No form of control binding is acceptable.

1-I disconnected at the outboard end.
2-Stops are installed and deflection is within spec.
I just got off the phone with Van's. They said if there is an issue with the heim joint touching the weldment it's most likely at the control stick end. They said there are very small washers that are added between the joint and the weldment to alleviate this issue. I remember installing these washers because they are such a pain but I will double check anyway.
He was also saying that if this is an issue he's know people that had to relieve the weldment a bit to clear the joint.
I won't be able to get out there until Tuesday but when I do, I think I will:
-Move the stick as it is now with the outboard ends disconnected to see if the stickiness is there. I don't remember making that check over the weekend. Of course the geometry will be different than when they are attached so I'm not sure how much this will buy me.
-Then I will hook up the outboard ends and disconnect at the sticks then move the ailerons to see if it is gone.
-At some point I was thinking of loosening the heim joints, take the ailerons to their limits, then tightening the joints at that point.
The guy at Van's actually went out to check on their birds and he said that, at least for the one he tried while I was on the phone with him, there was a small bit of stickiness at the extremes.
Some things we were kicking around over the weekend were maybe the mechanical advantage of the bellcrank is less at the stops (confirmed by Van's) and the airloads will make this a non issue in flight (also confirmed by Van's). Van's said this is not a safety of flight issue.
Regardless, I'm with you on this Dan, I want to chase this down and get it cleared up. I want my controls like butta at all extremes if that is possible.
Regarding rivets, I checked those and they seemed to clear.
I'm thinking I'll find the smoking gun during the "twizzle" check but we'll see.
I'll send out an update later this week. Thanks again for all the help.
