MXO-RACING FUTABA SFHSS Built-in Transponder & GYRO TOWER ANTENNA RECEIVER RXC52-SG&TP

MXO-RACING RXC52-SG&TP Receiver User Manual

Thank you for choosing MXO-RACING products. Please read this document carefully before use.

The RXC52-SG&TP is a miniature antennaless version surface receiver that integrates both Transponder and Mul_Gyro. It is a Futaba SFHSS compatible miniature high-speed surface receiver designed for 1:24/1:28 scale or MINI-Z models. The receiver’s output speed is as fast as 3.4ms, much higher than other receivers of the same protocol.

In order to ensure its working distance and response speed, the receiver features a high-gain LNA (Low Noise Amplifier), and optimized automatic LNA control logic in software. This enables the receiver to function effectively at both short and long distances. With its compact size and reliable performance, the RXC52-SG&TP is a perfect choice for hobbyists and enthusiasts using Futaba transmitters for their mini RC car projects.

LED Indicators

• Blue LED (Receiver status):

  • Flashing rapidly: Binding mode

  • Flashing slowly: Waiting for transmitter signal

  • Solid: Receiver is successfully connected and functioning normally

• Yellow LED (Gyro status):

  • OFF: Gyro is off or not present

  • Solid: Gyro is working, with brightness indicating direction:

    • Low brightness: Normal (NOR) direction

    • High brightness: Reverse (REV) direction

• Red LED (Transponder status):

  • OFF: Transponder is off or not present

  • Solid: Transponder is active

LNA Function

The LNA (Low Noise Amplifier) is an electronic component that enhances the receiver’s operating range and response speed, especially when used with transmitters that have lower output power. The LNA significantly improves handling and responsiveness, particularly beneficial for drifting and speed.

Binding Procedure

1. Power on the receiver.

2. Press and hold the BIND button until the blue LED flashes rapidly.

3. Power on the transmitter.

4. When the blue LED becomes solid, the binding process is complete.

Switch Between 3.4ms and 6.8ms Output Modes

The RXC52-SG&TP supports two output modes: 3.4ms and 6.8ms. Users can freely switch between these modes.

• For T7PX or T10PX transmitters:

  • SFHSS analog mode = 6.8ms

  • SFHSS digital mode = 3.4ms

• For other transmitters:

  • Select S-FH (NORM) = 6.8ms

  • Select S-FH (HIGH) = 3.4ms

Set Gyro Sensitivity and Direction

The RXC52-SG&TP uses the CH3 channel of the transmitter to adjust the gyro sensitivity and direction:

• When the CH3 signal is less than 1.4ms (Yellow LED high brightness), the gyro will turn to the left, and the smaller the CH3 signal width, the higher the sensitivity.

• When the CH3 signal exceeds 1.6ms (Yellow LED low brightness), the gyro will turn to the right, and the greater the CH3 signal width, the higher the sensitivity.

• A mid-range CH3 signal will turn off the gyro, and the Yellow LED will be off.

Set the End Point of the ST Channel

When using the built-in gyro, the gyro signal is superimposed on the ST channel. The output of ST is not limited by the End Point function of the transmitter. If the EXP is too large, the servo may become stuck. To prevent this, the End Point function has been implemented on the receiver:

1. Set CH3 on the transmitter to the midpoint to turn off the built-in gyro (Yellow LED OFF).

2. Adjust the ST channel of the transmitter to position the servo arm to the left, then press the BIND button. The Yellow LED will flash for 2 seconds and then turn off.

3. Move the ST channel to the right to the desired position, then press the BIND button. The Yellow LED will again flash for 2 seconds and turn off.

This process will set the left and right endpoints for the ST channel.

Set the Parameters of the Built-in Mul-Gyro

The Mul-Gyro is a complex gyro with up to 17 parameters to fine-tune its performance. Users can set the parameters using the MXO GUI tool, which is supported by the MX USB PG-ISP. This software allows for detailed adjustments of the gyro.

Edit Transponder Personal ID Number

The RXC52-SG&TP has a built-in transponder, and users can set their own personal ID using a visual ID editing tool. To do this:

1. Connect the receiver to the PC using the MX USB PG-ISP.

2. Open the MXO GUI software.

3. Use the ID editing tool to modify your personal transponder ID.
   

Online Firmware Upgrade

The receiver supports firmware upgrades through the MXO GUI. To update:

• The MX USB PG-ISP is required to connect the receiver to the PC.

• Ensure the transmitter is turned off before connecting the receiver to the GUI.
