Radio Installation - FUTABA 6EX-2.4GHZ Instruction Manual

6-channel, fasst radio control system for airplanes/helicopters

Follow these guidelines to properly mount the servos, receiver and battery.

• Make certain the 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. 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/helicopter 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.

• After the servos are installed, operate each servo over its full travel and check that the pushrods and servo arms do not

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 if there is no servo damage, excess battery drain will result.

• Use the mounting 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 you install the switch harness to the helicopter, please use the switch cover. Generally sandwich the frame by switch

and switch cover and securely tighten the screws. Different models might require different installations. In that case, please

follow the model instruction manual.

• To prevent the servo lead wires from being broken by vibration during ﬂight,

provide a margin so that the wire sticks out slightly and fasten it at suitable

points. In addition, periodically check the wire during daily maintenance.
