Finish the bottom of the wing
Refer to this photo for the following three steps.
❏ ❏
1. Cut three 1" long flap hinge blocks (only if
you are building flaps) and three 1-1/2" long
aileron hinge blocks from the 1/2" x 1/2" x 6" balsa
sticks. Glue the hinge blocks into position. Note that
the aileron hinge blocks are
centered, height-wise,
on the outer TE spar and that the flap hinge blocks
are
even with the bottom of the outer TE spar.
❏ ❏
2. Glue the die-cut 1/8" plywood control horn
plate into the notches of the aileron LE spar and rib 8.
❏ ❏
3. Cut the aileron servo hatch rails from the
remainder of the 1/4" x 3/8" x 36" basswood stick you
used for the forward tank mount tab. If you are
building flaps, cut the
flap servo hatch rails from
the same stick. Keep the rest of the stick for the aft
tank mount tab. Glue the rails into position.
Return to page 28 and repeat the process for
building the left wing panel. Don’t forget to build
over the left wing plan!

❏
1. Cut the center out of rib W-1 on both wing
panels. Make a half-round groove in the center LE
block in alignment with the slot in W-1 to
accommodate the wing dowel.
❏
2. Test fit both die-cut 1/8" plywood forward wing
joiners in both halves of the wing. Make adjustments
where necessary so the joiners fit half-way.
❏
3. Without using glue, test join the wing halves with
the forward joiners. Lay one of the panels flat on the
❏ ❏
F22. Glue pieces of leftover 1/4" x 1/4" or
3/16" x 3/16" balsa around the fixed LG plate (but
not to it) to support the sheeting after an opening
is cut for the plate. Remove the plate, then sand
the sticks even with the rest of the ribs .
❏ ❏
F23. Take out all the screws and
disassemble the landing gear assembly. Add a
few drops of thin CA to the holes in the LG rails in
the wing and to the holes in the grooved landing
gear mount.
❏ ❏
F24. Enlarge the hole in the wheels with a
or #9 (or 13/64") drill so they will fit on the landing
gear wires.
❏ ❏
Test fit the wheel to the landing gear with a
3/16” wheel collar on both sides. File flat spots
where the set screws of the wheel collars lock
onto the gear.
