Raptor E700 Vibration

[Speedy]

Hi spirit,

at my Raptor E700 the vibration level for main rotor is very high. Any idea what the problem could be?
This vibration level is very high for main rotor or isn't it?

It is not my first helicopter that i build and fly. I always thougt when i look at the main shaft that the rotation is not correct.
Maybe i change the main shaft first.

Regards
