IMPORTANT WARNINGS
AND PRECAUTIONS
●
NEVER
allow water or moisture to make
contact with the electronic components inside the
transmitter, receiver, servos, switch harness, etc.!
This could lead to failure or improper functionality
of components and poor control of aircraft which could
pose a safety hazard.
●
NEVER
operate R/C model aircraft near power lines, radio
or cell phone towers, roads or automobiles, buildings, or
pedestrians. Be very careful in locations where many R/C
aircraft are being used simultaneously.
●
NEVER
operate R/C equipment if you are physically
impaired as it could pose a safety hazard to yourself or
others in the area.
●
NEVER
allow small children to operate/control model R/C
equipment without the supervision of an adult.
●
NEVER
allow the transmitter’s throttle stick to accidentally
be moved away from the “off” or minimum position while
the model’s engine/motor is moving.
●
ALWAYS
range check the radio system before use.
●
ALWAYS
make sure that all transmitter stick movements
operate all servos properly in the model. Check the proper
operation of control surfaces before and after starting the
engine/motor.
●
ALWAYS
make sure the transmitter antenna is unfolded
entirely so that it’s pointing upright to ensure max. range
and control of the aircraft.
●
Do not store your radio equipment in extremely hot or
cold locations, in direct sunlight, or in locations with high
humidity. Store R/C equipment in cool and dry locations.
●
Do not allow chemicals to come in contact with any parts of
the radio system. Substances such as glow fuel, gasoline,
CA glue, etc. could permanently damage plastic parts of
the radio system.
●
If NiCd batteries were installed in the transmitter, remove
the batteries before placing the radio in long-term storage.
TROUBLESHOOTING
RANGE IS SHORT
Interference – check Rx installation and servo connections.
Low Tx or Rx battery – replace the batteries or recharge if
applicable. Rx may need to be located to a different position
in the model for better reception. Crash damage – send the
radio to Hobby Services for repair.
RUN TIME IS SHORT
Low Tx or Rx batteries – replace or recharge the batteries.
Obstructed servo linkages causing excess battery drain –
free the linkages / pushrods.
Tx POWER SWITCH ON BUT SERVOS DO NOT FUNCTION
Tx or Rx batteries are low – replace or recharge the batteries.
Rx switch is in the off position – turn on the ESC or switch
harness. Switch harness or ESC is connected incorrectly –
check all connections and the ESC instruction manual. Rx
is not binded to the Tx properly – perform binding process
again. Check Tx or Rx battery polarity.
INTERFERENCE OR SERVOS GLITCHING
Out of range – operate the model more closely to the transmitter.
Outside radio interference from pagers, strong industrial or
other commercial transmitters in the area - check your local
R/C club regarding local operation. Rx located too closely to
engine, motor, or servos or other moving mechanical parts
which might be creating unwanted electrical noise – relocate
the Rx inside the model or relocate the ESC.
CONTROL SURFACE MOVES IN THE WRONG DIRECTION
Reverse the position of the reversing switch for the
appropriate channel.
ONLY ONE SERVO GLITCHES
Servo is bad – replace the servo or send to Hobby Services
for repair.
