I cleaned up the inside of the tips where I had bonded the backing strips. Lightly sanded to remove the sharp edges. Next, I replaced the temp nuts on the back of the Aeroled mounting brackets with some #6 elastic nuts. I ran the retaining pins thru the hinges—well most of them. I found one eyelet that had some dried resin blocking the pin. I picked at it with a paper clip until I got it cleared. Then, I installed the wing tips onto the wings. Some of the pins are pretty tight toward the last few inches—maybe Boelube will help. Calling the tips done—at least for now.
