This can be: slightly bent hub of the tail rotor, jammed or defective ball bearings, tail blades / tail rotor is not properly balanced, engine bell not balanced / comes at a certain speed to vibrate or motor bearings damaged making the motor shaft vibrate, slipped ball bearings in the torque tube tail drive system or installed in the wrong position, main gear wobbles / unbalanced; motor shaft bends and runs rough, ... actually everything that rotates on the helicopter can be the cause of such a vibration. On electric helicopter you normaly should not hear, feel or see any mayor vibration (no vibrating tail fin or skids). Then it should normally be possible to attach the Microbeast only with a very thin adhesive pad on electric helis.
