Bad wobble in st1 & st2?

[baevans111]

I have the brushless motor on my cps and it wasn't bad when I first added this motor so I don't know if that is causing my wobble but when I ok so it looks like it's having a seizure. Another problem I have is I have very little servo control in stability. Any ideas what could be causing this? At first I thought the canopy so I took it off and the problem remained. I also have the microheli frame.

Check the feathering spindle. Even a slight bend will make flying a nightmare.

hold the heli in your hand by the tail boom mount, is it butter smooth in your hand or does it have violent vibrations with the blades on vs with blades off?

The feathering shaft was bent thx. I replaced it and most of the wobble went away but not all. Well a crash or 2 later the main shaft broke so I suspect that was a little cracked before too. Thx for the help.
