10. Install the throttle servo into the tray in the fuselage.
Drill a 1/16" [1.6mm] hole through each of the mounting
holes in the servo. Install and then remove a servo mounting
screw into each of the holes you have drilled. Apply a
couple of drops of thin CA into the holes to harden the
threads. After the glue has cured, install your servo.
❏
11. Install a brass-screw lock connector and nylon retainer to
the servo arm. Slide it onto the pushrod wire, center the servo
and install the servo arm onto the servo. Then install the servo
screw into the servo and a 6-32 x 1/4" [6mm] socket head cap
screw into the screw-lock connector.
❏
12. Cut the forward plywood pushrod support to fit
between the pushrod and the fuselage. Glue the two balsa
blocks to both sides of the support. Lightly sand the
fuselage where the support will be glued and then wipe the
area with rubbing alcohol. Glue the forward support to the
fuselage side and glue the rear support to the servo tray.
❏
13. Assemble the fuel tank as shown. Included with the
fuel tank hardware is a 24" length of fuel tubing. This will be
used for attaching the tank to the carburetor and muffler
pressure tap. If you will be using a fuel valve (not included)
for filling the tank rather than filling the tank by removing the
line from the carburetor, install it in the fuel line following the
instructions included with the valve.
❏
14. Install the fuel line included with the kit onto the tubes
extending from the fuel tank. Insert the lines and the fuel
tank into the fuselage. Hold the tank in place with a couple
of #64 rubber bands. Attach the carburetor line to the
carburetor. The vent line can be attached later when the
muffler is permanently installed.

1. Use card stock as a template for making the cut out in
the cowl. Tape the card stock to the fuselage behind where
the cowl will be mounted. Mark the card stock where the
engine extends outside of the cowl. Cut that area out of the
card stock.
❏
2. Remove the engine from the mount; slide the cowl onto the
fuselage. (If you are installing the O.S. .91 four stroke engine,
you can remove the rocker arm cover and the cowl will fit over
the engine without removing it.) Tape the cowl to the fuselage.
Trace the pattern from the card stock onto the cowling.
❏
3. Remove the cowl from the fuselage. Cut out the area
you have marked. A high speed rotary tool works well for
this. Try to cut as closely to the area outlined as you can.You
will be making adjustments to the cut out as you continue
with the installation of the cowl. The goal now is to just be
able to slip the cowl over the engine and onto the fuselage.
❏
4. Reinstall the engine onto the engine mount. Slide the
cowl over the engine and onto the fuselage.
Install the Cowl
