BTW, that photo, the yellow color canopy belongs to "koon" and the transparent is my one.

It was taken on the same day as in the video.

Oh...Thanks "tudole" for helping me translate it.

You 're welcome!

Yeh, I figured out you're in Singapore. I did see your post in RCgroup... no wondering it looks familiar to me.

For all viewer's information... if the rotor rotates CCW, it's called "American rotation", in the other hand, CW is called "Russian rotation".

Let's speak English

The tilted tail version looks COOL!!!!!!!!!

Breifly translate Mr. Pico's comment: 這是DIY的 還是有廠家在做這個套件 是為了要裝相真機殼嗎 Is this your DIY project or a kit supplied by some manufacturer? Is this an application for scale models? 以前我一直以為停懸 會側傾一邊 是因為 反作用力　跟 反反作用力 的施力點不同平面造成 I thought helicopter hovers with slight roll attitude is caused by the moment created by force and reaction force applied in different planes. 如果這樣改翹尾 停懸還會側傾嗎 Will the tilted tail improve the helicopter roll attitude in hovering? 改這個 是為了像真殼安裝 還是只是要這樣玩呢 以前國內有改過從底下裝尾管的嘗試 效果也不錯 Are you doing this modifacation for scale project or just for experiment? Someone in Taiwan had the similair approach, it seems to have a good effect. 您的這個改裝看起來還不錯 先前有看過相片 VERY GOOD JOB!　 It's a cool modification, I saw this mod in pic before... 補圖 BY PICO

這個設計我喜歡.....
好水喔...

Hi Hornet

Could you post more detail as fig section?
Or structure.
Thanks

The fig

I try to post some close picture if possible. My Video Camera closeup is very poor quality.

That part is actually a mechanical throw reduction. It reduces the pitch throw and also amplified the servo torque.

The reason I did that is because:
1 - TRex swash plate size I considered very big. Therefore, small movement in swash plate will result in bigger pitch throw.
2 - Mechanical TRex has alot of elevator freeplay. That freeplay will effect the cyclics and the pitch/collective if I connect directly from swash to blade grips.

How is control feeling before and after retrofit?
This is actually i want to know.

U mean the mechanical reducer? It was there all along. If u read the RCGroups (or Daddyhobby) forum, I did mention the various version till I finalize on that kind of reducer.

Anyway, the reason I use servo horn instead is because I have it lying around. It also allow me to try different reduction value.

This is what I can say for the moment:
If you are running true CCPM, then maybe u can run without the reducer. If yours is conventional TRex mechanical mixing, then it is better to have the reducer. That is because our mechanical mixing TRex has too much freeplay. Using reducer, it also reduces the unwanted interaction to the cyclics and thus better/stable heli.
