View Full Version : Tail swing
02-17-2007, 10:07 PM
Is it normal for the tail to swing way right when giving the CPP full throtle?
I have the G90 GYRO AND A NEW TAIL MOTOR (MY 6TH ONE) installed and when I go full throttle the tail always swings right. A total pain in the butt.

Are you slowly going up to full throttle or doing it quickly.
I have stock everything, but when I jump any direction with the throttle quickly the tail can never keep up. Might just be my stock crap sucks or something though.
I said this in another post too. Try the screw on the 3 in 1. I thought there was something wrong with my CPP until I found the wonderous screw.
(I could be totally wrong and giving you bad advice, but that is what I would try)

Very quickly. What screw?

There are two tiny white screws on the left side of the 3 in 1 if you are looking from the tail. You will have to check the manual on which screw is the tail one because I can't remember off the top of my head.
Turning it clockwise should give the tail rotor more power and counter is less power.
If you can't find your manual or something just post and I can go dig mine out.

I found the problem. I used the dual motor alum. upgrade but took it off. Anyway, the problem was the blade pitch ( I think thats what you call it ) I had my blades set so I would get lift at less throttle. Well it would seem that the tail motor is partialy controled by the head speed or how fast the main motor is running. So I set the blades back at zero. What a difference. Much more stable flight and the tail is pretty much locked in as much as a CPP with g90 can be anyway. Good news is I have a few extra tail motors LOL. I'm not exactly sure about the main motor tail motor relationship but it seems to have worked like a charm. And to think I was actualy going to shelve the CPP. Looks like I'll be able to fly while building my Trex war chest :D
