Receiver Installation for Electric Motor
5. Use a hobby knife and #11 blade to remove the plywood
between the two slots in the radio tray to pass the servo
leads through to the receiver.
6. Temporarily install the battery tray to help locate the
receiver when it is installed in the fuselage.
 The nylon bolt can be shortened using a
razor saw to make its installation easier.
7. Secure the receiver in the fuselage using two-sided
tape and a hook and loop strap. Connect the rudder and
elevator servos to the receiver.
 When using the recommended receiver,
make sure it is secure and installed according to
the instructions provided with the receiver.
All Motor and Engine Options
8. Secure the remote receivers in the fuselage using hook
and loop tape. Locate the fi rst receiver at the rear edge
of the servo tray.
9. The second receiver is located inside the fuselage as far
forward as it can be placed. Secure it using hook and
loop tape.

10. Center the stick and trim at the transmitter and check
the operation of the servos. Instal the servo arms on the
servos perpendicular to the servo centerline. The rudder
servo will use a double-sided servo arm.
 When using the longer 3-inch (76mm) servo arm,
it will be necessary to shorten the arm, or rotate the
servo so the output faces to the back of the fuselage, to
allow clearance between the arm and elevator servos.
 When using Dubro servo arms for the elevator servos,
it may be necessary to them near the servo output to allow
clearance for the longer 3-inch (76mm) rudder servo arm.
11. Connect 12-inch (300mm) extensions for the fl aps and
ailerons. Route the extensions through the openings in
the fuselage.
 RUDDER AND FIN INSTALLATION
1. Slightly remove the rudder hinge pin so the lower hinge
in the fuselage can fi t into the rudder.
2. Check the fi t of the rudder to the fuselage. The base
of the fi n will fi t snugly against the fuselage as shown.
Remove the fi n and rudder from the fuselage.
3. Mix 3/4 ounces (25cc) of 30-minute epoxy. Use an epoxy
brush to apply the epoxy to the exposed wood where the
base of the fi n fi ts against the fuselage.
