yeah TINY screws.. not sure i have anything small enough to unscrew them. Oh wait, just realized I was looking at the screw end not the head! Took off the servo from the wing and I think I can get them out. The servo managed to recenter itself, but it will only move if i give the gear a little roll by hand, then it loudly wretches into position, like something is binding in there.
