18. Troubleshooting
Even though the remote control system was built to the latest available technology, malfunctions or faults might still
occur. The following section shows you how to troubleshoot potential faults.
Problem
Solution
The transmitter does not
respond
•
Check the batteries in the transmitter and replace them with new ones, if
necessary.
•
Check that the batteries are inserted correctly.
•
If you are using a two-cell LiPo rechargeable battery (rated voltage 7.4 V)
with BEC connection for the transmitter, be sure to charge it.
The servos do not react.
•
Check the voltage/power supply of the receiver.
•
Test the BEC function of the speed controller.
•
Check the polarity of the servo plugs.
•
Re-pair the receiver with the transmitter (use the binding function).
•
Check the dual rate setting of the transmitter (if the dual rate setting is too
low, the servos will stop working).
•
Check the EPA setting of the transmitter.
The servos shake.
•
Check the voltage/power supply of the receiver.
One servo is humming.
•
Check the voltage/power supply of the receiver.
•
Check that the linkage rods run smoothly.
•
The servo is running against the stop, limit the servo travel using the EPA
setting.
•
For test purposes, operate the servo without the servo lever.
The system has only a low
range
•
Fold up the transmitter antenna.
•
Do not point the transmitter antenna to the model. Both antennas must be
parallel for optimal range.
•
Check the voltage/power supply of the receiver.
•
Check the batteries in the transmitter and replace them with new ones, if
necessary.
•
If you are using a two-cell LiPo rechargeable battery (rated voltage 7.4 V)
with BEC connection for the transmitter, be sure to charge it.
•
For test purposes, reorient the receiver antenna. To achieve a high range, the
antenna must protrude as vertically as possible from the vehicle.
The transmitter turns off straight
away or after a short while
•
Check the batteries in the transmitter and replace them with new ones, if
necessary.
