Last weekend I had a JR 811 on my throttle with a GV-1 and stator gator on my p gasser, and it failed on me, in flight, just stopped moving while I was over half throttle. Luckily I was able to get it down safely after it ran out of gas.

This week I put on a longer boom and 800mm blades, along with an 11t pinion, and a new 9252 servo on the throttle. In normal mode, it was running sweet as I've ever seen any heli run, but when I put it into idle up 1 or 2 (1150 & 1250 headspeeds) it got what I guess is described by many as the wahwahs. Basically the throttle would just jump up and down quickly, it never smoothed out like it ran in normal mode.

I've searched around and can't find anything about this happening on a gasser with a servo that's too fast on the throttle, but wonder if that could be my problem?

Thanks!

Did you reprogram the GV-1 after you changed the servo?
Sounds like you just swaped the servos.
Even if using same endpoints and servo arm,you should set up GV-1 again ,after changing the servo.

I considered that a given, but thanks for pointing it out in case I had forgot.

Same thing happened to me, suddenly the throttle goes up and then the governor is no more in control, governor was working ok on low headspeeds but when I was going for 1250 or 1300 had that problem. I solved the problem icreasing the ATV on both sides, they were in 100, put them to 120,. And adjusting mechanically the throttle for a linear response was also very important to me.
