edge of the wing. Tighten both wing bolts at this time to
secure the wing to the fuselage.
5. Repeat the previous steps to install the remaining wing
panel.

SIDE FORCE GENERATOR INSTALLATION (OPTIONAL)
1. Remove the covering to expose the pre-installed blind nut
in the wing tip using a hobby knife equipped with a #11
blade.
2. Thread a 6-32 x 3/4-inch button head machine screw into
each of the blind nuts. Clean the threads using a 6-32 tap
if the screw does not thread in easily. Remove the screws
before proceeding.
3. Apply a drop of canopy glue on each of the 6-32 x ¾-inch
button head machine screws to keep them from vibrating
loose, yet still removable. Attach the side force generator
to the wing tip using two 6-32 x 3/4-inch button head
machine screws and two #6 washers. Use a 3/32-inch
hex wrench to tighten the screws.
