RADIO INSTALLATION RADIO INSTALLATION
Follow these guidelines to properly mount the servos, receiver and battery.
•• Make certain the alignment tab alignment tab on the battery, switch and servo connectors is oriented correctly and “ keys ” into the
corresponding notch in the receiver or connectors before plugging them in. When unplugging connectors, never pull on the
wires. Always pull on the plastic connector instead.
•• If any servo wires are not long enough to reach the receiver, servo extension wires (available separately) may be used.
•• Always mount the servos with the supplied rubber grommets rubber grommets. Do not over tighten the
screws. No part of the servo casing should contact the mounting rails, servo tray or any
other part of the airplane structure. Otherwise, vibration will be transmitted to the servo
causing premature wear and/or servo failure.
•• Note the small numbers (1, 2, 3, 4) molded into each arm on the Futaba 4-arm servo arms.
The numbers 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 the receiver and turn on
the transmitter and receiver. Center the trims on the
transmitter, then find the arm that will be perpendicular to the
pushrod when placed on the servo.
