SERVOS
Center all trims on the Tx. Install the servos in the
model and connect linkages as shown in the model’s
instructions. Do NOT over-tighten the mounting screws,
as the servos should be able to move slightly to
compensate for engine vibration. Make sure the
pushrods are not too loose or bind in any way, and
use a servo arm which allows for full range of motion for the servo. This can be tested by moving the Tx
sticks to maximum positions several times while observing the movement of the control surfaces. Adjust
binding servos/linkages to prevent excessive draining of the battery. Move the Tx trims to fi nely adjust the
servo’s center point as needed for the application.

To Charger
Connect the servos to the Rx as shown. Route the wires to not interfere with moving parts. See the SERVOS
AND ACCESSORIES section on page 12 for a full list of optional servos.
ELECTRIC MODELS
An optional ESC (electronic speed control) will be necessary to control speed of the electric motor, and to
supply power to the receiver and servos. Connect the ESC’s receiver plug to Rx slot marked CH3 (for throttle).
Center the transmitter’s throttle trim and follow the ESC instructions for proper operation and connection
of the battery.
COMBUSTION MODELS
Individual “AA” NiCd or NiMH rechargeable batteries can be installed in the included battery holder to power
the fl ight electronics (do not use alkaline cells). An optional rechargeable battery pack could instead be used.
See the SERVOS AND ACCESSORIES section on page 12 for suggested options. The included switch
harness can conveniently turn power ON/OFF to the fl ight electronics. Refer to the model’s instructions for
the optimum location to mount the battery, Rx, and switch harness for optimum weight distribution.
IMPORTANT!
Apply power to the Tx BEFORE applying power to the Rx, and make sure
the Tx throttle stick is at minimum (idle) position. Failure to do so could result in the model
becoming uncontrollable and cause a safety hazard.
