wheel collar SHCS (6-32 x 1/4" [6.4mm]). Note: The
preceding image shows the completed pushrod assembly
outside of the radio compartment for clarity.

8. Install a screw-lock pushrod connector on the throttle

servo arm. Insert the throttle pushrod into the connector.
Use a 4-40 x 1/8" [3.2mm] socket head cap screw to secure
the pushrod into the connector. Make sure that you get the
full range of carburetor rotation with the servo rotation. Use
some Great Planes Pro Thread Locking Compound on the
SHCS to prevent it from coming loose with vibration.

9. Install a radio switch and a charge receptacle on the

fuselage’s side away from the exhaust. Wrap the battery
pack and the receiver in at least 1/4" [6.4mm] of R/C foam
rubber and install them in the fuselage. Use shrink tubing to
secure the battery and switch connections. Connect all your
servos and the “Y” harness to the receiver. Glue two 1/2" x
1/4" [12mm x 6.4mm] balsa sticks (not included) to secure
the battery and receiver in place.

10. Make a small hole through the bottom of the fuselage

and route the radio antenna to the aft fuselage. Be sure that
there is a strain relief inside the fuselage on the antenna to
keep stress off the solder joint inside the receiver. Use a
small rubber band to keep the antenna extended. Hold it
with a T-pin at the bottom of the fuselage or around the tail
wheel wire.

1. Draw a line 1/2" [12mm] away from the firewall, parallel

to the firewall.

2. Test fit the cowl on the fuselage. Push the cowl all the

way up to the line. Center the cowl ring with the engine
crankshaft. Use a rotary tool to cut cooling openings and a
carburetor opening on the fiberglass cowl. Hint: It will be
easier to line up the cowl with the engine crankshaft if you
temporarily install the spinner back plate. There should be a
3/32" [2.4mm] gap between the spinner back plate and the
cowl ring.
