Setup & Installation
Connecting the ESC and Motor
The HOBBYWING Quicrun 10BL120 G2 ESC and 3660SL G2 Motor are designed for easy connection. The ESC features 4mm bullet plugs for motor connections and an XT60 connector for the battery. Ensure correct polarity when connecting the battery.
The motor wires are typically marked A, B, C. Connect them to the corresponding A, B, C terminals on the ESC. If the motor spins in the wrong direction after calibration, you can swap any two of the motor wires to reverse the direction.

ESC Calibration with Radio
Before operating or programming, the ESC must be calibrated to your radio transmitter. This ensures the ESC correctly recognizes neutral, full throttle, and full reverse positions.
- Connect the ESC's throttle lead to Channel 2 on your receiver. Ensure the black wire of the ESC harness is connected to the thin edge (ground) of the receiver port.
- Hold down the SET button on the ESC's power switch.
- While holding the SET button, turn on the ESC. The ESC will start to beep and blink.
- When the ESC beeps once (red light blinks once), release the SET button. This indicates neutral position.
- Push the throttle trigger to the full forward position and hold it. Tap the SET button again. The ESC will beep twice (green light blinks twice). This sets the full throttle position.
- Push the throttle trigger to the full reverse position and hold it. Tap the SET button again. The ESC will beep three times (green light blinks three times). This sets the full reverse position.
- The ESC will then beep once, twice, and three times in sequence, confirming successful calibration.

Programming the ESC with the LED Program Card
The HOBBYWING Quicrun 10BL120 G2 ESC requires the LED Program Card for tuning. It is not compatible with LCD Program Boxes or OTA Programmers.
- Connect the LED Program Card to the dedicated programming port on the front of the ESC. Ensure the plug is oriented correctly (marked with positive, negative, and signal symbols).
- Connect a battery to the ESC.
- Turn on the ESC. The LED Program Card will power on and display the current settings.
- Use the "ITEM" button to cycle through the programmable items (e.g., Running Mode, Cutoff Voltage, Punch, etc.).
- Use the "VALUE" button to change the option for the selected item.
- Press the "OK" button to save the changes. The ESC will confirm with a beep.
- Once programming is complete, turn off the ESC and disconnect the Program Card.

Operating Tips
- Running Mode: Choose between "Forward with brake" (for racing), "Forward/Reverse with Brake" (training mode, requires neutral before reverse), or "Forward with reverse" (instant reverse, generally for special vehicles).
- Cutoff Voltage: Set the low voltage cutoff for your battery type (LiPo cells or Disabled for NiMH). Default settings are usually safe.
- Punch: Adjusts the linearity of the throttle. A higher level (e.g., Level 9) provides a more direct 1:1 throttle response, while lower levels introduce a slight delay, which can be useful for smoother acceleration or managing power.
- Drag Brake Force: Controls the automatic braking applied when the throttle returns to neutral. Useful for high-traction conditions or preventing the vehicle from rolling.
- Max. Brake Force: Sets the maximum braking power. Adjust this to prevent tires from locking up and spinning out, especially in varying traction conditions.
- Max. Reverse Force: Adjusts the maximum speed/power in reverse. Lowering this can help with smoother operation, especially if full reverse power is too aggressive.
- Neutral Range: Defines the dead band around the neutral throttle position. Increase this if your radio's neutral signal is inconsistent.
- Timing: Electronic timing advance for the motor. Increasing timing can make the motor faster but also increases temperature. Use with caution and monitor motor temperature.
- Lipo Cells: Set this to match your LiPo battery configuration (2S, 3S, 4S) or "Auto" for automatic detection.
- BEC Voltage: Adjusts the power supplied to the receiver and servos (6.0V or 7.4V). Choose 7.4V if using high-voltage servos.
Maintenance
- Regularly inspect all wires and connectors for damage or loose connections.
- Keep the ESC and motor clean from dirt, dust, and moisture. Although waterproof, proper cleaning extends lifespan.
- Ensure the cooling fan on the ESC is free from obstructions. The fan operates based on temperature, so it may not run constantly.
- Store the combo in a dry, cool place when not in use.
Troubleshooting
- Motor not starting or erratic behavior: Check all connections, ensure the battery is charged, and verify the ESC is properly calibrated to the radio.
- Incorrect motor direction: If the motor spins in the wrong direction after calibration, swap any two of the three motor wires connected to the ESC.
- ESC overheating: Reduce the timing setting, check gearing for excessive load, or ensure adequate airflow to the ESC.
- Calibration issues: If the ESC does not calibrate correctly (e.g., gets stuck at a step), ensure your radio's throttle trim is at neutral and re-attempt the calibration process.
