❏
4. Apply 6 drops of thin CA adhesive to both
sides of each hinge on the elevators and
rudder only – not the ailerons yet.
Allow a few
seconds between drops for the CA to wick into the
slot. Note that the small “tunnels” you created by
drilling the 3/32" holes allow the CA to freely travel
in to the entire surface of the hinge, producing an
extremely secure bond.
FINAL CONTROL
HARDWARE HOOKUPS
❏
1. Drill 1/16" holes to mount the control horns in
the 1/8" ply reinforcement blocks installed earlier.
Apply a drop of CA in each hole to harden the
area. Install the flap and aileron horns with the #2 x
3/8" sheet metal screws.
❏
2. Cut down a large round servo horn as shown on
the plan - use ball links (not included) or your favorite
method to hook up the ailerons. Hook up and adjust
aileron and flap linkages at the horns. Make sure they
are centered. Refer to the Control Surface Throws
section for movement recommendations.
❏
3. Great Planes Nylon Pushrod Connectors (not
included) are recommended for elevator and
rudder hookups. Simply bend a 90 degree angle in
the pushrod wire and install the connector.
❏
4. The throttle linkage is left up to you due to the
variety of engine types and orientations possible.
❏
5. The receiver switch can be mounted in the aft
portion of the forward frame in the fuselage as
shown in the photos.
6. The following procedure was followed to mount
the GPM 12 oz. fuel tank:
❏
A . Assemble the tank per tank instructions. Use
extra long external fuel lines for the rigging process.
❏
B . Make the plywood cross-member (visible in
the preceding photo) from leftover balsa and fit it
between the two
wing saddles .
❏
C . Glue approximately 1/2" x 1" x 3" pieces of
dense latex foam rubber to one side of the cross-
member and to the top of the front shelf of the
forward frame. Glue a 1/2" x 1" x 4" strip of latex
foam to the inside edge of F-3.
❏
D . Feed the fuel lines through the holes in the
firewall and gradually pull the tank into position.
(See the fuselage side view plan for tank position.)
❏
E . Push the cross-member down onto the tank
firmly. Make sure none of your lines are kinked.
Glue the cross-member to the wing saddles.
COCKPIT FINISHING
(Basic cockpit)
❏
1. Sand the inside of the cockpit around the
edges with 320-grit sandpaper. True up any
uneven edge in the cockpit area.
❏
2. Test fit the pilot into the model. Our Williams
Brothers scale pilot required a 3/8" block under him
to adjust his height. Assemble and paint your pilot.
