Configuration

This guide explains how to configure trim switches, 3-position switches, standard buttons, and export model configurations using EdgeTX Companion on the Zorro RadioMaster transmitter.

The controller is supplied pre-configured, but this guide can be used for setting up the controller in case of a failure.
