Hye guys,

I am getting my CPP back in the air after it had been sitting for a bit. When I throttle up, it is good untill about 20%. Then the heli begins to vibrate very badly, and I am forced to throttle down.

I have checked the blades- perfectly balanced.
The spindle is perfect.
When I run the motor without the blades, there is a small vibration in the head- but not much. Once I throw the blades on, it is real bad.

I think I might go to the store today and get a new main shaft and main shaft bearings. Any ideas though?

Thanks
