ar7200bx idel up vibration

[u8at711]

posting this for a friend,

he has a mikado 500se with 620 blades

ar7200bx,

when the head speed is 2000 rpm everything is smooth,
once he goes into Idel up with a head speed higher than 2000 the heli has major vibes.


I don't have any flybarless experience, so I can't help.

is he using the stock gyro tape? if so it needs to be replaced, it's too thick and allows the 7200BX to 'float' around. also make sure the wires going to it aren't so tight that they transfer vibration to the unit and lastly, it could be something on the heli (out of balance, bent, brg going out, etc.....)
