16. Find the four white nylon anti-rotation pins. Locate
the holes in the wings for the pins. Mix a small amount of
30-minute epoxy and glue the anti-rotation pins in place.
Once inserted the pins should stick out about 1/2" [13mm].
Clean up any excess epoxy with a paper towel dampened
with denatured alcohol.

17. If you have not done so, go back to step #1 and finish
the left wing the same way.
❏
1. Feel through the MonoKote for the wing mounting holes
in the fuselage. There should be a total of six holes on each
side of the fuselage: two for the wing hold down bolts, two
for the anti-rotation pins, one for the wing tube and one for
the servo leads. Cut away the MonoKote and seal the edges
with a sealing iron or a trim seal tool. Remember to do this
on both sides of the fuselage. Note: A little bit of thin CA
applied all the way around each hole will protect the wood
fuel creep.
❏
2. Even though this step belongs in the “Install The Tail
Surfaces” section, it is more convenient to perform it now.
Feel through the MonoKote for the stabilizer slot in the aft
part of the fuselage. Cut away the MonoKote from the slots
on both sides of the fuselage and then seal the edges with
a sealing iron or a trim seal tool.
❏
3. Find the aluminum wing tube and install it centered
in the fuselage. Test fit the wings to the fuse and bolt them
in position using two 1/4-20 x 2" [51mm] nylon bolts and two
5/16" [8mm] wood washers for each wing. If necessary,
enlarge or adjust the wing bolt holes in the fuselage so the
wing bolts will align with the blind nuts in the wing. Also,
slightly enlarge the anti-rotation pin holes in the fuselage if
necessary. Slightly enlarging the pin holes does not change
the wing incidence. Install the two wings this way. Cut 1"
[25mm] off the end of all four wing bolts, this will make
installing the wing easier. Remove the wings from the
fuselage.
❏
1. Glue a 1/2" x 1/4" x 8-1/4" [13mm x 6.4mm x 210mm]
hardwood stick to the servo tray as shown with 6-minute epoxy.
