Battery voltage automatic cutoff setting

ESC Overheat protector

When the motor temperature reaches 98 ℃ ( ± 3-5 ℃ ) ESC will intermittently repeats on and off .

ESC wiring diagram

The receiver connector connects to CH2. The polarity matches Sanwa, KO and Futaba receivers. Check the polarity for other brands of receivers before plugging in.

Throttle Neutral setting

Caution

1. After driving, ESC is hot around heatsink and motor case, so don’t touch it.
2. Always use connectors and wires with good current ratings. Replace the original ESC connector, or extend the connecting wire to make adjustments to avoid poor connector contact, melting due to overheating, and abnormal power cutoff .
3. Connect the battery just before driving and disconnect it after driving. Also, do not solder the battery directly to ESC, use the appropriate connector in between.
4. Always connect a power source with the correct voltage and polarity to the ESC. Using power sources with different voltages or polarities can damage the ESC. Also, do not solder the ESC wire directly to the battery, be sure to use a connector in between.
