Is this the answer to vibes
I am having a severe vibration problem with my Heli. Vibes go away when I remove the tail rotor blades. One has a small chip in it from ground contact. I will replace it with new blades but I wonder how many folks have had mysterious vibe problems due to almost indetectable diffs in tail rotor blade balance.

Is the shaft slightly bent? Mine bent just a little after a ground strike and I didn't notice it at first.

Sorry, had a few before I posted. I'll be workin on it ini the next day or so. Just wnted to say the B400 is probably sensitive to unbalanced tai rotor blades. Anyone else have an input.

Anything spinning as fast as the tail will show imbalances up.

+1 all-thumbs, If I didn't know that Squiggy Wigginz was joking, I'd think he was not being his usual happy self!
Christmas Cheers to all!

Yes id check that shaft aswell,,I have flown many times with chips in tail blades and no vibes. Also u can consider replacing the 2 bearings that hold the shaft aswell.

Seems when I cane EVER get away with not replacin the tail shaft.. if i even litghtly dust the blades the shaft takes a wipe out.. the slightest bend will cause wag and bearin death.. just the luck i had.. i now have a nice lil supply of them for my 400 and my 450
