Radiomaster TX12 Mark II Radio Controller (M2) ELRS

RadioMaster TX12 Mark II ELRS is an updated version of the popular compact radio controller, combining portability, high performance, and advanced technology for FPV pilots of all skill levels.

The controller is equipped with a built-in ExpressLRS (ELRS) transmitter, providing ultra-low latency, high refresh rates, and impressive long-range signal reliability. Thanks to an optimized chipset, the internal module features upgraded cooling. The Hall effect gimbals (Hall V4.0) guarantee maximum precision, smooth stick travel, and long-lasting durability compared to standard potentiometers.

The radio runs on the cutting-edge EdgeTX operating system, unlocking endless possibilities for customization, mixing, and flight mode configurations. A standard JR module slot on the back panel allows the installation of external long-range modules (such as TBS Crossfire or alternative frequency modules).

The body features improved ergonomics, removable stick ends, and a convenient folding carry handle. Power is managed via a spacious battery compartment, and the USB-C (QC3.0) charging port allows for fast internal charging without removing the batteries, as well as a direct connection to a PC for FPV simulator training.
