In reply to both,

No, I don't have an on-board glow. I usually use a nylon clevis, but in this particular incidence, I didn't have enough room for one. I think I have figured out a way to run my throttle pushrod so that have room for a clevis. It (pushrod) definately isn't hitting the side of the engine. It is affecting all channels, not just one. Even on the ground, when I go to WOT, all of the control surfaces jump, even the throttle is affected. Once I come down to around 3/4, or even 1/2 throttle, all of the irratic movements stop.

I plan on changing my throttle linkage arrangemet and adding nylon, and changing the metal wing bolts to nylon. That will do away with all metal to metal contact in the plane. i'll also check all of my connections at the receiver, but I really don't think that's the problem.

Thanks for your input guys,

John
