- Thrust bearings in the rotor head installed properly (not reverse)?
- Radial bearings in the head not damaged? -> change them
- Bearings in the blade holders are moving -> loctite the bearing or replace blade holders, or buy 'upgrade' metal blade holders
- Grease the dampener rubbers, this has prove to cure some woof and poof on raptor 30v1
