transmitter's Rf section is turned ON, the Tx will automatically shut down 120 seconds after this message shows. If
the Rf section is turned OFF, the Tx will shut down 60 seconds after this message shows.
SYSTEM CHECK AND OPERATION
WARNING! Always make sure that power is applied to the transmitter BEFORE applying power
to the receiver and servos, and 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.
During all pre-
flight preparations, do not stand the Tx upright on the ground. Carefully lay the Tx on its back on the ground to
prevent it from falling over and possibly dislodging the throttle stick which would create a safety hazard. Make
sure all devices are properly mounted inside the model, and all wiring connections are solid to prevent them from
easily becoming dislodged during normal flight. It’s best to check the system with the propeller removed from the
aircraft.
1. Once all connections are made, check the general operation of the radio and all other components before
attempting a flight.
2. Move the Tx throttle stick to the minimum (idle) position.
3. Turn on the Tx, and then the Rx.
4. Make sure all controls are operating in the proper direction. If any servo is turning in the wrong direction,
change the reverse setting for that channel.
5. With both sticks at center position, move the trim levers for the aileron, elevator, and rudder channels so each
respective control surface is perfectly aligned with the main surface. For example: when the aileron trim lever is at
center, it’s best that the trailing edge of the aileron is aligned with the trailing edge of the wing itself (not above or
below the wing’s trailing edge).
6. Make sure that movements of the throttle stick result in an equal adjustment of the throttle in the model.
Depending on whether the model is electric or glow powered:
a. Electric: confirm that when the throttle stick is at maximum position the electronic speed control gives the
appropriate indications (LED and/or audible indicators) for full forward flight. And, when the throttle stick is at
minimum position the electronic speed control gives the appropriate indications for “off” or no motor rotation.
b. Glow: confirm that when the throttle stick is at maximum position the mechanical linkage to the engine
allows the engine to be at full throttle. And, when the throttle stick is at minimum position and the throttle
trim lever is moved to minimum position, the engine stops completely.
7. Perform a range check as explained on page xx.
8. Anytime power is to be removed from the radio system, it’s important to shut down power in the aircraft
first
.
Otherwise, the aircraft could become out of control and cause a safety hazard! Move the throttle stick and throttle
trim to minimum position to stop the glow engine or shut down the ESC. Once the propeller has stopped rotating,
shut off the ON/OFF power switch in the model, and disconnect the power battery from the ESC in electric
airplanes. Then turn off the power switch in the Tx.
