mTX is a fork of OpenTx 2.3.15.
Refer to the OpenTX wiki for information about setting up a tool chain for building OpenTX and other development/developer related topics.
Installation largely follows the installation of OpenTx 2.3.15. It involves three steps:
- Flash the mTX firmware binary appropriate for your radio to the radio. You can follow the standard OpenTx descriptions, except that you choose a different binary file. A convenient method for flashing can be using the OpenTx Companion.
- Copy the SD content required for OpenTx 2.3.15 to the radio's SD card. Follow the OpenTx descriptions for this step.
- Copy the SD card content provided in the SDCARD folder to the radio's SD card.
