System Check And Operation - Tactic TTX403 Instruction Manual

SYSTEM CHECK AND OPERATION

WARNING! During all pre-fl ight preparations with the aircraft on the
ground, make sure the throttle stick remains at the minimum position
and 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 from the low position which would create a safety hazard. Make
sure all devices are properly mounted inside the model, and all wiring connections
are secure to prevent them from easily becoming dislodged during fl ight. For safety
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 fl ight.
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 reversing for that particular channel.
5. With both sticks at center position, move the trims 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 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 motor R.P.M. in the model.
7. Perform a "range check". The "range" is the safe operating distance
from the Tx to the Rx, and should be 150 meters. With the assistance of
another person, place the aircraft on the ground and walk 100 feet (30m)
away from the model. With the Tx pointed directly at the model, operate
the transmitter's controls, and ensure the movement of all surfaces are
according to the movement of the transmitter.
8. Anytime power is to be removed from the radio system, it's important to shut
down power in the aircraft fi rst. Otherwise, the aircraft could become out
of control and cause a safety hazard! Move the throttle stick to minimum
position to 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.
