nano cpx

I have a nano cpx and durring hover the heli starts to have a slow wobble and continues to get worse with no input. i can stop it by conroling the sticks but when i go back to stationary hover it starts to oscilate again. It didnt do this when it was brand new. can someone tell me what causes this?

I just replaced the feathering shaft and its still doing it. The main shaft is carbon fiber or plastic so i cant see that being bent.

Was it like that before? Have you checked the blade tracking?

Mine does that if the main shaft gear is too tight against the frame. Try backing it off a little, but not too much or it won't lift off.

Have you changed your throttle curve recently? I put mine a little low on my mcpx and I was getting tail wag and crazy vibrations. Going into idle up the problems would go away.

Otherwise so far I hate my nano because I got bad tail wag out of the box. Horizon's working with me on it though. I think it's my main motor at this point.

When you replaced and tightened the spindle did you make sure to leave the grips free to move? Are the blades loose in the grips? Is your 3in1 screwed in all the way to the frame? Good battery?

There's a nano thread, http://www.rcgroups.com/forums/showthread.php?t=1719536 , you might want to try searching there for an answer too.
