RC Slope Soaring in Hong Kong

前晚同佐治﹐阿堅﹐ Eric 食飯講起好唔好搞番個電機 man-on-man pylon 賽。pylon racer 雖然機仔細細﹐但一D都唔平﹐為左唔好令比賽變成燒銀紙賽﹐耶魯兄弟有意整批 speed 400 級既纖維 pylon racer 出黎﹐用較相宜既價錢供應俾大家﹐賽例會限制電池數量﹐摩打又只可以用 400級 有炭擦。mini bee + 自制無炭擦既速度幾好﹐相信會係一隻幾好既 racer.

唔知大家對呢種比賽有無興趣呢 ﹖如果多人有興趣就可以下次開幹事會時討論下。

是否分兩組，一是耶魯 F5D + stock speed 400，另一是 Mini bee / Bee + home made CDROM motor?

Both are interested

依家只係提出黎傾下﹐點樣玩法就要睇下各人既意見。譬如可以整個 unlimited 組﹐等D勁無炭擦+勁鋰電+勁機有機會飛下。其實眼見好多玩電機既人都用無炭擦摩打﹐如果人數夠多﹐都未必要限人用 speed 400。因為可能會幾慢﹐唔夠刺激﹐但唔限又會變左玩鬥荷包﹐幾難唸。

支pylon要炒唔斷先得喎

提倡Ｓ400会好玩Ｄ. 玩開power机的已經自有自天地,stock對佢地都有挑戰性呀. 一旦開咗unlimited以後就無人玩stock 喇

How about to use same brand of motor? Windrider speed 400 motor?
Each HK$30 special offer for this man-on-man pylon 賽!

I prefer the race to be divided into an unlimited class and a stock class.
Stock class must use 400 class brush motor with limitation on no. of cells or maximum input voltage, say max. not > 8.4 or 9.6V.
This can reduce the investment while one can still enjoy a competitive pylon race.
Unlimited class is no restriction on the equipment being used, provided the plane is electric powered with brush or brush-less motor. In this class, everybody can put their rocket science in to build an ultra-fast racer : A good way to burn your $$$ and to crash your plane!!!
Of course, safety is the most important. Some restriction on weight and dimensions must be established.

Ah! I don't prefer man-on-man pylon. It's extremely exciting, especially on unlimited class. Top guns with good pilot always wins. Even experts can create a lot of crashed rubbish.
Besides, one will have to prepare more than one plane for the race. Killing rate in a man-on-man pylon should be high as the stress not only come from speed but also the mad dogs which are chasing you from 3 dimension + the 2 pylon posts.
Speed race in a close circuit,1 competitor by 1 like the F3F as more preferable as the 1st time to organize E-pylon race.

One more aspect to consider is the racing format. F3F's format is easier to manage & requires 2 helpers at pylon A & B and a time keeper. No signal will be issued when the plane has past the pylon. The helper will only signal for the cut that does not past the pylon.
Compared to a 2 pilot man-on-man, helper A & B are required and the time keeper now have to watch for the plane laps on the slower one in the allocated flying period, Then the race can be ended.
For multi-racers man-on-man, it's really a mess that will require helper A & B, an over-all timer-keeper and 1 time-keeper for each racer. Can we afford to have so many voluntareers?Remember, most of them are the pilots. I believe, one can get enough task force at the 1st round. As there will be a killing field, either it will end up with pilots being engaged to fixed their injured planes or there will be a lot of helpers after rounds.
Grouping the pilots for man-on-man is difficult. I dare not to be put in the group with YellowBrothers or George and some more excellent pilots. Surely, I'll be a helper after the 1st round if the race is not held in combination of 'double rounds'.

As in F3D/F5D, do we need two "cages" for the safety of the line judges? For MoM putting 4 or 5 men in a cage is pretty interesting

The Pylon Piker standard seems to be quite suitable and affordable for most people:

Something for you, KINKINKIN, plaese take a look on the following webpage:-

Looks really nice.

How is the progress of this event? Yello Brothers, how are you projects?

HKRCSS has decided to organize an electric pylon race on 5th June 2005.

We are now working on the racing rules. Suggestions and comments are welcome!

Is it possible for HKRCSS provide certain general guidelines now ? I need to understand requirements like wing span size, motor and battery limitations etc. We need time to buy, build and test fly electric planes

In the HKRCSS committee meeting last Sunday, we have discussed the preliminary rules.
Basically, the pylon track will be between two poles of 100m apart and it is a timing event much like F3F. The fastest will win. In order to get some experience in organizing such event, this time we only allow flying wing made of EPP. The wing span is limited to 48". The motor can be brushed or brushless but with a rating of 400 class only. The battery is either 7-cell NiCd/NiMH (8.4v) or 2-cell LiPo (7.4v).

Proposal on the track as the F3F is good & easy to manage. However, I don't agree with the race will only be limited to EPP flying wing for the 1st time. In fact, the race can be organized into 2 classes: =< 48" EPP and =< 1m (or around 1m) plane. It'll allow the participants to have their choices to start with. Firstly, it may start with 400 class or equiv. motor with the battery spec as said. This arrangement allows the flexiblity to upgrade the power unit for the later events instead of dropping the EPP and switch to other type of pylon racers for performance advancement.

Ah ?! Is flying wing a must ? How about EPP or foam material made <= 48" planes, with prop in the front ?! The popular 小白 ok to participate or not ?

Stanley,
I remember we only limit the cell nos. and the size of the plane, no limitation on the material during last meeting. Please correct me, if I 'm wrong.

Hi Alex,

As far as I understand, last time some members, in particular, Ming Fai, suggested that the race should be for the flying wing only.

The question is whether we can allow only one wing at a time or maximum 3 wings racing together simultaneously.

If other fellow pilots interested to have another class for moldies, I have no objection but it must be one plane at a time.

From comments made by fellow pilots, should we hold two classes of competitions instead?

Foamy class: wing span < 48", multiple planes (3~4) on the race simultaneously - really good fun to look at! Race according to a race matrix without timing just like Man On Man race.

Open class: basically for moldies, wing span < 48", one plane at a time, F3F style of timing.

Can these two classes be held in one day?
Suggestion and comments please!

Since it's run like a F3F race, where there are no danger for the moulded planes.
There's no need to put EPP planes in another class.
Keep it simple !
