This numerical approach is fast but not without drawbacks. Lack of convergence due to boundary layer separation is a common problem and prevents us from getting any result when it occurs. It is more pronounced in high angle of attack and high angle of con

I cut my ailerons the same way you did and used Duck brand packing tape for the hinges. I mounted my servos on their sides instead of vertically so that their arms rotate around an axis parallel to that of the control surfaces, to minimize binding. I also

Note that the ends of the ailerons need to be trimmed to allow for full motion about the hinge, as shown in the image below: Step 6 — Glue the Frame Use normal white glue (ex Elmer’s) and spread the glue over the entire surface to be glued using a fla
