3. Safety Precautions
Always observe the following safety guidelines when handling and operating the ESC:
- Ensure all connections are secure and properly insulated to prevent short circuits.
- Verify the battery voltage and polarity before connecting to the ESC. Incorrect voltage or reverse polarity can cause severe damage.
- Keep hands and loose clothing away from rotating propellers or other moving parts when the motor is connected and powered.
- Operate in a well-ventilated area to prevent overheating.
- Disconnect the battery from the ESC immediately after use and before performing any maintenance or adjustments.
- Do not expose the ESC to water or moisture unless it is specifically designed for waterproof applications.
- Children should only operate this device under adult supervision.
4. Product Overview and Connections
The ApisQueen Thunder-80-01 ESC features standard connections for power input, motor output, and signal input. Familiarize yourself with the components as shown below.

Image 4.1: ApisQueen 80A ESC with labeled connections. The image highlights the XT60 connector for battery input, the BEC gear switch for selecting 5V, 6V, or 7V output, the PWM signal line (white wire), BEC output (red wire), ground wire (black wire), and the three 4.0mm plugs for motor connection.
- XT60 Connector: For connecting the LiPo battery (2-6S).
- BEC Gear Switch: Allows selection of BEC output voltage (5V, 6V, or 7V). Default is 5V.
- PWM Signal Line (White Wire): Connects to the receiver's throttle channel.
- BEC Output (Red Wire): Provides regulated power to the receiver and servos.
- Ground Wire (Black Wire): Common ground for the BEC output.
- 4.0mm Plugs: Three output wires for connecting to the brushless motor.
5. Setup and Wiring
Follow these steps for initial setup and wiring of your ESC:
- BEC Voltage Selection: Before connecting, ensure the BEC gear switch is set to the correct voltage (5V, 6V, or 7V) required by your receiver and servos. The default setting is 5V.
- Motor Connection: Connect the three 4.0mm plugs from the ESC to the three wires of your brushless motor. The order of connection may affect motor rotation direction; if the motor spins in the wrong direction, swap any two of the three wires.
- Receiver Connection: Connect the PWM signal line (white wire) from the ESC to the throttle channel of your RC receiver. The red and black wires (BEC output and ground) also connect to the receiver to provide power.
- Battery Connection: Connect your 2-6S LiPo battery to the XT60 connector on the ESC. Ensure correct polarity.
Important: Please ensure all solder joints are insulated with heat shrink where necessary. Double-check all connections before applying power.
6. Operating Instructions
This section details the normal startup procedure, throttle range calibration, and programming steps for your ESC.

Image 6.1: Operational flow chart for Normal Start-up, Throttle Range Calibration, and Programming. This diagram illustrates the sequence of actions and corresponding ESC responses (beeps) for each procedure.
6.1 Normal Start-up
- Turn on your transmitter and move the throttle stick to the bottom (minimum) position.
- Connect the ESC to the battery.
- Wait for 2 seconds. The motor will emit a series of short "BEEP" sounds, indicating the number of LiPo battery cells.
- Wait for 1 second. The motor will emit a continuous long and short "BEEP" sound, indicating "No Brake" mode.
- The motor will then emit a long "BEEP" sound, indicating "Brake is available" mode.
- The ESC is now ready for operation.
6.2 Throttle Range Calibration
Calibrating the throttle range ensures the ESC accurately recognizes the full throttle input from your transmitter.
- Turn on your transmitter and move the throttle stick to the top (maximum) position.
- Connect the ESC to the battery.
- Wait for 2 seconds. The motor will emit a long "BEEP" sound, indicating that the full throttle position is memorized.
- Move the throttle stick to the bottom (minimum) position within 1 second. The motor will emit a short "BEEP" sound, indicating that the zero throttle position is memorized.
- The motor will then emit a series of short "BEEP" sounds, indicating the number of LiPo battery cells.
- Wait for 1 second. The motor will emit a continuous long and short "BEEP" sound, indicating "No Brake" mode.
- The motor will then emit a long "BEEP" sound, indicating "Brake is available" mode.
- The ESC is now ready for operation with the calibrated throttle range.
6.3 Programming
The ESC can be programmed via your remote control. Refer to the specific programming sequence for detailed options.
- Turn on your transmitter and move the throttle stick to the top (maximum) position.
- Connect the ESC to the battery.
- Wait for 2 seconds. The motor will emit two short "BEEP-BEEP" sounds.
- Continue to wait for 5 seconds. The motor will then emit a special tone ">>12321<", indicating that it has entered programming mode.
- Follow the specific programming instructions provided with your remote control or ESC for selecting and setting parameters.
