Follow these guidelines to properly mount the servos, receiver and battery.
0DNH FHUWDLQ WKH 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.

to extend the length of the servo lead. Additional Futaba extension cords of varying lengths are available
from your hobby dealer. Always use an extension of the proper length. Avoid plugging multiple extensions
together to attain your desired length. If distance is greater than 18” or multiple or high current draw servos
are being used, use Futaba Heavy-Duty servo extensions.

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.

The numbers indicate how many degrees each arm is “off” from 90 degrees to correct for

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.
8VH WKH 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.
