MOUNTING THE COWL

1. Remove the muffler and needle valve 

assembly from the engine. Slide the fiberglass 
cowl over the engine.

2.  Measure and mark the locations to be cut out 

for engine head clearance, needle valve, 
muffler,. Remove the cowl and make these 
cutouts using a rotary tool with a cutting disc 
and a rotary sanding drum attachment.

INSTALLING THE THROTTLE

1.  Install one adjustable metal connector through 

the third hole out from the center of one servo 
arm, enlarge the hole in the servo arm using a 
2mm drill bit to accommodate the servo 
connector. Remove the excess material from 
the arm.

    After installing the adjustable metal connector 

apply a small drop of thin C/A to the bottom 
nut. This will prevent the connector from 
loosening during flight.

2.  Plug the throttle servo into the receiver and turn 

on the radio system. Check to ensure that the 
throttle servo output shaft is moving in the 
correct direction. When the throttle stick is 
moved forward from idle to full throttle, the 
throttle barrel should also open and close using 
this motion. If not, reverse the direction of the 
servo, using the transmitter.

3.  Slide the adjustable metal connector / servo 

arm assembly over the plain end of the 
pushrod wire. Position the throttle stick and the 
throttle trim at their lowest positions.

4. Manually push the carburator barrel fully closed. 

Angle the arm back about 45 degree from 
center and attach the servo arm onto the servo. 
With the carburator barrel fully closed, tighte 
the set screw in the adjustable metal connector.

5.  Remove the excess throttle pushrod wire using 

wire cutters and install the servo arm retaining 
screw.
