Full Instructions

Setup on the Student (Slave) Radio

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

Step 1: Bind the Receiver [Receiver not included]

Bind the receiver to the student radio (slave) and ensure the receiver outputs an SBUS signal.
Solder the receiver wires into the "Wireless Trainer Module":
- Black wire: Ground (-)
- Red wire: Positive (+)
- Yellow wire: SBUS Signal
Insert the soldered receiver into the adapter interface. Note that the Micro Module has two connectors.
- TX16S: Use SBUS_A
- BOXER: Use SBUS_B

Press the MDL button to enter the SPECIAL FUNCTIONS menu.
Assign a switch to toggle trainer mode (e.g., SC switch).

Step 3: Verify the Trainer Link

Press the SYS button to open the TRAINER menu.
Move the sticks on the student radio and confirm corresponding channel movements on the master radio.

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.

Additional Notes

Compatibility: Micro module works with RadioMaster TX16S, BOXER. Nano Module works with GX12, Zorro, Pocket and MT12 and receivers with a 5v SBUS serial output. (Not compatible with TX12MKII).
Pre-Flight Testing: Always test trainer functionality on the ground before flying.
Support: Visit RadioMasterRC.com for firmware updates and troubleshooting assistance.
