Hmmm Ok, Bill. That's something to put in the notes section of my next book!!!

just kidding.
Servo/control surface problems can come from a lot of things, many are not the usual problems we face with glow power, as you so well pointed out.
What's tough is the way the smaller electrics are constructed.. with really flimsy - light-weight control rods that really need care when working with them. Add to that what you found, well, you can end up with a real problem child. Hope that clears up his problem. Sounds reasonable.
I have one of those XPD8's that have the electronics in a small compartment on the top, under the "canope". Not a lot of room, and the servos are mounted in a sort of wierd position on the side of the fuse. I have not flown it yet, but I imagine that this thing would be one of those prone to strange problems too. That's one solution I will have to keep in mind when I play with that beastie.
