I manage to fix her all day today. First I did change the shaft 3 times. Second change the stock tail blade to carbon. Third change the boom and tail support. Then a funny sound then I set her down, motor is kinda hot. So I redo all the tail again then I notice the belt is twisted from the middle. Oh I put a shim in between the tail grips and the hub, one in each side. Well I almost did the whole tail assembly but vibration is gone.

The vibration is not very noticable untill I flew next to my face. And it does not affect the flight. So I just want to twick it a little coz I want to do something today.

I conclude that sometimes I nick the rotor on tail-in landing. Its not a tail strike coz its very light touch. Maybe thats the culprit, a little tail nick. Hope this help someone out there.

Yeah, in the three hovers I have managed so far on one the heli rotated slightly clockwise as landing and the tail fin bent in the way of the tail rotor - resutling in one ever-so-slightly bent tail rotor shaft :(
