Otherwise vibration will be transmitted to the servo causing damage of servo. Note the small
numbers (1,2,3,4) molded into each arm on the servo arms. The number indicate how many degrees
each arm is ‘off’ from 90 degrees to correct for minute manufacturing deviations from servo to
servo.
To center the servos, connect them to receiver and turn on the transmitter and receiver. Center the
trims on the transmitter, then find the arm that will be perpendicular to the push rod when placed on
the servo.
After the servos are installed, operate each servo over its full travel and check that the push rods and
servo arms don ’ t bind or contact each other. Also make sure the controls do not require excess
force to operate. If there is an objectionable buzzing sound coming from a servo, there is probably
too much resistance in the control. Find and correct the problem. Even there is no servo damage,
excess battery drain will result.
•Use the mouthing plate from the receiver on/off switch as a template for the cutout and screw holes,
mount the switch on the side of the fuselage opposite the engine exhaust, and where it won’t be
inadvertently turned on or off during handling or storage. Be certain the switch moves without
restriction and ‘ snaps ’ from ON to OFF, and that the cutout allows full motion of the switch in
both directions.
•When install the switch harness to the helicopter, please use the switch cover. Generally sandwich
the frame between the switch and switch cover and securely tighten the screws. Different models
might require different installations. If so, please follow the model’s instruction manual.
• To prevent the servo lead wires from being broken by vibration during flight, provide a slight
amount of slack or extra so that the wire sticks out slightly and fasten it at suitable points. In addition,
periodically check the wire during daily maintenance.
