WING INSTALLATION
❏
1. Set your lower wing in position over the fuselage
and tuck the extensions into the fuselage. Locate the wing
reinforcement plate and the plastic wing bolts. Bolt the wing
on with the reinforcement plate in position.
❏
2. Trace the outline of the reinforcement plate onto the
lower wing.
❏
3. Remove the wing and trim the covering 1/8" [3.2mm]
inside the line you traced. Peel off the covering so that the wood
is exposed.
❏
4. Lubricate the threads of the wing bolts with petroleum
jelly. This will keep them from being glued in place in the next
step. Mix up some 30-minute epoxy and thin it down with
several drops of denatured alcohol.
❏
5. Set the wing back in position and connect your aileron
servo leads in anticipation of the next section. Apply a thin
layer of 30-minute epoxy to the bottom of the reinforcement
plate and set it in place. Glue the reinforcement plate in place
by lightly snugging down the wing bolts. As a precaution,
you can loosen and re-tighten the wing bolts in 15 minute
intervals until the epoxy sets.
❏
6. Locate the two (2) interplane wing struts, two (2)
4-40 x 3/4" [19mm] bolts, two (2) 4-40 self-locking nuts, and
two (2) #4 washers.
❏
7. Identify the top front of each wing strut – look for the
small lightening hole behind the covering. You may want to
mark these with a felt-tip pen.
❏
8. Install the interplane struts to the bottom wing fi nger-tight.
