After much struggling with the left-side aileron belcrank and pushrods, I decided to switch to the right side. I made a larger cutout in the C8 rib, and I made up an aluminum pushrod for the belcrank-to-aileron segment of the control system. I am still using a wooden dowel for the control stick-to-belcrank segment of the system. and I am also still using an un-riveted belcrank because of the probabiity of need for adjustments. with these changes, I am now able to achieve 20 degrees of upward deflection and 15 degrees of downward deflection, as called for in the plans. While there is still a long way to go in this area, this was a great step forward. A few of the next steps include: 1: bring the left side up to the same level as the right side. 2: fabricate final belcranks in the new shape according to original materials spec., paying particular attention to interface between belcrank and aileron stop angle. 3: analyze proportional up and down deflection with both ailerons connected 4: determine needed lengths of all four pushrods and fabricate from aluminum tube 5: fabricate two new center section ribs, for positions C 1.5 and C 7.5 6: debur and smooth the newly enlarged cutouts in ribs C 1 and C 8 7: design doubler pieces to reinforce ribs C 1 and C 8 because of enlarged cutouts 8: review plans to determine original design intent regarding reinforcement of step area, and see if the changes above call for different reinforcement approach.
