One of my 450s has an insane vibe (almost shaking) up around hover throttle. I put in a new main shaft, feather shaft, dampers and head bearings. Today I noticed the swash has a good bit of slop around that big ball bearing the main shaft goes through. Could that be the culprit? Thanks for any thoughts, Tim

yeah that could be it~ also check your main blades and check if they are properly balanced and also check your blade tracking...

If it's not the blades check the head block. Take the head button off and watch the hole in the top as you spool up to see if it's out of true.

60% of the time, it works every time!

check the tail output shaft to see if it's bent and make sure the tail blades are balanced.
