1. Introduction
This manual provides detailed instructions for the safe and efficient operation of your ApisQueen A300 2.4 GHz 6-Channel Remote Control System. Designed for RC boats, this system includes a transmitter (remote control) and a 6-channel receiver, offering precise control and various programmable functions. Please read this manual thoroughly before use to ensure proper setup and to maximize your experience.
2. Safety Information
- Always operate your RC model in open areas, away from people, animals, and obstacles.
- Ensure all connections are secure before powering on the system. Loose connections can lead to loss of control.
- Keep the remote control and receiver away from water unless explicitly stated as waterproof. The A300 remote control is NOT waterproof, but comes with a silicone waterproof case for protection. The receiver has not undergone waterproof treatment and requires attention to waterproofing during use.
- Do not expose the battery to extreme temperatures or direct sunlight.
- Use only the specified charging method for the remote control's built-in lithium battery.
- The antenna of the receiver needs special protection to prevent breakage.
- The installation position of the receiver needs to pay attention to magnetic field interference.
- The input voltage of the receiver should not exceed 12V. Use a regulated power supply for input.

5. Setup
5.1 Charging the Remote Control
The remote control has a built-in 1200mAh lithium battery. To charge:
- Connect the provided charging cable to the remote control's charge port.
- Connect the other end of the charging cable to a 5V mobile phone charger (not included).
- The charging port has an indicator light: red light indicates charging, green light indicates a full charge.
- Turn off the remote control power during the charging process.
5.2 Receiver Connection
Connect your ESCs, servos, and other components to the receiver's PWM channels (CH1-CH6). Ensure correct polarity for all connections.
5.3 Code Matching (Binding)
To establish communication between the transmitter and receiver:
- First, power on the receiver.
- Press the BIND button on the receiver again.
- Finally, turn on the transmitter power.
Receiver Light Status:
- Green light flashing slowly: No signal.
- Green light flashing fast: Frequency matching.
- Green light remains on: Connected.
5.4 Servo Mode Setting
The receiver supports both digital and analogue servo modes:
- Press and hold the BIND button on the receiver for 3 seconds. The blue light of the receiver will turn on.
- Blue light on: Digital servo mode (PWM output frequency: 333HZ, Pulse width of digital servo: 500µs-2500µs).
- Blue light off: Analogue servo mode (PWM output frequency: 50HZ, Analogue Servo Pulse Width: 1000µs-2500µs).
6. Operating Instructions
6.1 Hybrid Control
The remote control offers two hybrid control modes: 1/2 channel hybrid control and 3/4 channel hybrid control. This allows for combined control of channels by pressing specific keys.
Setting Method:
- Ensure the remote control is off.
- Press and hold the channel button labeled '3' first, then turn on the power switch of the remote control.
The display icon will indicate the selected hybrid control mode. Switching between mixed control modes is done by cycling through this step.

6.2 Channel Reverse
This function allows you to reverse the direction of channels 1 and 2.
Setting Method:
- Ensure the remote control is off.
- Press and hold the channel button labeled '4' first, then turn on the power switch of the remote control.
- Flip the joystick of channel 1 or channel 2 (in any direction) to switch between the positive and negative positions of the corresponding channel. The screen will flash during the channel switching process.
Note: Only one channel can be set in both positive and negative directions at a time.
6.3 Rudder Setting (Channel Stroke Adjustment)
The stroke of each channel of the remote control can be adjusted for precise control.
Setting Method:
- Ensure the remote control is in shutdown status.
- Press and hold the channel key labeled '5' first, then turn on the power switch of the remote control.
- By pressing the corresponding channel button, you can adjust the stroke amount. The adjustment process allows you to observe the rudder's stroke amount in real-time.
- Long press the channel key '5' to exit the setup.
Note: The default stroke amount is the maximum. There are 10 segments from the maximum stroke amount to the minimum stroke amount, which can be adjusted in cycles.
6.4 Locking Function
To prevent accidental operation, the remote control can lock the 1-channel and 2-channel fine-tuning keys.
Setting Method:
- Ensure the remote control is off.
- Press and hold the channel button labeled '6' first, and then turn on the power switch of the remote control.
The opening and closing of the lock are indicated by icons on the display screen.
6.5 Automatic Shutdown
To prevent forgetting to shut down the remote control, it will enter the shutdown state after 15 minutes without any operation. An audio prompt will sound 1 minute before the shutdown.
6.6 Constant Speed (Cruise Control)
This function allows for maintaining a constant throttle speed.
Setting Method:
- Press the 'OK' button on the remote control to adjust the throttle speed.
- Increase the throttle lever forward by a constant speed of 10 units each time. A 'drip' sound prompt will be heard for each increase.
- Decrease the throttle lever backward by a constant speed of 10 units each time. A 'drip' sound prompt will be heard for each reduction.
6.7 Loss of Control Protection
Loss of control protection is a safety feature that protects the throttle channel when the receiver cannot receive a signal from the transmitter. In such a case, the throttle channel will automatically revert to a default or pre-set value.
Setting Method:
- After setting up and successfully code matching the transmitter and receiver.
- Turn off the remote control first.
- Press and hold the 'OK' button, then turn on the power switch of the remote control. The remote control screen will flash and be accompanied by a sound prompt, indicating entry into the setting state.
- At this point, the throttle channel can be set for runaway protection (e.g., setting it to neutral or minimum throttle).
- After setting, press the 'OK' button again to exit.
7. Maintenance
- Keep the remote control and receiver clean and dry. Wipe with a soft, dry cloth.
- Avoid dropping or subjecting the devices to strong impacts.
- Store in a cool, dry place when not in use.
- Regularly check all cables and connectors for wear or damage.
- Ensure the silicone waterproof case is properly fitted to the remote control before use in environments where water exposure is possible.
8. Troubleshooting
8.1 No Signal / Receiver Light Flashing Slowly
- Ensure both the remote control and receiver are powered on.
- Repeat the code matching (binding) procedure as described in Section 5.3.
- Check for any obstructions or excessive distance between the transmitter and receiver.
- Verify the receiver's antenna is not damaged or obstructed.
8.2 Loss of Control During Operation
- Check battery levels of both the remote control and the RC model.
- Ensure the receiver's input voltage is within the specified range (DC 4V-9V).
- Verify that the loss of control protection is correctly configured (Section 6.7).
- Avoid operating in areas with strong magnetic interference.
8.3 Remote Control Not Responding
- Check if the remote control's battery is charged.
- Ensure the remote control is powered on.
- If the fine-tuning keys are locked, unlock them as described in Section 6.4.
