Right now I use 2-56 hex head screws with blindnuts inside the fuselage. I epoxied the blindnuts in so they won't pop out everytime I install the belly pan. This way I can use my 2-56 ballend hex driver. Much faster than screws and holes won't wear out. I'll post a few pics later tonight of this mod as well as the mod I did to hold the trailing edge of the wing to the fuselage side.

Later.
