5. Cut three arms from the four-armed servo arms included
with the elevator and rudder servos. Enlarge the outer hole
of each servo arm with a 5/64" [2mm] drill bit. Install a screw-
lock pushrod connector into the outer hole of each servo
arm. Tighten them to the servo arms with a 2mm fl at washer,
knurled nut, and threadlocking compound. The nut should be
snug against the washer but still allow the pushrod connector
to rotate freely in the servo arm hole. Slide the pushrod wires
through the screw-lock pushrod connectors and attach the
servo arms to the servos (perpendicular to the servo case
pointing out) using the servo arm screws included with the
servos. With the elevators and rudder centered, thread a
3mm set screw with threadlocking compound into the tops
of the pushrod connectors and tighten it against the pushrod
wires. Cut away the excess pushrod wires 1/4" [6mm] beyond
the pushrod connectors.

1. Remove the stopper from the fuel tank and shake out
the contents.

2. The fuel tank can be assembled as a two line system
consisting of a vent (pressure) line to the muffl er and a
carb line. Filling and emptying of the tank would need to be
done through the carb line, or an optional fuel fi ll valve (not
included). The tank can also be assembled as a three line
system having a vent line, carb line, and fi ll line. If installing
a fi ll line, puncture the third hole in the top of the stopper
above the sealed off fuel tube hole. The fi ll and carb lines
should extend out 1/2" [13mm] beyond the stopper and the
vent line should be bent upwards and left uncut. With the
tubes installed in the stopper, fi t the stopper plates loosely
in place with the 3mm x 25mm Phillips screw to hold the
assembly together.

3. Fit the stopper assembly into the tank with the vent line
pointing toward the top of the tank, but not touching. The fuel
tubing and clunk (fuel pickup) on the carb line should almost
