Well Bob, every time I think I'm ready to fly this plane, something stops me out of worry that I'm going to blow up this "now controversial" airplane. Today was to be the maiden flight and it is windy in AZ. Pulled out the razor blade and took off my bottom aileron covering like you. I found from another thread (dual aileron servo mod) that there are two versions of the ailerons out there. One has the diagonal ribs and the other doesn't. Mine doesn't so maybe my version is the problem child. I found that a lot of glue holds the trailing edge sheeting together possibly pushing the aileron CG back to extremes. I noticed that there are upper and lower spars along the front sheeting and a nice place to glue vertical grain shear webbing to make a nice spar box in the LE (helps CG too). That webbing surface makes a nice face for the addition diagonal ribs. I think I will also add a corner gusset (like the cap strips)over the diag. ribs and see if that helps. The aileron sure becomes flexible when the covering is removed. One day I'm gonna fly the hell out of this thing.
