# Wireless Trainer

Wireless Trainer allows a radio with two modules - at least one being a MULTI-Module - to be used as a trainer, without the need for a wired connection to the student radio.

On the Trainer radio, the MULTI-Module is configured with a receiver protocol and the other module (which may also be a MULTI-Module) is bound to the model, and the Student radio is bound to the Trainer's MULTI-Module.

For a list of protocols supported for Wireless Trainer, see the Receiver Protocols section of the Supported Protocols page.
{% endhint %}

{% hint style="warning" %}
Wireless Trainer cannot be used on current FrSky radios due to a hardware limitation - they do not allow telemetry on the external module while the internal module is in use.

## Trainer Radio Setup

Configuring a full student/trainer setup is beyond the scope of this documentation.  You should be familiar with general trainer configuration before attempting to configure wireless trainer.

**Step 1:**  In Model Setup set the **Trainer Mode** to **Master/Multi**

**Step 2:**  Configure your MULTI-Module with one of the Receiver Protocols

{% hint style="success" %}
Telemetry must be enabled on the Trainer Radio. Wireless Trainer will not work if **Disable Telemetry** is checked.
{% endhint %}

## Student Radio Setup

**Step 1:**  Configure your radio to use the TX version of the Receiver Protocol which was configured on the Trainer Radio.

## Binding

Once the models are configured on both radios, they need to bind.  Binding is logically the same as any transmitter/receiver combination.

{% hint style="success" %}
Any other RF modules should be disabled when binding the trainer and student radios.
{% endhint %}

**Step 1:**  On the Trainer Radio, initiate binding on the RF module which is configured with the Receiver Protocol

**Step 2:**  Initiate binding on the Student Radio
