Bill,
Not many screws, just small nails or brads (better to mash your fingers with). The few screws I've seen have been for the internal wire bracing or what look like 1/4 x 20 screws (with blind nuts) for the aileron hinge or strut/fuse connection parts. I think 2-56 screws and nuts would work just fine. I belive Micro-Mark has the tiny screws and or brads.
