Hiy,
I have the same problem with my belt. When I fly it is as if the main-shaft moves in a cone shape way, with the tip at the bottom. I have also noticed that if increase altitude very rapidly and decent a few times that the wobble goes away, its like an on purpose chicken dance :roll:
Every thing is balanced and straight....
Can anyone help us?

try checking the one way bearinb and make sure its set right in the gears or that nothing is between the two gears whitch would make it see as if the rotor head is off balance.
