30-minute epoxy. Hint: Tape strips of wax paper to
the stab over the TE at the torque rods to protect the
stab from excess epoxy.
❏
4. Join the elevators to the stab and the joiner
wire. Wipe away excess epoxy with a tissue
dampened with alcohol. If the hinges don’t remain
centered, remove the elevators and insert a pin in
the center of the hinges. Reinstall the elevators.
Make sure there is a small gap between the
elevators and the stab–just enough to slip a piece of
paper through or to see light through.
❏
5. Cut a paper towel into several 2" [50mm] squares.
Add six drops of thin CA to the center of the hinges on
both the top and bottom. Use the paper towel squares
to absorb excess CA from the hinge gap.
❏
6. Use the same hinging method to join the rudder
to the fin and the ailerons to the wing. Excess CA
can be cleaned from the hinge gap with CA
Debonder (GPMR6039).
Now hinge the flaps...
❏
7. If you’ve built working flaps, use a toothpick to
apply a small amount of petroleum jelly to the pivot
points of the hinges to keep epoxy out.
❏ ❏
8. Each set of flaps (the left and right) must be
attached to the wing simultaneously (while joined with
the joiner wire). Use a piece of wire or a toothpick to
thoroughly coat the holes in one of the wing halves and
the matching set of flaps with 30-minute epoxy. Apply
epoxy to one end of the hinges and insert them into the
flaps. Apply epoxy to the other end of the hinges with
epoxy. Insert the joiner wire into both flaps and join
them to the wing. Wipe away excess epoxy before it
hardens. Move the flaps up and down several times to
make certain all the hinges are in alignment. Allow the
epoxy to fully harden.
❏
9. Join the other set of flaps to the wing the same
way. After the epoxy hardens, move the flaps up and
down to check their movement and free them up
from any residual epoxy that may have seeped into
the hinges.
Hook up the controls
❏
1. Reinstall the pushrods and install any hardware
and other components not already in place such as
the fuel tank and fuel lines, servos, on/off switch,
engine, muffler, fuel filler valve, air filler valve, etc.
Connect the flap and aileron servos to a Y-connector
(HCAM2751 for Futaba
® servos). One of the aileron
servos may require a 6" [150mm] extension
(HCAM2701) to reach the Y-connector. This will shift
the Y-connector to one side of the wing, but there will
still be enough of the wire coming out of the wing to
connect to an extension on the receiver for
connecting during field setup.
❏
2. Secure connections inside the wing between
servo leads and extension cords with tape, heat shrink
tubing or special clips suitable for that purpose.
❏
3. Slip the wheel collar over the rudder and tail wheel
steering pushrods. Center the rudder and tail wheel,
then securely tighten the set screw in the wheel collar
with a small drop of thread locking compound.
❏
4. If you’ve installed retracts, route the air lines
through the wing. Connect the lines in the fuse to the
control valve and the air tank in the fuse . Leave the
lines long enough so they can be connected to the
landing gear outside of the wing. Connect the air
lines to the landing gear, then mount the gear. If you
haven’t already done so, secure the set screw that
holds the axle to the strut and that holds the wheel
collars to the axles with a drop of thread locking
compound. Add a drop of oil to the axles.
❏
5. Mount the engine and muffler and hook up all
the systems inside the cowl including the fuel lines,
in-line fuel filler valve, etc.
❏
6. The same as instructed for the servo
extensions inside the wing, secure connections
between the battery lead and the switch. Make
certain none of the servo cords will interfere with the
landing gear or other systems.
❏
7. Mount the control horns to the control surfaces
(remember that the flap horns are mounted
“backwards”). Connect the servos to the receiver.
Turn on the radio, center the trims on the transmitter,
then center the arms on all the servos except the flap
servos. The arms on the flap servos should hold the
flaps up when the flap switch (or dial or slider) on the
transmitter is in the “up” position.
Do not use CA accelerator on any of the hinges
and do not glue the hinges with anything but thin
CA. Do not attempt to glue one half of the hinge
at a time. The hinges will not be properly secured
and could come out while the model is in flight.
