I fit the servo hinge and drilled the upper side forward and aft servo tab spars. I did come up with a good way to lay out the rivet pattern. I saved the skin cutout and used the pre punched holes in the training edge. I first drew a rivet line and lined up the holes. I had to flip it over to get good spacing on the inboard and outboard ends of the pattern. This worked well for both forward and aft spars.
