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 normally 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. On nitro helis the situation can be slightly different as the motors do shake the more or less. This can lead to shaking of the MICROBEAST unit itself and will make the rotor pane wobble. So here trying different pads or a sandwich made of two pads and a metal plate may help to stabilize the unit better. Also the wiring can be the cause of such a shaking. But when the swash tilts as explained above the cause normally is some very high frequent (abnormal) vibration and trying around with different kinds of gyro pads only disguises the real cause and may not help 100%.
