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.
