2. Over-heat protection: When the temperature of the ESC is over 95℃ for 5 seconds, the ESC will cut off the
output power. You can disable over-heat protection function for competition race.
3. Throttle signal loss protection: The ESC will cut off the output power if the throttle signal is lost for 0.2 second.
Trouble Shooting
Always start troubleshooting by resetting the ESC to the throttle range of the transmitter. Calibration will
most likely solve the issue. (Throttle range calibration above)
Optional Accessories for Upgrade
We provide the following optional accessories for upgrade your power system:
1. Heat sink fan (8V): The fan is necessary when you are using battery pack more
than 6 cell NiMh/NiCd or 2s Lipo. It is located on the heat sink of the ESC, it helps to
cool the ESC with downward airflow. The picture on the right side shows the installation.
WARNING! Please note the fan sold with the ESC can ONLY work with a 2 cell
lithium battery pack or 4-6 cell NiMh / NiCd battery pack. Please NEVER use it
with a 3-4 cell lithium battery pack or NiMh / NiCd battery pack more than 7 cells,
otherwise it may be destroyed.
Please check the label of the fan to confirm its working voltage before using it.
2. High capacity filtering capacitors with extreme lowest resistance.
3. Multi ESC Program Card.
Program the ESC
Program card is an optional accessory which may be purchased separately.
Programming the ESC is very easy and fast with this pocket sized device. To
change settings, just plug the receiver wire from the ESC (trio wires with black, red and white color) into the socket of
the program card (The socket is on the right corner, and marked with ), and then power up the ESC, each
item’s value will be shown on the program card. Use “ITEM” and “VALUE” buttons to select the programmable items
and new values, and press the “OK” button to send the new settings into the ESC.
