I can't get my Trex 450 to stop vibrating. I rebalanced the main and and tail blades, I put a new high carbon main shaft into it, I checked the tail shaft, it dosent look bent at all. Anybody have any more ideas?
Vibrations are always a booger to find...
Sometimes bad main bearings can also cause vibrations, along with lots of other stuff in which where it could be coming from... Are your paddles at equal distances, flybar equal and centered ? You could slip off the belt temporarily, and then spool up the mains to see if the vibration is in the head area.
Have you taken off your main blades and spooled it up to see if there still is a vibe issue also ? How about a short video to help show ?
