Hey guys...thanks for the great suggestions and ideas. The airplane is laying on it's back on the bench, and there is no part of the tail that touches the ground. (or anything else for that matter)
When I get home I'll have to make sure that the wires aren't hitting anything inside the fuse. I'm pretty sure they aren't, but hey...
Also...The servo sounds fine everywhere through it's range except when it is released...It's like it has a problem centering.
When I release the rudder/throttle stick, the servo will hum loudly for a couple seconds and then eventually center and shut off.
My NEW thoughts (hahahah) are
1) Friction along the setup somewhere (servo arm, wires rubbing the fuse, etc)
2) Would a low battery cause this? I was using my bench battery...???


To answer some of the questions...I'm not entirely sure if the cables are the same tension....how perfect does this have to be?
The servo is a brand new HS645MG. Not a digital servo, but tough.
The flight pack is a 2700mAh NiMH 4 cell flat pack.
The servo sounds fine all through it's motions, and only hums near center, OR sometimes when it is held in position, although I think that is normal.
Again...thanks for all the help.
