Has anyone come across this before?

When the heli is hovered a wobble in roll can be seen, seems to be getting worse.

Tracking is good
balance is good
its not a vibration, more of a wobble.

The only thing I can find is play on the top rotor mast bearing, although other raptors i have checked seem to have the same play?

Has anyone had this problem?

Any ideas?

had a wobble in my venture, striped down the head and found a collaped bearing in one of the swash arms. Still rotated but was very rough. Could not detect it with the linkages attached.

Upping the rpm will help too, if your RPM is correct at a hover upping it more may mask the problem.

Does the dent in wallet ever equal the dent in the ground?

Head speed
Thanks guys,
Will try upping the head speed, and I thought it was high already.

Unfortunatly my xcell tacho has packed up so cant see what its doing, I will try to get it fixed and post what head speed its happening at.

Thanks again
