No biggie I have a little over 1 inch on mine and had to do what I mentioned in my earlier post to get that kind of throw. (longer arm, control horns near the top, etc...) and that is all she will get. I had moved the horns down to the middle of the rods and had the same problem with the clevises popping loose even with the fuel tubing as backup. If I try to get more the lack of beveling on the wing TE or aileron LE will not allow it and they start to bind.

I believe that may be the problem here but we need pics or a more detailed description
