conditions. Without that, even the best L/D will get you nowhere. You want some nice open roads (not much traffic) going though lift producing terrain with plenty of places to land (the road itself makes a fine runway if there isn't much traffic). Pick a good (unstable) day, get high and stay high. Have a good vario (TE compensated if you can). This is the single most important piece of equipment you can have on an X/C plane. The plane should be as big as possible and easy to fly (i.e. should fly hands off). It should be relatively nose heavy so that it will trim to certain speeds and hold that speed on it's own (you should know what elevator trim positions corrospond to slow thermalling speeds, slow-max L/D- cruise, and fast cruise. Control throws should be reduced to that it should take effort to get the plane in an unusual attitude. You can always use high rates (dual rate switch) for landing. Have a spotter with good eyes.

上星期六我們成功把阿Ken2米電動滑翔機由飛鵝山東風位飛往650米外的東洋山(近基維爾營的一山丘)。昨天我們繼續實驗﹐嘗試把距離增加﹐由飛鵝山西南風位平台飛往慈雲山腰。我用GPS測量出來的距離是1.2公里。Stanley駐紮飛鵝山﹐我和阿Ken據守慈雲山。Stanley用肉眼目視控制飛機而我則配帶一個8倍望遠鏡。 由慈雲山透過望遠鏡望向飛鵝山﹐可以清楚看見在該處的機師和空中的EPP飛翼。但Stanley出機後﹐我卻無法找到他的飛機﹐雖然Stanley不斷透過對講機告訴我們飛機的位置﹐但由於他眼見的景物與我們所見的有別﹐我們很難根據他的描述掌握飛機相對我們的位置。最後我們只憑運氣在空中找到飛機。接過控制後﹐我便把飛機掉頭﹐飛回出發點。我把飛機的控制交回Stanley時﹐飛機已距離他很近﹐這初步證明了在一公里外控制兩米或以上翼展的飛機是可行的. ?我們繼續嘗試﹐飛機出發後的情況跟上一回差不多﹐我們好不容易才能在空中找到飛機的位置。在回程時﹐我沒有留意到飛機的航向出現偏差﹐飛機不是飛向出發點而是在正確航線旁的一山丘。令我措手不及的是﹐該山丘突然在望遠鏡內出現﹐瞬間改變飛機的背景﹐令飛機消失其中﹗我們立刻叫Stanley接手但由於該山丘阻檔了Stanley的視線﹐他當時根本看不見飛機。就是這讓﹐飛機便掉了下來。。。 幸好阿Ken隱約看見飛機的大概落點﹐但由於距離實在太遠﹐我們對找回飛機已不抱太大期望﹐所以只是沿扎山道用肉眼搜索兩旁山坡。不料過了不久﹐我們竟然在離扎山道南風位大約200米的一山坡上看見飛機的尾翼﹗該處距離我們在慈雲山的據點有一公里之遠﹗唉﹐本打算創造模型滑翔機飛行最遠的香港記錄﹐但結果卻創了模型飛機墮機的最遠記錄﹐真丟臉。。。以下網頁顯示事發位置 http://www.geocities.com/yclui_hk/cross_country_test_longer_dist.html 幸好飛機的損毀程度不太大﹐修補後應可繼續擔任此艱難任務。 這次實驗雖然以失敗告終﹐但卻令我們領略了長距離操控飛機所需要解決的問題﹕ 1.當飛機在遠處﹐機頭或機尾向正機師時﹐機身變成一個點﹐機翼變成一條線﹐不論飛機的翼展有多大﹐飛機仍然很難被看見。 2.不論用望遠鏡與否﹐在空中搜索飛機存有相當難度。 3.透過望遠鏡操控飛機的弊端是視野狹窄﹐很難判斷飛機是否偏離航道﹐我今天在鴨寮街買了一較低倍數(6)望遠鏡﹐希望有助減輕問題﹐但想信問題仍會存在。 就如何解決上述問題大家可否提一些意見﹖

我覺得由馬鞍山到飛鵝山會更加困難,馬鞍山高度是320米、而飛鵝山是540米,要飛機飛高200多米和穿越峽谷就很吃力。由飛鵝山到馬鞍山就相對容易。我們可選擇有34級吹東至東南風的日子飛行。至於可否用望遠鏡目視飛2公里的路程,真是要試試才知。

可以考慮由馬鞍山飛往飛鵝山﹐原因是當吹東風時﹐此航向幾乎是全程順風﹐飛機逗留在欠缺升力的空域(D點與E點之間的茅坪峽谷﹐東洋山與芙蓉別之間的部份低地等)的時間較短﹐有利保持飛行高度。 要解決目視範圍不足的問題﹐相信部份機師在架駛時需配帶望遠鏡。上星期六放完機後我到鴨寮街買了一低倍數的輕身望遠鏡﹐現正設法把它安裝在安全帽或單車頭盔上﹐令機師可直接透過望遠鏡控制飛機。如可及時完成的話﹐今個周末可以在飛鵝山試試其效果。

Hi, 做髐痐皉a理功課。劃鰲X幅地圖,圖上有由飛鵝山到馬鞍山可行的飛行路線。請看 http://www.rcsail.com/map_track1.pdf http://www.rcsail.com/map_track2.pdf 此路線由A(飛鵝山)G(馬鞍山)共有5個交接點。最困難的應該是由B(東洋山)C(芙容別),直線距離有2.1分里!此外比較困難是由D點到E點是要經過一過峽谷、距離也有1公里多。我曾經在E點斜坡飛過機,升力也不錯。只要能在D點盡量增取高度過E點後應該沒有問題。最令我頭痛的是B點到C點,雖然兩點沒有什麼阻擋,但距離太遠目視飛行有很大困難。所以我另外劃了一幅圖,上有另外一條可行的路線: http://www.rcsail.com/map_track1a.pdf 這塈睄W加了兩個交接點,B1B2,又把C點輕移到C'點上。B1點高度較低,而且附近升力可能很差,但我希望飛機飛到B1點時高度盡量保持在500米以上,由B1點到B2點由於斜坡面向南,吹東風時可能不能提供升力,但如果飛機能在500米以上飛行,當到達B2點前的水牛山時,應該可以取得山坡風升力。各位機師對這兩條路線有可意見呢?

Hi, the Windstar is traditional balsa (wood) construction. This type of plane can easily be broken when crash. And crashing is one of the lesson a beginner must take... So, I think it may not be suitable for you. An EPP (發泡膠) plane is much more suitable, but it takes you some time and patience to build, but once completed, it can last forever (unless you lose it). Or you can buy a 2nd hand EPP plane if you want to start the hobby immediately... I have one old Eraser EPP, hehehe....

If my motor gliders can help, the test flight can use my big motor glider. If the motor is not ON, it can fly on both thermo and slope lift. We can use it to record the lift conditions at each point. In case the lift has problem or at some place where has serious turburance or down wind, we can still safe the plane and adjust the flying path in next trial. For testing, it should not be a problem as the pilot will not turn on the motor during the flight. Besides the Walkie Talkie, we can use mobile phone to communicate. But each station should have phones from different mobile line service company.

如果用PCM接收﹐機師交接控制飛機過程應不會有太大問題。當機師熄控後﹐接收機會進入 Fail Safe 模式﹐如調較適當既話﹐飛機應會繼續原來既航向﹐直至接手既機師開控為止。我估每站需要有兩個人駐紮﹐一人負責控機﹐另一人負責通訊同幫手睇機。此安排亦為安全計﹐因為上落山時兩人可互相照應。 今個週末不如試下用呢個方法將我隻 Highlight 由飛鵝山東風位飛去基維爾營再返轉頭好唔好﹖天氣預測吹微風﹐要靠熱氣流。我可以帶兩套發射﹐有無人帶對講機同望遠鏡﹖

Hi, to switch over from one transmitter to another is generally not so risky provided that the switch over time is short, say less than 1 second. In the past we have done some crazy things like switch off the transmitter for a while during flight, typically 2 to 3 seconds lost of signal is ok for both PPM and PCM receiver. Remember that our glider should be flying quite high on top of the mountain and there are plenty of time for the pilot in the next leg to regain control of the glider. We can use walky-talky radio to communicate and synchronize the switch off and switch on actions, but of course we may need a helper in each leg for doing the communication job. Also a helper would be useful if he can use a binocular to watch the incoming glider and assist the pilot to steer the glider while it is still far away to be clearly seen by naked eyes. With a helper using a binocular, I think we can lengthen the distance between two ploits to 1.5km. Perhaps, this weekend we can do an experiment to handover control of a glider from FNS peak to Jat's Incline. Should be fun!

A short calculation: If the course is 8Km and it consists of 10 legs, then the average distance between each pilot will be 0.8km. Note that the distance between the FNS south-west facing slope and the Jat's incline flying site is about 0.6km. We may try flying between these two points for practice.

我地初步既構思係接力式控制。沿飛行航線每隔一段距離有機師在山頭駐紮﹐負責在該點目視範圍內控制飛機。飛機離開該範圍後機師就關掉發射﹐由下一站機師接力操控。需然總飛行距離不到10km, 同世界記錄既幾百公里 http://records.fai.org/models/current.asp?id=194 無得揮﹐但由於我地係全程在山區飛行﹐故難度不比外國在平原進行既越野飛行低。整個行動要有非常周詳既事前計劃﹐除考慮點樣完成任務外﹐重要顧及安全。飛機一定要好大隻並且有特別裝置如雙接收﹐閃燈﹐高度計﹐及傳輸飛行數據用既無線電發射器等。

Hi, Last night in the HKRCSS meeting we have discussed several interesting activities to increase the public awareness of r/c soaring. One of these is to create a record in Hong Kong for a cross country r/c gliding expedition. Two possible routes were proposed: Fei Ngo Shan to Clearwater bay and Fei Ngo Shan to Ma On Shan. In view of the difficulty level we would firstly explore the FNS-to-MOS route as the mountain range between Fei Ngo Shan and Ma On Shan are mostly flyable east-facing slopes. Please see the map http://www.rcsail.com/track.jpg The route is approximately 8km long. There may be 10 or more legs from the start point in Fei Ngo Shan to the ending point in Ma On Shan. We need to do a more geological study on the possible cross over points and the flying route before the project can really kick on. Any people interested in this cross country challenge and would like to join as a team to make this record?

Ah Pong is right. If you look inside the Shooting Star, those white stuff bonding the ballast tube / wing nuts to the fuselage and making up the lips of control surfaces are mixture of micro balloon and epoxy. For bonding servos to wings, micro balloon is not really necessary as you will not be using a lot of epoxy. I would just like to mention a useful technique that I learned from Patrick Lam earlier : wrap the servos in heat shrink tubes before gluing them to the wing. Done this way, you can remove the servos later by simply cutting the tube instead of having to risk tearing up the wing skin in the process.

Microballoons are tinny balloons made by glass fibre. They can decrease the overall weight of the epoxy mixture, whilst maintain the strength. After the mixture is dried, the epoxy would be easier to sand as well. It looks like white power, and you can buy it at Tak Cheong that costs you HK$ 75 for 250ml. Happy soaring!!

Four mm movement is adequate on this sailplane. Regarding the CG, my understanding is that the CG is just a bit behind the hole underneath the fuselage where you install the hook for 橡筋彈射. However, the CG can be varied in accordance with your habit. A forwarded CG would make the plane easier to control but lesser performance. You may wish to try 'suicidal dive' method for testing the CG. Happy soaring!

Sorry I do not have the construction manual and couldn't find any information about this. So bad I may not have time to test fly it to check the CG before the competition. Also, if I install a tow hook on the belly, where should I put it? My understanding is about half inch in front of the CG, but on the last HLG competition I installed a tow hook on my MiniCorado half inch in front of the CG, when I bungee launched the plane, it was so unstable and never went straight up.

Hi, CM. I do not intend to put any limitations on the models so that more pilots can participate. The contest will consist of two parts : the hand launch part and the bungee launch part. The formats of these two parts will be exactly the same except for the launching method. I will make four Hi-starts, with each made up of 50 feet bungee + 250 feet nylon cord + parachute. It should be powerful enough for launching models up to 550 grams. Any light wind gliders of wing span between 1.2m to 1.8m will be good for the contest. We will be flying task D in F3K rules (http://home.clara.net/barcs/hlg.htm#Prov-Rules Details are as follows: All competitors of a group ( 4 pilots per group in our case ) must launch their models simultaneously, within 3 seconds after the signal of the organiser. Maximum measured flight time is 3 minutes. The model that lands first gets 1 point, all successive models get an additional point. Two models landing within the same second, according to the official timing, get the same score. The next model gets two points more. All models still flying at the end of the 3 minutes slot time get the same number of points (previous + 2), provided they land inside the launching and landing area. This procedure of mass launch is repeated up to 3 flights in total during a 10 minutes working time. The new launch may be ordered after all models from the previous launch have landed. The scores of all three flights are added to obtain the final score for this task.

上星期六日兩天我繼續到深涌放手擲滑翔機。由于手擲起飛的難度實在太高﹐故用橡筋彈射代替。雖然已找到Hi-Start用的橡膠管﹐但價錢很貴﹐醫療器材店大約賣$12一呎。 彈射1.5米翼展的滑翔機大約需要30呎長膠管﹐即$360! 在深圳買會便宜一點﹐但仍需$250. 最後我選擇了衣物用的橡筋作材料﹐把13條橡筋紮成一條粗橡筋繩﹐力度很好﹐且不易斷﹐但缺點是橡筋的彈性會隨使用次數急劇下降﹐相信只可以用兩天。但其吸引之處是價錢平﹐我用了$190在南昌街買了一盒﹐有兩萬多碼﹐足夠做超過100條彈射繩﹗ 兩天裡我大部份時間都是飛 Mini Corado。雖然她比我的 Highlight 手擲機重37%,但滯空性能卻明顯地較優越﹐下沉率很低。最初我只是胡亂的盤圈﹐飛不到40秒便著陸﹐還以為該處沒有熱氣流﹐但細心觀察飛機的動態一段時間後﹐熱氣流的跡象便陸續浮現﹐飛機遇上了上昇氣流時的抬頭和飛進了下降氣流時的墜頭動態與一般的攀昇與失速有明顯分別。有幾次還目睹了熱氣流飛行理論經常描述的一種飛行動態﹐就是上昇氣流撞擊一邊機翼時所造成的側滾(roll)。我馬上試試理論提及的應付技巧﹐就是急速把飛機轉向機翼升起的那一邊﹐雖然副翼及方向舵幾乎推盡﹐對飛機的能量損耗極大﹐但結果飛機不降反升﹐這辦法果然有效﹗ 在最後的一次飛行中﹐飛機在飛越水塘時突然遇上下降氣流﹐如當時我保持飛機的航向不變的話﹐飛機應有足夠的高度在對岸安全著陸﹐但我卻妄以為可憑技術把飛機飛帶回身邊﹐忘記了水面是沒有熱氣流的﹗結果飛機比我預計的下沉得快﹐最後掉進水裡。機上所有servo安然無恙﹐但接收機和電池便要報銷。 這兩天的飛行雖然代價頗高﹐但可以探索一下山坡以外的滑翔飛行的世界﹐總算是一項愉快的經歷。協會將在本月31(星期日)在深涌舉辦一場手擲滑翔機比賽﹐賽項之一是Man-On-Man滯空時間賽﹐4架參賽飛機同時彈射起飛﹐最後著陸的便算贏。希望大家踴躍參加。

Hi. Just bought a 9C. I wonder what program you guys would program for a 2-wing-servo plane like Mini-NYX? For airbrake, I set it to both ailerons-up (on throttle-stick). Is this good, or should I set both to go down? As for the speed-ofs, I've set it to have about 1.5mm (fixed) aileron up. Is this good enough? What else should I program for the Mini-NYX?

作日聽Stanley講深涌有好地方放HLG﹐今日就特意入去睇下個場地。深涌係位於企嶺下海海邊﹐三杯酒對面既一塊谷地﹐有一條舊村﹐但大部份村屋已荒廢﹐只剩下兩戶人家經營士多及計劃搞燒烤場同有機農場。飛行場地係位於村中央既一塊平草地﹐面積大約50m x 150m, 草地上面完全無樹﹐石頭﹐電線杆等障礙物。草地兩旁有兩個面積大約18m x 30m 既水塘﹐水塘另一面再有D面積較細塊草地﹐然後就到村屋或樹林。整個環境非常清潔寧靜。估唔到香港仲有D咁既地方。 由於該處一帶草地有士多老闆保養且部份更為人工鋪設﹐質素仲好過維園塊草地。landing 一定唔會傷機。最初我仲擔心會唔會 land 落水﹐但用我隻 Highlight 試飛後證實跌落水既機會其實係好微﹐原因係當處無也風﹐好容易判斷隻機既落點﹐如果隻機飛越心目中既落點﹐大可夾硬”頂“隻機落黎﹐由於塊草地好似一張大地毯﹐HLG咁輕既機包唔會有事。但在我試飛過程就完全唔駛用到呢一著。有幾次仲可以飛埋身用手接﹐引黎一陣掌聲。 深涌另外一個最大既優點就係有瓦遮頭。其中一家士多外面有一排大帳篷﹐下面有抬椅俾客人用﹐有飲品及食物供應﹐開餐絕對唔成問題。仲可以借用洗手間或借插蘇差電﹐真係好似係屋企放機咁﹗士多老闆仲同我講﹐如果我地入去放機﹐佢可以同我地剪晒草地外圍既雜草﹐等我地有多D地方用咁話﹗ 交通方面就比較麻煩﹐主要有兩個選擇﹐一係由馬料水搭船﹐船程約30分鐘﹐但班次好疏﹐星期日由馬料水開只有幾班船﹕8:00 am, 12:30 pm, 3:00 pm, 由深涌開返馬料水更只有 11:30 am, 2:30 pm, 6:15 pm (大約係咁﹐記唔清楚) 。如果多人搭﹐隻船仲有可能”飛站“。我今日走個陣就遇上呢個請況﹐搞到我要行路返出黎。 另外一個去法就係駕車到榕樹澳﹐泊好架車係榕樹澳村間士多外面(30蚊泊一日)後再步行約35分鐘就可到深涌。路程須較長﹐但全條路係混凝土路﹐而且絕大部份係平路﹐又有樹遮蔭﹐好易行。 協會係8月尾準備搞一場HLG賽﹐深涌係其中一個賽場﹐大家有無其他建議﹖ Y C Lui

It's a long story! I took a day off and met Master Leung and other in Fei Ngo Shan. But there was heavy mist in FNS, so we decided to explore another slope in Devil Peak in Junk Bay which is suitable for wind from southeast. I took my Shooting Star and Beetle out and had a lot of fun with tremendous lift. After a while a real helicopter circle above us then flew off, 15 minutes later two policemen came along and we immediately landed our planes, I was flying my Beetle and put my Shooting Star in the grass field not far away. We initially thought they will send us a ticket for parking illegally, instead, they warned us that we shouldn't fly our planes under the air traffic route of helicopters. Wow, we didn't know that! Anyway, they are quite friendly and they just gave us warning and gone. So we immediately packed up our stuff and drove off. What a silly mistake, I left my Shooting Star there! I didn't discover that until 20 minutes later when I drove home. I immediately drove back there to look for my miserable plane under the heavy rain. What I have found is total disappointment, it wasn't there! I am surprised since this is a remote area and there was not even a single passerby or onlooker during our stay there. People drive pass there definitely can not spot the plane - so where the plane has gone? I guess it will remain a mystery forever!

Well over 30, just lose one today. I left my Shooting Star in the flying site - only 40 minutes later when I came back to look for it, it gone! Of the 30+ gliders I have, about 14 are flyable, 14 need repair, 4 kits on the shell. I used to keep the flyable-to-repair ratio to 1:1, but it is getting really difficult to maintain when the number of badly damaged planes is on the rise. After a period of time if I could not spare my time to look after them, my wife will put pressure on me to write them off. I guess most of you have similar experience.

Dear Danny, if I were you, I wont cut the hinge. Despite I have little knowledge on using flaps; I would rather set the crow in reverse direction (i.e. flats up and ailerons down), and hoping the crow would do the same effect for slowing the machine. Other mixing such as snap flap could be set in normal manner whilst you may still DSing with it. I think Stanley and YC would give you better advice. By the way, how is your Microfloh? Do you fix it up yet? I go to Tak Cheong today for buying a Microfloh, but all have been sold out.

Dear all, I am currently building a mini-dragon with top-hinged flaps (my first flap-plane). Problem is, the flaps only deflect about 30 degree down, and the built-in hinge is very tight (same as ailerons). Can I push it forcefully all the way down to, say 80 degree. Will the hinge crack? If the original flap hinge is no good for large deflection, should I cut the flaps out and re-hinge them with silicon? Will this be a weak point when DSing (as during DS I won't touch the flap at all). Hope masters out there could give me some advice. Many many thanks.

I have talked to Master Fat Fai, he insisted that we should only allow 48" in the foamy class. The reason is; most of us have only 48" foamies and it is unfair if a 60" Gulp out run a 48" Bee. Anyway, only a few of you have 60" foamies at the moment. With repect to 60" class, he also believe that it is better to keep it for moldies, partly because pilots with mold plane are afraid of foamies in the race, also 60" foamies may not catch up with 60" moldies, thus creating dangerous cross tracking and a higher chance of collison.

Yes. But how do you guarantee your plane did not down after the collision? I think an intentional collision is not a wise act and is really a bad sportsmanship that our fellow pilots won't do! One thing is always true, that to win a game, you must complete it! If you check the rules 4.2.5 and 4.2.6, a downed plane including after a collision will receive a DNF (one penalty point). That's more worst than finishing last! I think one of the reasons here is to encourage saftey flying and to avoid collision.

60Foamy組應該沒有問題,但如果60寸公開組有foamymold機一起賽的話,可能比較危險,mold機容易損壞。我想如果只有mold機可以出賽,我們可把同賽的mold機總數減至3隻,以減少損傷。至於foamy機組,最多可以5隻機同時出賽。大家有什麼意見?

建議中既分組法可能會令 60 EPP 機如 Gulp,Moth60 等處於不利位置﹐因為48吋組又唔受佢地玩﹐參加 Open class 又多數唔夠D mold機砌。可考慮將48吋組擴大為EPP組﹐令60 EPP機都可以參加。

Hi, As I have more bandwidth and memory from the new web host, I can now install more useful features into the system. First, I will build a more comprehensive forum/chat room into the system and hope to get it running the next few days. With regard to the MoM race, I have talked to Master Fai, he suggested that we should have two classes of races in order to attract more participants. A 48" foamy class and a 60" open class. The planes used in the 48" foamy class is as C.M. memtioned. Any 60" planes including moldies can join the 60" class. Because it is an open class, we are better not to limit the plane to have a foam nose. But of course we must be cautious on the safety of people nearby. Cheers Stanley

Hi all, It is time to prepare for the MoM on Sep28! Checking the ASRO MoM rules, I think 2 of the 4 classes can be classified as "foamie": the 48" Foamie and the Sportsman 60". Does HKRCSS have any preference on which class should be adopted for our coming MoM foamie class? My problem is that the requirements on the 48" are quite strict: it is 48" and so some great fliers such as the Gulp and the Rico-SHE cannot join. And for the Sportmen 60" it only requires the nose and the leading edge to be foam, seems like I can change the nose and wings of my MiniNyx into foam and go for the race! So if the club can provide more information on the plane (especially foamies) requirements it will be very helpful. I just don't want to bring an outlaw on that day! thanks, CM Cheng

Today I try to fly my friend Gulp SR. It is fast and fantastic!

You will imagine a EPP plane will fly like this before.

The wing design of the plane not like the normal flying wings. It come with a thin and long wing like the fiber plane. The plane have very good energy retention. You can fly it with more than 3 loops simultanously. And the Loop can be very large. Compare to my JW, I think the speed is more or less the same. Maybe Gulp SR will be a bit faster. However, I find it will be easier to control in low speed also. It do not like JW, if JW slow down, you hardly can control. You always need to keep up the speed of JW.

I find something interesting to test the CG of the flying wing by doing a straigh approach. If you do the approach, the plane will tends to be drive up. Your plane nose maybe too heavy. If the plane will tends to drive down. You plane nose maybe too light. It is just something I discover today and it give me some insight for finding the CG.

Miss Carly Kong of Radar Co., Mr. Jimmy So of Waigo Model, Mr. Peter Law and me of HKRCSS attended the meeting.

John from HKRCHA originally promised to come. We were waiting for him in the restaurant for about half an hour, not until I called him and he told me he can not come. He didn't even bother to give me a call. I don't really know why, is this HKRCHA's decision not to send a representative or just because John was too busy. They have been very quiet in responding to my invitation after the first meeting, even I invited them to submit the information on their flying sites so as to pass it to OFTA for the 6 rc channels in 72MHz band, they didn't do it. I also passed the application form for the newly released channels to them and hope that they can then pass it to their members for applying the license, but when we checked with Mr. Kwok of OFTA to see how many applications OFTA has received so far, we realized that they (HKRCHA) did nothing on this! Anyway, I duly respect their professional integrity and hope that they will be more active in pursuing their goal on advancing the sport of r/c modelling.

Cheers and happy modelling!

Topic: Report on the Meeting with OFTA
Date: 23 Jun 2003
Time: 13:58:29

Message

Four of us met the OFTA official in their office this afternoon. We present our view on the sport of r/c modelling, in particular, our concern for the lack of legal r/c frequency bands. Please see the material I have prepared for

http://www.rcsail.com/ofta_meeting.pdf

We then had a lengthy discussion with Mr. Kwok of OFTA. They admitted that frequency channels allocated to r/c modelling are insufficient.

Let me summarise what we have recommended and OFTA's response:

1. We recommend OFTA to release the whole 29MHz band, in particular, for surface models. OFTA's response: they are looking the matter seriously and will start the process of legalising the 29 MHz band now and hope to set the legislation done in 1 to 2 years time.

2. We recommend OFTA to release more channels in the 72MHz band in addition to the 6 channels they have already promised. OFTA's response: they said that part of the 72MHz band is currently used by the police in operating their Robotcop. Mr. Kwok promised to write to police asking them the possibility of releasing this portion of 72MHz band. He also pointed out that the two existing r/c channels, 72.080 and 72.960 MHz, can be shifted 10 kHz to, say, 72.070MHz and 72.950MHz to create two additional channels in 72MHz band for r/c uses. So if thing went well, we might end up to have a total of 10 to 12 channels in 72MHz band.

3. We recommend OFTA to investigate the possibility of releasing some r/c channels in the 35/36MHz band and 40/41MHz band. OFTA's response: they said that part of the 35MHz band is current used by HK marine and part of the 40MHz band is used by PLA. Mr. Kwok promised to investigate which part of 35MHz and 40MHz bands will be available. He said that OFTA is willing to release these bands for r/c modelling if they are available.

4. We recommend OFTA to reduce the number of type approval tests for r/c equipment for each model from each manufacturer. OFTA's response: they fully understood the difficulty of the type-approval requirement and they are actually considering removing this requirement.

5. We recommend OFTA to waive the requirement for a license in order to operate r/c equipment. OFTA's response: they fully understood the disadvantage of licensing requirement and the poor side effect. However, they said the current legislation does require a license for using any band that are not on exemption list. Because 72MHz is currently not on the list that is why they insist us to apply for a license. He said that to set the legislation for band exemption will take ages. It is likely that the 29MHz can be exempted without licensing, however, other bands such as 72MHz, 35MHz and 40MHz are more complicated as there are other application users in those bands. He promised to investigate this issue further.

I will continue to follow up what OFTA has promised and keep you informed.

Topic: Ref: Y. C. Lui - Roll Performance
Date: 14 Jun 2003
Time: 23:05:42

Message

Hi, It is often difficult to perform a straight axial roll on a V-tail streamline glider because the weight and the area (therefore the drag) of the tail are located to one side of the axis if you view from the rear. Its inertia during a roll tends to pull the tail to one side making an axial travel impossible. There are two ways to overcome this (1) is to use a large fuselage with a bulky front so that most of the weight of the plane is concentrated along the axis proportionally. Heavily weigh up the plane; (2) Continue to perform the barrel roll and make the roll diameter about 3 to 4 span size. You can practise this barrel roll from looking at the rear end at a slope, but once you have mastered this try to do it horizontally from left to right or right to left. Do it at eye level. If you are happy then do two rolls at one time with one clockwise following another anti-clockwise in one go.

Similarly, a T-tail true axial roll is not easy to perform.

The cost of shipping the model is as high as HK$1000 which is rather unacceptable as shipping my Pike from UK has costed me only HK$500. Will shipping by surface freight be a viable option ? Will appreciate some advices .

上星期日看過了一齣由National Geographic Channel 製作﹐名為“ Wind Born a journey into flight ” 的寄錄片。該片講述一位英國滑翔機師教導女兒駕駛滑翔機的經過及兩父女連同叔父於紐西蘭的一次越野(cross country)滑翔飛行經歷。

片中畫面極具美感﹐攝影師透過精心策劃的拍攝角度﹐再配合紐西蘭山區的美麗風光﹐充份展現出滑翔機優雅脫俗的本質和形態。越野飛行那一段相信會令不少飛友著迷﹐感覺尤如置身其中。乘載兩父女的滑翔機由於翼荷較重﹐父親沿途需不斷修改飛行路線﹐盡量利用山岥風和熱氣流爭取高度。旅途中滑翔機曾數度因缺乏昇力而降致危險高度﹐最驚險的一次是當滑翔機飛越一高山湖泊時﹐飛機僅在觸到湖面前一刻從湖邊的瀑布頂離開。曾在昇力不足的情況下嘗試把模型飛機帶回身邊的飛友﹐想信對那種感覺不會陌生吧﹖

該片還介紹了一種鮮為模型滑翔機愛好者認識的滑翔原理 wave soaring。這種滑翔原理倚靠一種名為lee wave的氣流產生昇力。與一般人熟悉的山岥滑翔或熱氣流滑翔最大的分別是﹐lee wave 所產生的昇力可把滑翔機送到五萬英尺高空﹐比一般噴射引擎民航機的巡航高度還要高萬多尺﹗更神奇的是﹐lee wave可在遠離山脈﹐沒有山岥上昇風或熱氣流的內陸地區出現﹐它所產生的昇力順滑如絲﹐連綿不絕﹐滑翔機師稱之為” 通往上帝處的升降機(the elevator to God) “。

看過該片後﹐我對滑翔飛行運動更為神往。透過對自然力量的了解和精妙運用﹐滑翔機師能跨過崇山峻嶺﹐橫越荒蕪。飛向天際。近年Dynamic Soaring 的發明更打破模型滑翔機的速度屏障﹐一位美國模型滑翔機師便於大約兩星期前創下了每小時332公里的驚人速度記錄。能做到這些而無需倚靠任何引擎動力﹐就是滑翔飛行運動的攝人魅力所在。

該寄錄片的VCD可向師傅梁借取。有興趣的飛友請與師傅聯絡。

上次開會時,我題及是否應於飛行中看不見飛机時•開啟 butterfly ,以減慢飛机的速度,使它撞下時的力度減至最底。當時你說spin才是最慢的。但我回想一下,發覺很困難。如果自己看不見飛機,是否真的可以使它進入spin呢?可否加以說明!

如果OK的話,相同的方法也可設定於 PCM failsave mode。那麼當 Jam 机情況發生時,也可減少對飛机或人的傷害!

Yes, the frequencies for the 6 newly released channels in 72MHz are exactly as Willy mentioned. Let me repeat here:

72.010, 72.130, 72.170, 72.190, 72.210 and 72.270 MHz.

OFTA has already confirmed that. I have given this information to Radar and then Futaba. I guess they will stock up some crystals to meet the demand.

If you are already using 72MHz band, please check your frequency, if it is not one of these, you might subject to interference by other radio users.

The two old frequencies, 72.080 and 72.960 MHz are not inline with the r/c channels so OFTA will no longer issue license to these channels. Existing users, I believe, will be phased out.

I am convinced that there are more r/c channels in 72MHz which may not yet be occupied so if we can prove to OFTA that our demand for r/c frequencies is high, OFTA may consider releasing more channels on the 72MHz band.

Hi all,

I don't have the knowledge or equipments to make exact measurements. However, I know a place in FNS where even with my 9C switched on, my sailplane will still get intereference. I can show you the effect if you are interested. With this sample on hand, it might be easier to find the source of the radio intereference!

Hot discussion on this subject has been going on for quite a while in this forum and in that of the RC helicopter club http://www.hk-aviation.com/cgi-bin/topic.cgi?forum=11&topic=400&show=0 but despite the large number of posts, there have not been much constructive ideas, fact-based arguments or contribution of useful information like those given by ENG. Assumptions, flames and un-grounded criticisms will take the RC modeling community to nowhere but a dead end.

Now we are going to get more spectrum on 72MHz and OFTA has indicated the possibility of releasing part of the 29MHz band for RC modeling use. There have been claims that these two bands are dirty but so far I have not seen any objective evidences but just remarks like “係人都知架啦“。 Is it possible to perform some measurement ? Can we take a measuring receiver to popular flying sites in weekdays and do some data logging ?

Can 36MHz interfere 72MHz? The second harmonic of 36MHz is 72MHz. A poorly adjusted or overpowered 36MHz transmitter can radiate second harmonic signal which interferes the 72MHz receiver. According to OFTAs frequency allocation table, 36MHz is assigned to wireless microphone with maximum power of 20mW. A Futaba transmitter is allowed to transmit up to 500mW which should be strong enough to preempt the signal of wireless microphone due to the capture effect of frequency modulation.

Can 72MHz interfere 36MHz? It cannot, because the harmonic of 72MHz is out of the band of 36MHz. However, if a 72MHz transmitter generates its carrier signal by doubling the output of a 36MHz oscillator, then that 72MHz transmitter can interfere a 36MHz receiver when it is in the vicinity of the 36MHz receiver.

Also, please note that according to OFTAs frequency plan: http://www.ofta.gov.hk/freq-spec/freq-allocations.pdf

26.96MHz 27.28MHz are for model control equipment at maximum power of 0.5W, and are exempted from licence.

The 40.66MHz 45.5MHz band is assigned to lower power (20mW) equipment, e.g. wireless microphone, cordless helmet.

The 28MHz 29.7MHz band is assigned for amateur and amateur satellite. I think that is not being officially occupied by anybody.

哎,最近實在太忙,但無論如何也要回應KK的留言。請"千祈唔好扯火" 29MHz也有FMPCM的系統,所以我唸放直升機都冇問題。澳洲、紐西蘭和星加波都是用29MHz。當然29MHz比較接近27MHZ CB頻道可能受到較多干擾。而且Futaba也明確表示不會放太多資源係29MHz產品發展,希望香港也用35,4072MHz。但事實35/36MHz巳被香港紀律部隊用了,部份40MHz又被解放軍用了,部份72MHz又被貸車、的士用去,試問我們還有何選擇呢?做成這個現況,我想我們也有多少責任。如果我們能早幾年前搞申請,40MHz就唔會被左解放軍。其實OFTA並非不完全接受我們的要求,過去十幾年根本就冇人去搞過,就算有只是點到即止,沒有死纏攔打。而家有人搞,OFTA亦願意與我們遘通,為什麼這位仁兄還要反對,說什麼"老鬼會"靠人仕也搞唔掂。老實講,"老鬼會"提上去政府申請大樹下場地慨Biding Document我都睇過,雖然他們猛踩我他係清水灣馬路邊放機唔安全,以抬高他們的身架,但他們的Document做得很有心機、長編大論,試問你有沒有做過野?唔做野就要政府批甜頭你,有冇咁易!

事實上今次我地搞起亦困難重重,好彩有各方人馬支持。我們約左OFTA肯坐埋傾傾巳難能可貴。我盡量在開會前寫個Proposal,內容抱括開放29MHz的利弊,如可能的話把Surface,Air models頻道分開,要求開放部份還未用的40MHz band給飛機等等。如各大機友有何見解和要求,請盡量提出,整理分釋後會向OFTA反影。還有OFTA會在6個月後撿討開放後72MHz6條頻道的申請情況,如果發覺供不應求,他們會考慮開放更多72MHz的頻道。最理想是29MHzsurface models,40MHZ 10條頻道和72MHz 10條頻道給air models

KK兄,我亦不防同你做個Test。你用驗証合格的2W 144MHz對講機在100公尺外Jam我隻72MHz接收機,看看有沒有問題。清水灣見?

Willy 就講得對啦。除非執政者真係打橫黎﹐唔睬我地﹐妄顧我地既需要同利益﹐我地或者仲有D理由去知法犯法。但以我對OFTA既了解﹐佢地絕對唔係咁。佢地雖然做野手腳慢﹐驚D樣驚個樣﹐但係如果你俾到足夠既事實﹐證明額外既遙控模型頻率係一個頗大社群既需要﹐佢係唔會唔做野。事實亦證明﹐現在已經有D進展﹐作為模型界既一份子﹐我地好應該多多支持。

”朝中有人好辦事係事實“係對﹐但係朝中無人唔代表辦唔到事。以前向政府爭取過遙控模型頻率既人 可能就係太倚賴” 朝中人 ” 而唔嘗試其它途徑﹐結果就也野都做唔到。依家 72 MHz 將會多6條頻道﹐29MHz又有得唸﹐我覺得好唔錯架啦﹗

KK 對無線電干擾既原理可能有少少誤解﹐但呢個論壇並非講無線電技術﹐所以都係唔好浪費版面啦。我都相信只要功率夠大﹐144MHz 對講機絕對會干擾到72MHz, 但做成呢種干擾既原因與Stanley先前解釋過既唔一樣﹐同72MHz係唔係144MHz 既一半無關﹐60MHz75MHz 等接收機在同一情況下都極有可能受到干擾。

噢,上述或可構成被控「非法使用無線電器材」的求情理由,我律師行若代客出庭就此控罪求情的話,必引述此等高見。

事實上,玩 jet 的那班人士,據我理解,是異常守法的。《民航處》曾向我透露,由於該些機種,重量超過 7kg,不再屬於 Air Navigation (Hong Kong) Order 1995 (Cap. 448C) 內所謂的 small aircraft,因此全數受該條例規管,並需向《民航處》申請註冊及必須接受該處的條款,而有關機主亦有這樣做。相比之下,有幾多擁有重量超過 7kg 的滑翔機的機主有咁做呢?

有人凡事都想奉公守法,拿正牌用遙控,這是好事。

你在前面的留言說"72MHz144MHz的一半,會被jam到飛起的理據絕對唔成立。接收機一般都會有個Bandpass filter,頻率高一倍的信號未入superhetrodyne前巳被filter走。況且接收機內有一兩級中頻,72144之差頻一定過唔到中級。還有,無線電波在經過Nonlinear Channel時,頻率只有倍增,不會除半的"....你話冇事?好?,我?做個test ?,你出機用72Mhz頻,我用一個144Mhz發射機jam 你,睇?你隻機會點??講冇用?test?or?D無線電高高手啦

Hi Paul,

I have been making simulator cable for some pilots free of charge (material cost is only about $15). The cable is for connecting Futaba transmitter to PC printer port for the FMS simulator. If you are interested I can make one for you. As mentioned by Y.C. you can download the FMS simulator and also many aricraft models including glider and helicopter. Do a google search on "FMS simultator models", you will find out more.

Happy pc soaring!

You can get free simulation software from FMS http://n.ethz.ch/student/mmoeller/fms/index_e.html. There are instructions telling you how to make the interfacing cable.

I have also been told that a simulation software called "G2" is available from 卓藝.

I was told that there are computer software for r/c glider simulation. As a beginner, it may be helpful.

I also hear from Wai Go that there is a USB cable to connet the USB port from computer to the trainer cord of the transmitter so that you can use the transmitter instead of joystick. But they do not have stock at this moment. Search in web site shows an attractive product but cost over $100 US.....

The Hong Kong frequency spectrum allocation plan can be found at http://www.ofta.gov.hk/freq-spec/freq-allocations.pdf

72.08Mhz and 72.96Mhz are assigned for model control.
