@XDAndy sounds like you might have bent the main shaft-rotors slightly off set-let us know

Hi
Just got me one of these amazing little machines, but finding I'm having a problem.
After bouncing off the ceiling, the forward motor popped out of its socket.
After carefully replacing it, I'm now having the issue where the copter may start to vibrate with a rough sounding noise coming from the gearing and a loss of altitude.
No obvious rotational issues with this.
Increasing power seems to bring i back to life, roughness sound goes away, and altitude rapidly increased, but then reducing power to bring into stable hover, then process starts again and altitude lost when the rough sound returns.
I think the issue is that there's a problem with the gearing and one of the motors is starting to slip, but all the teeth look fine, there doesn't appear to be any slack, and the motors both look secure.
Was wondering if anyone has had a similar problem, and if so, did you find a correctable cause?
Thanks.
Andy
