The wings are attached using a 6mm nylon bolt and spring clip. The first few times you
install the wings, the holes for the spring clips will be tight to the fuselage side. This is
by design, use a small tool to clearance this fit before installing the clip. After a few
cycles this will settle in at the proper clearance.
Optional wing tip accessories. Installed using #4-40 screws. Use the spacer to make
sure that there is a gap between the SFG and the aileron to eliminate the chance of
binding.
