RADIOMASTER MT12 4-in-1 FCC Surface Transmitter w/R85C Receiver

The RADIOMASTER MT12 is a pioneering open-source surface radio, and the first surface radio officially supported by the EdgeTX and ExpressLRS multi-module project. The MT12 is available as either an ELRS or 4-in-1 multi-module version (see specs) and boasts 10 physical inputs, and the capability to handle either 16 or 32 channels (4-in-1 version only). The 4-in-1 system offers one transmitter for all of your cars, boats, or anything else that operates on the surface. The internal RF system has protocols, for many popular brands of cars and receivers (see below for the web address to the supported protocols). Each version is also available in either an FCC version or a European LBT version, please check the specifications below for the supported protocol.

The EdgeTX system is preinstalled and the MT12 has cutting-edge software fit for its class-leading hardware. RADIOMASTER works closely with the EdgeTX team to develop new features and optimize the user experience for surface models. RADIOMASTER will also continue to contribute and support projects like EdgeTX, ensuring the concepts of open standards are carried forward, for more information, please visit https://edgetx.org/

Just a few of the features of the MT12 include a standardized button layout and CNC menu wheel, adjustable throttle trigger to suit your driving style, adjustable wheel tension, Hall sensors for accurate inputs and precise centering, 5 trim buttons, and an external NANO module. Included with the transmitter is the R85C receiver, which is compatible with FrSky D8/D16 and Futaba SFHSS RADIOMASTER protocols, it also offers a receiving range that is suitable for most RC modeler's needs. It has a built-in TCXO (temperature compensated Xtal Oscillator), which ensures high stability and accuracy in frequency control whilst compensating for temperature variations.

Note: The R85C receiver is suitable only for RADIOMASTER Multi-Protocal radios with the ability to fine-tune protocols, it is not compatible with FrSky radios.

The MT12 is primed for a wide array of surface models, from cars and trucks to boats and much more. Featuring extensive customizability and a versatile operating system, the MT12 stands out as a highly configurable surface radio, prepared to excel in virtually any scenario.
