I don't think it's the GG. I tried adjusting it from one extreme to the other with no effect. At this point the T/R is so unstable that if it did make a difference I couldn't tell.

My heli did have a noticable vibration after a light blade strike followed by a slightly bent mainshaft, and the tail did in fact wag, but after I replaced the mainshaft the heli was as smooth as glass. The wagging on the other hand graduated to kicking the heli around 90 degrees or more on its own. I tried adjusting the 3-in-1 board and even hooked a voltmeter to the tail motor to see if the voltage was fluxuating which it did at the lower voltages/speeds.

Oh well, you get what you pay for I guess. It's been so long since I've flown this thing I'm gonna have to start over.[]
