The kits prior to this one are copies, almost identical to the original, of a wing; I make a tracing of the wing outline with aileron location / tube / adjuster / hold on locations...., make a tracing of the root rib and then transfer the information into AutoCAD. After that is drawn I then locate the ribs and spars and draw all the pieces for the wing and jig. I then repackage the ribs and spars for the laser cutter, AK Models in Iowa, and he cuts the kits for me.
