[QUOTE=Jim.Thompson;12247263...
It is running the best it ever has now with both needles fully closed! ...
The elevators are vibrating at an alarming rate and at a large magnitude; I suspect that this is working the servos hard and draining the batteries....[/QUOTE]
IMHO, having to run any engine with both needles closed does not indicate the problem is fixed. Re the servos jittering seems to me to be either a radio issue or that the spark plug cap is not fully seated. Is it? Probably addressed before, but has this engine ever run correctly with the needles set to nominal positions? What have you done since then to make it not run right?
