Found the problem, the main shaft was crooked slightly where the slider hole is and cause the rotor head not turning true, there's no noticeable wobble but may be some resonance at the lift off rotor speed (2300 rpm in this case). Another problem shows up, the heli used to hover very stable and pretty much can "hold it there" hands off for couple seconds, now she's going up and down and very sensitive in the pitch/throttle control, we're flying in the idle up mode, the motor speed is at 100% throttle. The only changes is the carbon blades since the PE blades were destroyed, they are the same size, hovering pitch is at about +6.0 - 7.0 degree.
