好易整，好易飛，非常好玩
翼展 2 呎，唔算細機但係用細機既成本，o岩哂鍾意經濟既我

去片！

how do you turn?

同真飛機一樣，呢隻 F22 有：

1. 水平翼 elevators ： 控制機頭上下 (pitch)
2. 副翼 ailerons ： 控制機身左右番滾 (roll)
3. 油門 throttle ： 控制摩打速度

即係一架 3 通（channel）既搖控飛機喇。同真飛機原理一樣，轉彎係透過左右翼浮力既差異。
例如轉左既話，將機身向左 roll，左翼會比右翼低，而左翼浮力亦會較低，飛機就會向浮力低既方向飛去，做出轉彎動作。如果 e 個時候再將水平翼拉下（pitch up），更可以將迴轉半徑減少。

因為係簡化既關系，垂直副翼 rudder 功能省略左。有興趣可以加上，加上之後就變成 4 通，理論上可以做到例如水平轉彎 (flat turn) 等動作。

希望多 d 人可以一齊享受 RC 飛行既樂趣啦！

嘩好靚喎！呢隻睇落似係 32" wingspan semi-fuselage，有冇圖呀？你去邊度飛架？

How much time and money to assemble on of these, including remote. Thanks.

I like to Google things for some people that wouldn't do it themselves. ;D
so that thing is not mine, and it belongs to this guy: http://www.pbase.com/atkelley/todd

I think around 200 dollar should get you one and probably takes about a few hours to build.
Seems to be glued together as with most RC planes. Dunno if there are kits that includes the expensive bits like the engine, servos, radio, and radio...

where is the ailerons again?

or its just the same with you elevator?

your prop is reversed wor.....if possible reversed it .and it will increase the lift efficiency.

time to add wheels on it la

How come the motors that control the 水平翼 elevators are exposed? Will they introduce additional drag to the plane? Can your plane land on non grass land? I think it will screw your propeller
