10)  OPTIONAL SPINNER: A 2” dia. spinner is included in this kit.
No doubt it will be used by almost everyone who is installing a glow
engine. However with an electric motor you may prefer to not use
the spinner in order to allow more cooling air to flow into the 
cowling. If you do elect to use a spinner, check after the first 
couple flights for any sign of the motor overheating. If you think it’s
getting too hot, you may need to make some additional openings
in the front of the cowling for additional cooling air to enter. Also
make sure you have plenty of exit area for the air. In any fully
cowled installation (glow or electric), it is critical that you have
slightly more exit area than incoming area. Having more exit area
creates a positive air flow through the cowling - a suction affect -
drawing the heated air out of the cowling so that more cool air can
come in.

NOTE: The receiver and servos of different brand radios are not all
the same size!  Consequently, it is practically impossible for us to
guarantee that every word and picture in this next sequence will
pertain exactly to your installation. As you go along, you may notice
some differences between your radio equipment and ours.
Nonetheless, most of the radio system components will be close
enough in size and appearance that you should be able to figure
out for yourself how to handle any minor differences. Follow the
instructions as closely as possible. If you have any questions, seek
the advice of an experienced modeler.

The installation of the 

control system in your new model is very important!  It must be
done correctly in order for your airplane to fly successfully.

INSTALL THE  SWITCH
The first step is to mount the radio's on/off switch in the left side of
the fuselage (the side away from the exhaust). Start by using the
switch cover plate as a template to mark the location and size of
the opening and the two holes for the mounting screws. Use a
modeling knife to cut the opening. Use a 1/16" dia. drill to make
the holes for the screws. Install the switch.

CAUTION: Make sure the opening for the switch's on/off lever is
just slightly bigger than the lever, so that the switch will operate
without catching or binding on the wood.

INSTALL THE ELEVATOR & RUDDER SERVOS
Mount your elevator and rudder servos in the plywood Servo Tray
using the screws and rubber grommets that came with your radio
system. Be sure to orient the servos in the tray as shown here.

CAUTION: The rubber grommets that came with your servos act
as shock absorbers and prevent engine vibration from damaging
the electronics in the servos.

Do not over tighten the servo 

mounting screws to the point where they compress the rubber

grommets so far that the grommets loose all shock absorbing 
ability. Tighten the screws just enough to make contact with the
grommets and keep the servos in place.

NOSE GEAR PUSHROD
Locate the following parts from the kit contents:

❑

(1) Nylon Outer Pushrod Sleeve (already in the fuselage)

❑

(1) 1/16” dia. x 16” straight Music Wire Pushrod

❑

(1) Brass Pushrod Connector

❑

(1) Plastic Pushrod Connector Retainer

❑

(1) 4-40 x 1/8” Pushrod Connector Bolt

1) Install a complete Pushrod Connector assembly in the 
outermost hole of the nose gear Steering Arm. Install the Pushrod
Connector on the BOTTOM of the Steering Arm. NOTE: It will
probably be necessary to open up the hole in the steering arm with
a 1/16” drill bit to allow the connector to go in freely.

2) The plastic outer sleeve for the nose gear pushrod is already
installed in the fuselage, but not glued. Position the sleeve so that
the front end is flush with the front of the firewall. Then glue the
plastic pushrod tubing permanently in the hole in the left side of the
fuselage former, in front of the servos.

3) A piece of straight 1/16” dia. Music Wire is provided to make the
nose gear pushrod. Use a diagonal cutting pliers to cut the piece
to 14" long. Remove any burrs from the ends of the wire with a file.

4) Make a "Z-BEND" in one end of the 14” wire. This will be the
end of the pushrod that attaches to the rudder servo.

See 

“MAKING A Z-BEND IN 5 EASY STEPS” on page 23.

5) Insert the Z-BEND into the middle hole of the rudder servo arm.
The Z-BEND should go into the servo arm from the BOTTOM, as
shown in the next photo.
