Rigging the aileron cables turned out to be difficult. The aileron deflection up and down had to be in the specified arc from the Glasair manual. Plus, that had to occur when the control sticks were centered. We devised plywood wedges to lock the aileron cross tube in position. This became a back and forth job of adjusting turnbuckles and measuring the up and down deflection of the ailerons using our digital angle gauge. And also we found that when the ailerons were properly rigged, they did not exactly line up with the flaps.
