直升機基本知識

請問師兄們有無D網站講最基本搖控直升機概念。我連點解可以倒轉飛都唔知。
thanks

我都恐想學吓

我都好想由基本知識開始

知道基楚理論是一定要的,幫助修機,想飛得好就是不停去練習

同意，我以前就係冇基楚理論所以咩都唔曉

ching, I also wanted to know.

thanks

   我也有同感?

因為內容在其他Forum.所以不發到版

點解可以倒轉飛-------------其實原理就類似風扇同抽氣扇一樣，如果rotor 是順時針方向轉，正pitch 做風扇，風向下吹，那負pitch 時，風就向上吹，像抽氣扇一樣。反飛時機体形狀是rotor 向下，那抽氣扇吹出的風就托著部反飛中的直升機。

如解釋不詳請見諒。

師兄正確,其向前向後,左側右側都好似風扇一樣,而控制這風扇.就是servos.

所以----------------

    3 D flying 就是控制直升機可不停轉變機体位置(hence, rotor disc) 到你預知的高度、方向、位置等，及在安全情況下，做出優美而連貫的動作。如能配合音樂就更佳。

plx pm me~~~
thx ching
新手機有冇介紹??  我6月中想入CB180Z

CB180Z,我覺得係玩得過

想問下, 咁係未要有個制轉PITCH先得, 即係4channel唔夠?

回復 48# fffguy


Nowadays, there is no switch specially for change of pitch/collective among +ve & -ve. Although such design can find in some obsolete designed transmitters.

Throttle channel is mixed with  collective channel. Usually in flying 3D, throttle is keep at a high (rotation per minute) RPM, i.e. the throttle  is keeping at e.g. 100% RPM. As the channel of throttle and collective is mixed, hence, the stick for controlling the pitch with centre is 0 degree, highest stick position is 10 degree whilst lowerest stick is -10 degree. Anyway, you may need a 6-channels control for flying 3D helis.

You can imagine the rotor is keeping at high rpm. Any change of throttle (collective) stick position can bring the heli in all direction no matter it is up right or inverted.

Thank about it. Above degree figures (+10, -10) are just for reference. In some helis, you may set to + - 14 degree without binding.

Oh! Brother Chiu, thank you very much for your reply. I now know the critical reason why helis can fly upside down. The point is: "throttle is keeping at a high, the pitch degree controls the air flow direction !!"

I've really learnt a lesson!!

我都想要，因為飛極都唔好！

gary兄真身苦你,每人都有人問你取經,努力呀大師兄!

都系個一句最緊要安全
