Refer to this photo for the following two steps.

17. Mount the aileron servo in the wing. The same as you

should be doing all along, don’t forget to harden the screw
holes with thin CA. Make a two-arm servo arm by cutting off
the unused arms.

18. Thread a torque rod horn onto each torque rod until

the top of the horn is even with the top of the torque rod.
Make the aileron pushrods and connect them to the aileron
servo and the torque rod horns the same way you did the
elevators and rudder.

19. Mount the main landing gear in the wing using the

screws and straps.

1. Make the receiver tray and battery tray by gluing the

balsa and plywood parts together as shown. When over-
turned you will be able to slip tape or Velcro

®

around the

trays to hold the battery pack and receiver down.

2. Wrap the receiver and battery in 1/4" [6mm] R/C foam

rubber. Hold the foam in place with small rubber bands or
tape. Mount the receiver and battery to the trays with tape
or Velcro.

3. Mount the on/off receiver/battery switch to the side of

the fuselage opposite the engine exhaust. There are cut outs
in the fuselage sides that should accommodate most types of
switches. The model shown in the manual uses the Great
Planes Switch & Charge Jack Mounting Set (GPMM1000).
This serves both as a switch mount and a charge jack mount
for a battery charger or volt meter. The setup must be
mounted upright, so the switch slide block must be tack-glued
to the switch with a small drop of medium CA so it doesn’t fall
off when overturned for mounting.

4. Securely glue the receiver and battery trays in the

fuselage where they will fit. Make sure they do not interfere
with the servos or on/off switch. It’s best to mount the battery
pack in front of the receiver.

5. Make a strain relief for the receiver antenna from a

leftover servo arm. Guide the antenna through the holes in
the arm.
