Hello, I have a Benzin Gas Trainer, when I am hovering up to speed its very smooth, but when I land and the RPM's start to come down and as it gets slow, I get a real bad viberation, this just started, wasnt there before, any ideas on what could be causing this? Thanks Tim W.

Sounds like Lead - Lag. Check the tightness of the Blade bolts. If the Blades are too loose they will do this as you speed-up and slow-down.

Thanks Doc, would this hold true with the tail rotor blades also?
