Hello I recently got a Walker Dragonfly X-Rotation #5C V3 + Camo Fuselage and ran it a few times and now all of a sudden it shakes around when powering on the main rotors and in the air. I know this is because of something being unbalanced and started looking for it while using process of elimination. I found by taking the top rotor off, shaft and all, and powering on the lower rotors, the carbonfiber shaft above the lower rotor was wobbling pretty bad. I don't know if the shaft that powers the top rotor is bent too though? Is there anyway to fix this or should I try to get new parts? I have the part numbers in the manual, but where would you buy new parts for this particular copter? Any help would be much appreictiated! Thanks

Hey woodymaxx,

One thing you could check for, is if the ball-links that connect the flybar to the top rotor-head are still firmly in place. In my experience, it doesn't take much for them to pop off at the top, in which case, because of the way it's constructed, they remain attached to the flybar through their holes, but can move freely and will be out of alignment.

I've never bought from them before, but they seem to have all the parts.....

It's very likely the fibre carbon shaft is distorted and at the end of the fibre carbon shaft where the upper maingear is mounted is damaged. It only takes a few strikes of the lower blades before the carbon shaft is distorted and vibration starts. Replace the fibre carbon shaft will solve the problem. Don't waste your time to balance the helicopter. It's not nessessary.

well now that I have put in the new carbon fiber shaft the woble went away, but now the gears make a bad grinding noise and the lower rotor stops coasting bfore the top after i turn the rotors on and off. The grinding noise is only made when it first spools up and really happens when you turn them all the way off. But other then that it sounds normal between that. This in turn has made the heli pretty unstable. it seems to go where it wants... any ideas? thanks

any Ideas yet?
