I have a blade 450X that started vibrating severely at high head speed. It vibrates at lower head speed but more like the tail bobbles up and down. So...I think maybe main head? Checked and replaced the main shaft and feathering spindle. Replaced tail hub. Checked the tail shaft. All good.

Any typical problems with this critter? Does tue headblock bend easily? It just showed up on one flight. Never hit anything or bumped anything that wpuld cause a bent part. So. I am stumped.

Back to it!

Did you replace the dampeners with the spindle shaft?
