ATA HOBBY DUMBORC X6FG 6-Channel RC Receiver with Built-in Gyro Instruction Manual

1. Introduction

The DUMBORC X6FG is a 6-channel 2.4GHz RC receiver featuring an integrated gyroscope for enhanced vehicle stability. This receiver supports two working modes: Normal mode and Gyro mode, allowing for precise control and correction of vehicle direction to prevent deviation and skidding. It is designed for easy binding and offers stable long-distance control with FHSS spread spectrum technology, ensuring reliable operation with a 400m control distance and 12ms fast response speed. The X6FG also includes a reverse polarity protection circuit to prevent damage and supports 4.8-10V DC high voltage servos.

Key Features:

• Built-in Gyro: Provides stability and directional correction.
• 6 Channels: Supports multiple functions for RC models.
• 2.4GHz FHSS: Ensures stable and interference-free communication.
• 4.8-10V DC: Supports high voltage servos.
• Reverse Polarity Protection: Safeguards the receiver from incorrect power connections.

3. Setup

3.1. Receiver Connection Diagram

Proper connection of the receiver to your RC model's components is crucial for correct operation. Ensure all connections are secure and correctly oriented.

Figure 3: Diagram showing connections from the receiver to the battery, ESC, motor, and servo. Channel 1 is typically for steering, and Channel 2 for throttle.

3.2. Binding Instructions

The receiver needs to be bound to your DUMBORC transmitter (X6, X4, X5, X6PM-350 series) for the first time. Follow these steps:

1. Ensure the transmitter and receiver are approximately 30-50 cm apart.
2. Power on the transmitter.
3. Power on the X6FG receiver.
4. Locate the tiny binding button on the receiver (next to the antenna).
5. Use a small, non-conductive tool (like a pen tip) to press and hold the binding button on the receiver.
6. The green LED indicator on the receiver will flash rapidly, indicating it's in binding mode.
7. Release the binding button once the LED starts flashing.
8. The LED will turn solid green, indicating successful binding.

4. Operating Instructions

4.1. Normal Mode and Gyro Mode

The X6FG receiver operates in two modes: Normal Mode (gyro off) and Gyro Mode (gyro on). The LED indicator on the receiver will show green for Normal Mode and red for Gyro Mode.

Figure 5: LED indicators for Normal Mode (Green) and Gyro Mode (Red) on the DUMBORC X6FG receiver.

4.2. Switching to Gyro Mode

To switch between Normal Mode and Gyro Mode:

1. Quickly press the binding button three times within one second.
2. The LED indicator will change from green (Normal Mode) to red (Gyro Mode).

Figure 6: Illustration showing how to switch between Normal (Green LED) and Gyro Mode (Red LED) by pressing the binding button three times.

4.3. Gyro Sensitivity Adjustment

Gyro sensitivity is typically controlled by Channel 6 on compatible DUMBORC transmitters. Turn the knob for Channel 6 to adjust the sensitivity. Turning clockwise increases sensitivity, and counter-clockwise decreases it.

4.4. Auxiliary Channel Usage

Auxiliary Channels 3 to 6 can be used to control additional devices such as lights or other accessories. These typically require connection to a switch relay board (not included).

5. Troubleshooting

5.1. Throttle or Steering Not Working

If your throttle or steering is not responding, ensure the 'sub-trim of Throttle' on your transmitter is set to zero. An incorrect sub-trim setting can prevent the Electronic Speed Controller (ESC) from recognizing the throttle input.

1. Locate the sub-trim adjustment for throttle on your DUMBORC transmitter.
2. Adjust the sub-trim to the '0' position.
3. If the issue persists, reset the transmitter, check the ESC, and calibrate it to ensure it is a two-way ESC with the correct working mode.

5.2. Gyro Direction Reversed

If the gyro correction is working in the opposite direction (e.g., turning left when the car drifts right), you can reverse the gyro direction:

1. Ensure the receiver is in Gyro Mode (red LED).
2. Quickly press the binding button twice within one second.
3. This action will reverse the gyro's correction direction.

7. Safety Information

Always operate your RC equipment responsibly. Observe the following safety guidelines:

• Ensure all connections are correct and secure before powering on.
• Never operate RC vehicles in crowded areas or near people, pets, or property.
• Keep hands and loose clothing away from moving parts.
• Always turn on the transmitter first, then the receiver. When powering off, turn off the receiver first, then the transmitter.
• Store the receiver and other RC components in a dry, safe place away from extreme temperatures.
