I've spend the last couple of days tweaking with the aileron system.

I thought I had the aileron system pretty well rung out, but while I was under the right wing manipulating this back and forth, I noticed an ever so slight rubbing sound at full left aileron deflection. It sounded like a wire rubbing so I started with a visual inspection of the wire bundle where it went into the roll servo, but that was well secured and out of the way.

It took a while to chase this down, but eventually I discovered that at full deflection, the outboard right aileron hinge was just ever so slightly rubbing against a rivet tail on the aileron bracket. I changed teh washer stackup to move the aileron inboard the width of 1 washer, which is about .060 and that cleared the rubbing. I may give this another look later and see if I want to move both ailerons inboard another .060. That will leave me with about a 3/16 gap between the ailerons and flaps, while the plans call for .25.

That doesn't seem like enough to negatively affect anything and I sure don't want there to be any possibility whatsoever of the ailerons rubbing on anything. An alternative may be to make sure the offending rivet tail is set correctly and not sitting proud. I'll revisit this later.
