Yes the thought ocurred to me and it could be that this is the root of the
problem. I made two templates and following buds instructions measured at
the hinge both for up and down ie using the lower surface of the wing
compared to the lower surface of the aileron. So yes I am measuring both
up and down from the same place...the inboard hinge mid point.
Is this correct?
