3. Use 6-minute epoxy to glue the two 3/8"
[9.5mm] diameter forward wing dowels in the
leading edge of the wing. The wing dowels should
protrude approximately 1/2" [12.7mm] from the
wing. Also glue the 1/4" [6.4mm] aft root rib guide
dowel in the left wing half. Clean off any excess
epoxy before it cures.
❏
4. Once the epoxy has cured, remove the clamps
from the wing joiner and sand off any excess epoxy
you may have missed. Test fi t the wing joiner in each
wing half making sure that both wings halves fi t
together at the root without any gap. Trial fi t clamping
the wing together with rubberbands around the wing
dowels and the trailing edge.
❏
5. Remove the rubberbands and separate the wing
halves. Remove the wing joiner. Mix 2 oz. [59.1cc] of
30-minute epoxy. Working quickly, pour a generous
amount into the joiner pocket of one wing half. Use
your wire or dowel to thoroughly distribute the epoxy,
coating all surfaces inside the joiner pocket. Coat
the root rib and one half of the wing joiner that goes
into the wing. Insert the joiner in the wing. Proceed
immediately to the next step.
❏
6. Coat the joiner pocket in the other wing half and
the other end of the wing joiner. Join the wing halves
together. Then, stand the wing on end with one of the
wing tips resting on the fl oor. Use a piece of R/C foam
or something similar to cushion and stabilize the wing
so it won’t slide around.
❏
7. With the wing resting on end, use paper towel
squares to wipe off any excess epoxy as it squeezes
out. Wrap the rubberbands around the wing dowels
and the aft end of the wing. Add several strips of
masking tape to tightly hold the wings together as
you continue to wipe off excess epoxy as it squeezes
out. Be certain the leading and trailing edges of the
wing accurately align. Do not disturb the wing until
the epoxy has fully cured.
Perform this step only if you have installed retracts.
❏
8. Join the matching air lines from each wing half
with a couple of T-fi ttings that came with the Robart
air control kit. Cut two 10" [254mm] pieces of air line
(also from the control kit) and fi t each line to the
T-fi ttings. Connect one quick-connector with an O-ring
to one of the air lines and one of the quick connectors
without an O-ring to the other line. This will prevent
improper connection to the quick-connectors on the
air valve when mounting the wing to the fuselage.
INSTALL THE FIXED MAIN
LANDING GEAR
If you have installed the retractable landing gear
proceed to ASSEMBLE THE FUSELAGE.
❏
1. Place both fi xed landing gear mounts on the
landing gear plates. The mounts are the same, but
the part with the straps goes towards the leading
edge of the wing. Using the holes in the mounts as a
guide, drill six 7/64" [2.8mm] holes into the landing
gear plates. Attach the landing gear mounts to the
landing gear plates with fi ve #6 x 3/4" [19.1mm]
sheet metal screws and one #6 x 1/2" [12.7mm]
sheet metal screw.
