Hi,

I am strugling with a wing design, i have designed wing, then cut out the aileron, made a servo and a connecting rod. However, when i connect the aileron and servo i get a complete movement of aileron and not about the leading edge of the aileron (i.e. the entire aileron rotates as i move the servo arm) - I have tried angle mates but it only limits the amount of movement by the aileron and does not make it rotate about the leading edge.

any help ..does anyone want to see the cad file ?
