Gaui 425 shaking help

[Davy Crockett]

I need some help please with my 425....

A few weeks ago I had a minor crash, checked everything and replaced main shaft, feathering shaft, flybar and main blades.

Blades are balanced, nothing is bent but she shakes like mad, so much that when off the ground you cant read the lettering on the skids

Have I missed something or done something wrong in the setup because I am stumped

any advice or comments would be welcome

I'd check the tail hub, grips, and shaft. I chased a vibration for ages on my TT360 and after replacing everything it turned out to be a bent tail hub.

I have found part of the problem....

I had put the thrust bearings on the end of the feathering shaft instead of inbetween the 2 bearings

maybe I should learn to place things in order when I take them off the heli
