The following indications will sound and/or show if any of the following occur:
LOW BATTERY:
Battery voltage is at or below the BATT. ALARM setting. Cannot change memories
at this time. Replace or re-charge batteries.
RF ON / OFF?:
Turn the radio’s Rf signal on or off.
THRO POS.:
The throttle stick is >25% full defl ection at start-up. Move the throttle stick to minimum.
THRO CUT:
The throttle cut function has been set and the switch is on. Turn the switch off.
NO SIGNAL:
While in wireless training mode, if the signal between the teacher and student transmitters
becomes un-linked.
AUTO SHUTDOWN:
If no transmitter stick or control is moved after 10 minutes have elapsed, this
warning screen will show and the Tx will proceed to shut itself down to prevent unwanted drainage
of the batteries. If the 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.
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-fl ight 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 fl ight. 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 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: confi rm 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 fl ight. 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: confi rm 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.
