Any body has an idea
What is happening, I wil try to explain. Already at spool up there is a very high frequency vibration which already is shifting the heli of my landing platform (during complete spool up, so not the vibes at certain HS).
Whith flying I don't see it (and actually flies good) ,but I know its there (also my logs show a lot of extreme vibration levels)
What I have done sofar :
replaced all bearings, replaced complete main block incl bearings
replaced the complete tail section
blade tracking (tail and main blades)
replaced MG and tail gears
replaced mainshaft
I have completely no play in tail or head
all runs very smooth tail and main drive train. But I am actually little out of options at the moment
it is a 450pro with fbl head (no DFC)

If it is not clear I can make a short video.
