mrasmm - Thanks again for more tips. I will give that a try tomorrow. That should fix the vibration I hope.

DY - Right now the idle up curves 1 and 2 on the DX7 are not fully programmed yet. I have been doing the mods mentioned above, plus getting the swash programmed with the radio took a little longer and then I had to adjust the mechanical links with the new radio setup. What I can probably do fairly easy is bench swap the radio back on temp basis - minus rudder (every minute in the tail motor is important) and crank up the throttle while holding the heli - blades facing away of course - to see if I get the same kind response I get using the DX7.
