Stick,

I evidently have one of the older models, because mine does indeed have a metal throttle arm. All of my others have plastic. I'm definately going to start there. There's been talk of maybe having a cracked crystal. It is a brand new, never used crytal/receiver. It could still be defective, but I doubt it. Once I get rid of the metal contact at the throttle arm, I'll give the crystal a try if I haven't gotten the problem fixed.
