EdgeTX operating system

Pre-installed with EdgeTX, the MT12 features cutting-edge software to match its class-leading hardware. RadioMaster works closely with the EdgeTX team to develop new features and optimize the user experience for surface models. We will continue to contribute and support projects like EdgeTX, ensuring that the concept of open standards continues.

Available with ExpressLRS and 4in1 versions

In addition to the popular internal 4-in-1 multi-function module, the MT12 is also available with an internal 2.4 GHz ExpressLRS (ELRS) module. Designed to provide reliable control over long distances, ultra-low latency and high refresh rates. ELRS is a revolutionary open source protocol that is taking the R/C industry by storm.
