wollins,
Sorry I didn't see your post. Yes, the pushrods that were supplied were too short. I picked up a couple of longer ones at the LHS for something like 75cents each or something like that. The ones that're threaded 2-56 on one end. You find them in bulk in a tube in a display. Almost all my pushrods have the metal solder clevis on one end and screw-on clevis on the other. That setup gives an almost bulletproof connection that fits both ends with no "twists" and a straighter run.

opjose,
Interesting "paint" scheme on that green/white airplane. Ozark hasn't been around since????? Truth is, the lower connection design on that airplane is somewhat closer to being "square" than a lot of them and wouldn't cause too much differential. When the biplane has positive stagger the connection that causes the most differential is the upper one. It's absolutely amazing to me that the plane in the lower picture is almost a standard example of the usual rigging. It would seem that at least one or two of those "designers" would actually look at how that rigging works and ask themselves if that was the way the ailerons are supposed to work. I think there is actually an assembly booklet that has a diagram of the correct way to have your pushrods square to servo arms and surface axis of rotation, and then their bleedin' ailerons are rigged just plain dumb and not even close to their diagrams.
