生哥, 唔好太介意机重, 330g 左右是可以的. Task 的比賽, 並非單玩超輕鬥耐, 如其中一項Max 都只是計4 min, 並非鬥捱, 同時要清醒善用手上的飛行時間, 玩Task的技巧和戰畧十分有趣, 參予才是最佳的了解方法.

Who else is interested in going to Humen in Dongguan on Dec 9th for our contest?
So far the following pilots from HK should be going:
Thomas Lee
Michael Pang
Kin Cheung
Stanley Chan

Come on Johnson, Allen, and everyone else :) It will be a great experience, hehehe

9 Dec is our F3F Dec league.
It will be an important contest to determine the first tier HK F3F ranking of the year. The few top guys will fight neck to neck for a thin margin to win.
See the running league score here:
viewtopic.php?f=2&t=2291&start=23

as well as the 貝納頌 and 保礦力 challenge s of various groups. I think Stanley will probably stay in HK.

CM and I will the CD and helper that day.
Sorry cannot come to DLG.

Yes, I will stay in HK for the last important F3F race on 9 Dec unless it is cancelled one day earlier due to weather consideration - no wnd?

我隻機落水後,個4 ch接收和一隻wing servo死左,另外兩隻尾servos疾步,暫時都無咁快找到咁細的接收更換。 :cry: :cry:

How do you fit 750 & 1200 mah batteries into your dlg?
What is the size and weight ?
What brand and model is it?

Mak, 1s 550mah is OK la. You can get it from rc cars shop at 廣华街. They are mainly used in Mini Z car or tiny helicoptor so the discharge C is higher than enough. Of course you can get similar at 鴨寮街 at uncertain discharge C with a cheaper price.

Just to remind you there are 1s LiFe (3.3V) cells in the rc market but it is not good in DLG application.

Hi Mak, that battery will work, and is convenient if you are switching from nimh. You will need to add more noseweight though.

I install my batteries before servos, and they are not removable. I do all my charging and on/off via a switchjack.

Image

You can see in the photo my 750mah 1s lipos. I don't have their dimensions, if you want I will measure it when I get home. I bought them from Hobbyking for ~$2.5USD each shipped to Vancouver.

Now I bought some round cell (14500 type) 1200mah 3.7v batteries to use, they should help me eliminate most noseweight (I use carbon tails, so they are 2 grams heavier than glass tails).

Image
these are ~4RMB from Taobao

Oh ! install batteries before servos ! ?
That mean you have to know your CG before your plane was built.

If you buy UltraFire batteries from TaoBao, beware of false batteries.
A lot of them doesn't give the quoted amp.
even the real UltraFire (a Chinese brand) are always over quoted in capacity !
( I used UltraFire before. It don't last long )

It is best built that way in my opinion. If you use the switchjack, you can charge it very easily and never need to open the fuselage hatch. You need to balance the CG before you glue the servos, it should be pretty close, then glue it. Then afterwards, you can finetune the CG with very little lead.

That is only the photo, the ones I bought are Sanyo (I think, maybe fake too, hehehe!!!!), but I tested them with a discharge and charge and they are almost 1100mah, so quite close to advertised 1200.

If you can buy the Hyperions or Turnigy's, those are great. I love the Turnigy nano-tech batteries but I cannot order from Hobbyking when I am in HK :( Do you know if they sell Turnigy cells locally?

Thomas, you may try to access H.o.b.b.y.k.i.n.g or sometimes similar on ebay. Turnigy brand does not appear in local market but a walk at Kwong Wah Street may work.

By the way, what charger setting do you use for that 18450 cell, Lion , LifePo??? :?

Hi Johnson, good point. I charged my cells with 1s LiPo setting on my Accucell 6, usually at 3-4C, and sometimes 0.5C-1C if I want to fill it to almost full capacity.
Thanks for the tip on Hobbyking, I'll give that a try, their turnigy's are so good.....

Thomas

小小建議:

如何吸引更多人玩 F3K ?

飛 DLG 同飛斜坡完全不同, 我玩過兩次 DLG, 完全唔識掉上天,叫我去比賽簡直無癮!
而且咩task ABCDEFG, 九廿幾個task 都唔知up 乜?

不如搞次F3K 訓練日,教下新人玩下仲好啦!

ps: 請組長及各位盡量以中文發帖。

If there is enough interest, we can do a funfly/practice/intro session in December or January.
I can do a short launch clinic, and a brief intro on how to setup a DLG (flightmodes/presets/etc).

We can then fly for a few hours and then explain the different tasks. Then we all fly 1 task together so everyone knows what it's like to fly a task.

Sorry, I cannot write Chinese very well :( So I need to post in English.

其實,興趣係自發的,如果一開始就抱著這種心態,搞幾多訓練日都無用。

興趣班你畀錢都參加,因為你對該事物有興趣在先,君不見很多小孩被參加興趣班如受罪,因為他們根本無興趣。

另請勿介意,Thomas他不太懂中文的。

有心人可於国內熱熾的網站找到很多資料, 高手云集, 保証加速上手, Task方面就必須親身參予啦, 非旁觀者的感受.

http://www.tsmx.cn/bbs/forumdisplay.php?fid=158

君不見Michael只是由自己主動打電話給Thomas就能得到無限支援, 火速到位?

飛Task ? Youtube 唔使我教啦,
當然還有RCgroups.com

千里之行, 始於足下.

Have you recently chatted with my son, who complained against his Tiger Mother ?

心底話...

香港小場地是一問題... 要找新場地! 靶場可試下向有關方面申請! CM 好肉在努力中...

另外推廣有乃我們協會繼續努力! 沒新血就沒有活力, 否則會繼續如以往咁多年比來比去都係果幾條友!!

你地都唔開班教人, 想玩都無心機啦! DLG 要人教... 真的!

我識好多機友都想學... 上次深涌我都都帶了兩位新人加入. 我跟本唔識! 想教也不能! 步伐. 轉身. 手指楂機. 楂控技巧應該如何呢? 機的 Setting 又如何呢? 都是新人大問題!

如有活動, 我會盡力於加載於 Rcpro 網頁公告! 有 DLG 班上, 好野! :lol:
Thomas, 有新人活動我們會幫手翻譯... 明年 "熱氣流小組" 靠你加把勁推動了! :wink:
