5. Setup

Before initial use, ensure all components are properly connected. The ESC and motor are designed for seamless integration. The ESC comes pre-installed with 12-gauge wire and an XT60 connector. The motor features 4mm bullet connectors for easy connection to the ESC.

5.1 Connecting the ESC and Motor

Connect the three motor wires to the corresponding 4mm bullet plugs on the ESC. The motor wires are typically marked A, B, C and should be connected to the 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.

5.2 ESC to Receiver Connection

Plug the ESC's input harness into Channel 2 of your receiver. Ensure the black wire aligns with the negative pin on the receiver. Incorrect polarity can damage the receiver.

5.3 Initial Calibration

It is crucial to calibrate the ESC to your radio transmitter before first use. This process teaches the ESC the neutral, full throttle, and full reverse positions of your transmitter. Refer to the detailed video below for a step-by-step guide on calibration.

6. Operating Instructions

Once the ESC is calibrated, you can begin operating your vehicle. The ESC features various programmable items that allow you to fine-tune its performance according to your preferences and driving conditions. These settings include running mode, cutoff voltage, punch, drag brake force, max brake force, max reverse force, neutral range, timing, LiPo cells, and BEC voltage.

6.1 Running Mode

The running mode can be set to "Forward with brake" (for racing), "Forward/Reverse with brake" (training mode, vehicle brakes then reverses), or "Forward with reverse" (instant reverse, common in special vehicles).

6.2 Cutoff Voltage

This setting protects your battery from over-discharge. It can be disabled for NiMH batteries or set to specific voltage per cell for LiPo batteries (e.g., 3.0V/Cell, 3.2V/Cell, 3.4V/Cell). Adjusting this can impact runtime and battery health.

6.3 Punch

The punch setting controls the linearity of the throttle response. A lower punch setting provides a more gradual throttle, while a higher setting (up to Level 9) offers a more direct and aggressive response, ideal for experienced users with good battery packs.

6.4 Drag Brake Force

This applies a continuous braking force when the throttle is at neutral. Useful for high-traction conditions or preventing the vehicle from rolling on inclines. Options range from 0% (disabled) to 100%.

6.5 Max Brake Force

Adjusts the maximum braking power. If the full brake causes tires to lock up or the vehicle to spin out, reducing this value can provide more controlled braking. Options range from 25% to 100% (disabled).

6.6 Max Reverse Force

Controls the maximum speed in reverse. Options range from 25% to 100%.

6.7 Neutral Range

Defines the dead band around the neutral throttle position. Increasing this value can help if your transmitter's throttle trigger is inconsistent or "bouncy" around neutral.

6.8 Timing

Electronic timing advance to the motor. Increasing timing can make the motor faster across its RPM range, but it also increases motor temperature. Use with caution and monitor motor temperatures. Options range from 0° to 26.25°.

6.9 LiPo Cells

Allows the ESC to automatically detect the number of LiPo cells ("Auto") or manually set it to 2S, 3S, or 4S. For 4S operation, only larger scale motors (4268 size) are recommended due to higher voltage demands.

6.10 BEC Voltage

Sets the output voltage of the built-in BEC to power the receiver and servos. Options are 6.0V or 7.4V. Choose 7.4V if you are using high-voltage (HV) servos.

7. Tuning and Programming

The Quicrun 10BL120 G2 ESC requires the HOBBYWING LED Program Card for tuning and programming. This ESC is not compatible with LCD Program Boxes or OTA Programmers. The program card connects to a dedicated port on the front of the ESC, clearly marked for correct orientation.

7.1 Using the LED Program Card

1. Connect the LED Program Card to the dedicated port on the ESC.
2. Connect a battery to the ESC.
3. Turn on the ESC. The LED Program Card will power on and display the current settings.
4. Use the "ITEM" button to cycle through the programmable items (1-10).
5. Use the "VALUE" button to change the option for the selected item.
6. Press "OK" to save the changes. The ESC will confirm with a series of beeps.
7. To reset to factory defaults, press the "RESET" button, then "OK".

Important: Always refer to the specific setting chart provided in your physical manual or the official HOBBYWING website for the exact values and options for each programmable item, as the sticker on the program card itself may not always match the latest firmware settings.

8. Maintenance

• Regularly inspect all wires and connectors for damage or loose connections.
• Keep the ESC and motor clean from dirt, dust, and moisture. Despite IP-67 rating, prolonged exposure to water or mud should be followed by thorough cleaning and drying.
• Ensure the cooling fan on the ESC is free from obstructions.
• Store the product in a dry, cool environment when not in use.

9. Troubleshooting

If you encounter issues with your Quicrun combo, refer to the following common problems and solutions:

9.1 ESC does not turn on after power-up:

• Check battery connection and ensure the battery is charged.
• Verify the power switch is correctly connected and not damaged.

9.2 Motor does not start after power-up:

• Ensure the ESC is properly calibrated to your radio transmitter.
• Check motor wire connections (A, B, C) for proper contact.
• Verify the receiver is powered on and correctly bound to the transmitter.

9.3 Inconsistent or no reverse:

• Ensure the running mode is set to "Forward/Reverse with brake" or "Forward with reverse".
• Recalibrate the ESC to the radio, paying close attention to setting the neutral point and full reverse.
• Adjust the "Neutral Range" setting if the neutral point is unstable.

9.4 Overheating:

• Check motor gearing; ensure it's appropriate for your vehicle and driving conditions.
• Ensure the cooling fan on the ESC is functioning and not obstructed.
• Reduce the "Timing" setting if the motor is running excessively hot.
