You are right, it was essentially in tension. But, the heads tear off so easily, I was very unhappy. I repeated my simple test with A5's, and the ball end pulls through, but the heads do not pop off. This to my mind is ok. The rivets themself don't just break in half. Regards, Jeff Jeyoung65(at)aol.com wrote: > Jeff, when you tugged on the strip, what angle were your tug with the clamped piece? Or, was the rivet in shear or tension. Would expect the rivet heads to pop off if your tug was 90 degrees to the clamped part but if it was 180 degrees then there is a problem.

What force would that primarily be, tension or shear? Tension, correct? That large gap between the aileron and wing always looked funny when parked in a car next to the aircraft. Could it be that since the gap is no longer sealed by the hinge-less aileron skin, some sort of turbulence or pressure is created between the forward edge of the aileron and the rear spar, causing this flexing? The fact that the flexing is only noticeable at the inboard or next rib and not the outboard ribs seems to indicate that the control rod has some influence on the action.
