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.
