RadioMaster Wireless Trainer Module

Introduction

This manual provides step-by-step instructions for setting up and troubleshooting the RadioMaster Wireless Trainer Module. The module enables an instructor (master radio) to wirelessly connect with a student radio, allowing for shared control of a model. The system is compatible with RadioMaster transmitters equipped with multi-protocol modules and receivers that support BUS output (e.g., SBUS, IBUS).

Note: Please ensure your radio is running the latest version of EdgeTX and that your internal ExpressLRS or MPM module is updated to the latest firmware. Keeping your firmware up to date will help ensure optimal performance and reliability.

Compatibility

Receivers: Any receiver that supports 5V and is capable of SBUS output, such as RadioMaster RP1, RP2, and R81 V2 models, can be used. Receivers from other manufacturers can also be used, provided they meet the required voltage and SBUS specifications.

Applicable Transmitter Models:

• Micro Module: TX16S, BOXER
• Nano Module: GX12, Zorro, Pocket, MT12

Note: Not compatible with TX12MKII.

Setup Overview

The setup involves configuring both the student (slave) and instructor (master) radios.

Setup on the Student (Slave) Radio

The student radio transmits control signals to the master radio via the Wireless Trainer Module.

1. Bind the Receiver: Bind the receiver to the student radio (slave) and ensure the receiver outputs an SBUS signal. [Receiver not included]
2. Solder Receiver Wires to Module:
   • Black wire: Ground (-)
   • Red wire: Positive (+)
   • Yellow wire: SBUS Signal
3. Insert Module into Radio:

   Insert the soldered receiver into the module and then insert the module into the instructor radio. Note that the Micro Module has two connectors:

   • For the Micro Module on TX16S: Use SBUS_A
   • For the Micro Module on BOXER: Use SBUS_B

   The Nano Module is applicable for GX12, Zorro, Pocket, and MT12 transmitters.

4. Configure Student Radio:

   Press the MDL button to enter the SETUP menu. Set Trainer to OFF.

Setup on the Instructor (Master) Radio

The instructor's radio is responsible for controlling the model and managing the trainer link.

1. Enable Trainer Function: Press the MDL button to open the SETUP menu. Set Trainer to Master/SBUS.
2. Assign a Trainer Switch: Press the MDL button to enter the SPECIAL FUNCTIONS menu. Assign a switch (e.g., SC switch) to toggle trainer mode.

Step 3: Verify the Trainer Link

Test the trainer functionality to ensure control is being passed correctly.

1. Press the SYS button to open the TRAINER menu on the master radio.
2. Move the sticks on the student radio and confirm corresponding channel movements on the master radio.
3. Toggle the assigned trainer switch (e.g., SC) to verify control swap between the instructor and student radios.

Troubleshooting Steps

• Check Binding: Ensure both radios are bound to their receivers using the correct protocol. The student radio should be bound to the receiver installed in the module. The teacher's radio should be bound to the receiver in the model.
• Verify Wiring: Ensure proper soldering of receiver wires (Black: ground, Red: power, Yellow: signal).
• Confirm RF Compatibility: The teacher and student radios do not need to use the same protocol, but they must be compatible with the trainer setup. For example, the teacher could be using an ExpressLRS radio bound to an ER6 receiver, while the student is using a FlySky radio with an SBUS receiver inside the trainer module. Ensure the trainer system is correctly configured to pass control between the radios.
• Check Trainer Mode: Verify the student radio is set to Trainer OFF and the master radio is set to Master/SBUS.
• Firmware Updates: Update radios and receivers from RadioMaster's support page to the latest firmware.
• Module Connection: Ensure the Wireless Trainer Module is securely inserted into the external module bay or BUS port.
