Brief Description:  Rigging ailerons

Spent entire day rigging ailerons for proper travel. Opened control stick hole toward the pilot side in order to get full control stick deflection. Also, noted that upper bell crank inside of keel was striking the top of the keel during left deflection. I cut a small slit in the top of the keel so that bell crank would be able to travel its full lenght.

I found out the proper way to adjust the ailerons was to first adjust the tie rod ends at the whale tale. The trick is to adjust them such that each push-pull cable gets the full travel of the limiting "throw". The pilot side has a throw of 3 1/2 inches and the CP thow is 3 1/4 inches. Therefor the limiting throw is 3 1/4 inches. Each of the tie rod ends in the whale tale so that the travel on each side was 3 1/4 inches. Now we leave the whale tale alone and adjust the tie rod ends at the wing root.

The wing root tie rod ends were adjusted so that the neutral aileron position resulted in each aileron "sagging" about 1/8 inch below the faired position. ( Air loads will bring them up). Full down travel resulted in a 2 1/2 inch deflection. Control is a little stiff, but smooth.
