fixed wing single aileron setup on CC3D. on manual mode  everything is stable. but when turned to attitude mode the ailerons flutter [vibrate]  when the throttle is  operated.. any ideas on how to stop aileron vibration??

This happens on the ground without even flying?  CC3D for sure or "Revolution" which is stupid cloner name for Revolution.

Output page outputs should all use PWM@50Hz

PIDs may be too high

Remove prop and test again.  If problem goes away, balance your prop better. 

Have you made changes by using the System page?  Some of those settings are somewhat "expert only".

Thanks Cliff.. Spot on. Prop slightly out of balance and even though the motor was tight on the mounting the motor mount had movement. Balanced the prop and tightened the motor mount and  i seems to have fixed my problem. Test flight tomorrow...THANKS CLIFF
