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.
FAILSAFE NOT WORKING CORRECTLY
Receiver is not properly binded to the transmitter – bind
the Rx to the Tx and re-try. Contact Hobby Services for
further details.
WIRELESS TRAINING FUNCTION NOT BINDING
Check to see that another Tactic 2.4GHz system is not on
in your area. The teacher’s and student’s transmitters were
not powered in the proper sequence. Carefully follow the
instructions on page 17 for proper binding and operation
for training.
RECHARGEABLE BATTERIES WON’T ACCEPT CHARGE
THROUGH THE TRANSMITTER
Check the charger for proper setup and operation. Make
sure the charge plug is inserted fully into the charge jack.
Make sure the transmitter’s power switch is in the OFF
position. Make sure the cells are inserted inside the battery
compartment in the proper direction.
