2. Safety Precautions

• Always disconnect the battery from the ESC when not in use to prevent accidental motor activation.
• Ensure all connections are secure and properly insulated to avoid short circuits.
• Never operate the ESC with damaged wires or connectors.
• LiPo batteries require careful handling. Follow all manufacturer guidelines for charging, discharging, and storage.
• Keep hands and loose clothing clear of the propeller or moving parts when the motor is powered.
• The ESC can become hot during operation. Allow it to cool before handling.

3. Product Features

• High Performance MCU: Equipped with an 8-bit C8051 core, operating up to 50Mhz, ensuring precise control and strong anti-interference.
• Wide Voltage Support: Compatible with 2-6S LiPo batteries.
• Waterproof Design: Capable of short-term operation in water. (Refer to Maintenance section for post-use care).
• Built-in BEC: Integrated 5.5V 5A switch BEC provides stable power for servos and receiver.
• Multiple Protection Functions: Includes power-on safety, low voltage, start-up, overheat, and throttle signal loss protection.
• Efficient Cooling: Water-cooled aluminum heat sink effectively manages temperature rise.
• User-Friendly Programming: Supports programming via a dedicated programming card (sold separately) and features a cycle programming menu.

5. Setup and Wiring

Proper wiring is crucial for the safe and efficient operation of your ESC. Follow these steps carefully:

1. Motor Connection: Connect the three motor wires to the three 4.0mm banana head connectors on the ESC. The order of connection may affect motor rotation direction; this can be adjusted later if needed.
2. Battery Connection: Connect your 2-6S LiPo battery (equipped with an XT60 connector) to the XT60 connector on the ESC. Ensure correct polarity (red to positive, black to negative).
3. Receiver Connection: Plug the small servo-style connector from the ESC (BEC output) into the throttle channel of your RC receiver. This provides power to the receiver and transmits throttle signals.
4. Mounting: Securely mount the ESC in your RC boat, ensuring adequate airflow for cooling, although the unit is water-cooled. Position it to prevent excessive vibration.

6. Operating Instructions

Once the ESC is correctly wired and mounted, follow these steps for operation:

1. Transmitter On: Turn on your RC transmitter and ensure the throttle stick is at its lowest position (zero throttle).
2. Connect Battery: Connect the LiPo battery to the ESC. The ESC will emit a series of beeps indicating cell count and readiness.
3. Power-On Safety: Due to the built-in power-on safety feature, the motor will not start immediately, regardless of the throttle position. This prevents accidental starts.
4. Throttle Calibration (if needed): If the motor does not respond correctly to throttle input, you may need to calibrate the ESC's throttle range with your transmitter. Consult your transmitter's manual for specific calibration procedures. Generally, this involves powering on the ESC with the throttle at maximum, then moving it to minimum when prompted by beeps.
5. Operation: Slowly advance the throttle stick on your transmitter. The motor should respond smoothly.
6. Shutdown: Always reduce throttle to zero, then disconnect the battery from the ESC first, before turning off your transmitter.

7. Programming the ESC

The ApisQueen 50A ESC offers customizable settings to optimize performance for various applications. Programming can be done via a dedicated programming card (purchased separately) or through the transmitter's throttle stick using the cycle programming menu.

7.1. Using a Programming Card

For detailed programming options and ease of use, a programming card is recommended. Refer to the programming card's instruction manual for specific steps. Typically, you connect the ESC's signal wire to the programming card, power the ESC, and then select desired parameters.

7.2. Cycle Programming Menu (Transmitter Method)

The ESC features a cycle programming menu accessible via your transmitter's throttle stick. This method allows adjustment of basic parameters such as:

• Start Mode (e.g., soft start, normal start)
• Low Voltage Protection Threshold
• Motor Timing
• Brake Type

To enter the programming mode, power on the ESC with the throttle stick at maximum. After a specific sequence of beeps, move the throttle to the middle or minimum position to select options. A detailed sequence of beeps and corresponding settings will be provided in a separate programming guide or can be found on the manufacturer's website.

8. Maintenance

To ensure the longevity and optimal performance of your ApisQueen 50A ESC, observe the following maintenance guidelines:

• Water Exposure: While the ESC features a waterproof design, it is intended for short-term exposure. If the ESC comes into contact with water, it is crucial to thoroughly dry the unit before its next use. Failure to do so can lead to corrosion and damage.
• Cleaning: Regularly inspect the ESC for dirt, debris, or corrosion. Clean the exterior with a soft, dry cloth. Avoid using solvents or harsh chemicals.
• Connector Inspection: Periodically check all connectors (XT60, banana heads, BEC plug) for signs of wear, damage, or loose connections. Replace any damaged components immediately.
• Storage: Store the ESC in a dry, cool environment away from direct sunlight and extreme temperatures.
