先確定飛得起先搞塗裝啦

重有 4 粒 engine pod 都未整

I can't comment on the lipo until the first flight, I'll post the result later

FYI flaps are mixed in the aileron, they are called flapperons. With a flip of a switch on the Tx both flapperons go down about 50% and they work as flaps and ailerons at the same time.

YEAH!

CG 太後，不過首航 ok 啦！

放心，我已經響 Aileron 同 elevator 較左 -50% expo，加上 CG 移前半寸，應該會好好多架喇！

CG: 19.2"
槳： GWS 1047HD

Torque roll 問題少左好多，平飛可以講係順左好多，應該距離完美 CG 不遠已！不過響側面風既時候 body roll 既問題有待解決，可能要動用 gyro …

咁又唔駛開班咁誇，一齊研究下囉。請收 pm

其實真係唔係一般人想像中咁難，當然有 d 基本技術同理論要掌握既。初心者可以由簡單既平板機型學做，一步一步提升技術。小弟都係 DIY 左一年多少少 既初哥，大家交流一下囉。

有興趣既話，請 pm 聯絡方法，可以搞個 LYK 模型飛機聚會。等各方高手指教分享

For smaller (500g all-up-weight "AUW" or less) electric-powered models usually you don't need one. Just make sure the park you're flying at does not explicitly ban RC model flying. I usually pick a vacant soccer field to fly and I don't fly my planes anywhere close to people and their pets.

You may join flying clubs if you are to fly very large models. The annual fee includes insurance coverage for flying at the club. There is one in Burnaby and the annual fee is $100 something.

My flying field :

Even my fly buddies who lives in bby/vancouver come to here to fly, this is probably the best in town. Come join us

Concerning the plane u wanna buy, it's probably better to get proper "hobby-grade" gears than a starter kit like the sky hawk glider. The reason is price/performace ratio and affordability.

You may think a starter kit is cheaper, it is in fact very expensive even for short run. Take sky hawk glider as an example:

http://www.r2hobbies.com/proddetail.php?prod=rcpl51028

- The motor is a cheap brushed motor - lack of power when you need it and does not last.
- The ESC (speed controller) is undoubtedly for brushed motor - need to be replaced when you outgrow your brushed one (very soon)
- The battery is either NiCD or NiMH, which is heavy and wimpy comparing to lipo (lithium polymer)
- The FM Transmitter ("remote" in outsider's terminology) does not allow you to hook it up with the computer for simulation. Very few newbie RC pilot can start flying properly without training in the computer sim first

So you are paying $60 US + shipping for something that will probably last 10 seconds before ending up in a pile of debris.

With similar amount of money, you could get some basic, yet proper hobby grade gears such as:

- brushless motor and a brushless ESC combo
- 2.4Ghz Transmitter/Receiver set
- hobby-grade heavy duty servos
- lipo and charger

Concerning the airframe, it can be ridiculously cheap to DIY one (I can show you how, even build for you if necessary) using readily available material from local stores.

Foam: Homedepot, 1 sheet $7 for 10+ planes
Glue: Homedepot Weldbond, $5 for a large bottle
Pushrods: Piano wire, $0.9 a pop you prolly need 2
Wood motor mount: Daiso craft wood: $2 u can make a bunch

For starter you may want to fly something easy and slow, like the following:



Let me know if you wanna get started. Everyone is welcome

Mash: 第二個 flight 同第一個 flight 既分別係重心／CG (centre of gravity)。第一個 flight CG 太後，冇炒真係好彩。

唔明咩 feed back controller 囉，force feedback？嘿嘿
