04/07/13 - Aileron Bell Crank Rib Brackets
We mounted the two vertical C shaped channels behind the aileron bell crank assembly. There are little right angle peices that connect these channels to the skin. All this extra structure is to stiffen the rib where the bell crank is. The plans show to make the top face of the angle peices flush with the curvature of …
