Ive got my TRex assembled trimmed and balenced so i thought. I gave it a few hours of test flying. When ever i start up the rotors i have a bad wobble until it reaches speed then its fine. I got the blades to track right on so the side view when spinning is perfect. I was also having gyro problems. i cant seem to get a stable profile in the air my heli always want to bank to back left then spin out. I checked for servo slop and can find none.

I also balenced the blades according to the Trex manual with the bolt in the middle of the two blades together....seemed to be perfect.

I asume the the heli should balence when hanging from the main rotor head and not be tail heavy...mine is slightly..


excuse my lack of knowlwege i am an airplane man. just trying the EP heli's out.

if a gyro is working correctly and set up right a heli should pull start up in the air and not rotate <--- i asume

I also got my T-rex setup recently. I had the same wobble problem, and what I did was tighten the main blade a little more. The wobble went away, but the blade went out of track at different pitch setup. I used Teflon tape to stick around the rubber parts of the main blade holder, and it worked perfect. I hope this helps you a bit. Have fun.

You tightend the allen head screws? The ones that hold the blade grips? My trex came with little rubber grommits i think 2 per bladegrip for the gap you filled with teflon.

Yes, the allen head screws that hold the main blades.
