Check the gear mesh/main motor pinion, make sure it's not too loose or tight. Make sure the flybar paddles are correctly aligned. Make sure there's no excessive gap between the rotor head and the blade grips....all I can think of right now.

Well I'm ready to hover but can't get a calm day. Everything is ready I even went so far as to buy new blades. One problem now comes up. I balanced the blades and whe i mount them and spin up there is a bad vibration. I checked and adjusted tracking. still vibrates. I took the blades off and spun up the fly bar with the paddels and it was smooth. So can I assume it's in the blades? If so other then balance what should I do. If it isn't the blades then what should I look at?
