1. Modified the wing tip riblet (mounts aft of the hinges) to fit the wingtip.
2. Counter-sunk the area where the hinge rivets are located. Riveted hinge to wingtip and then epoxied over the rivets on the top of the wing encasing them.
Spent a lot of time on the left wing as I had to figure out how all this would go together. The right one should go much faster.
