RadioMaster TX12 Mark II Radio Controller

Introducing the RadioMaster TX12 Mark II, the perfect compact radio controller that combines a traditional form factor with modern, high-performance features. This version comes with a powerful internal ExpressLRS (ELRS) module and upgraded V4.0 Hall Gimbals, all running on the cutting-edge EdgeTX firmware. For pilots who want a smaller, lighter radio without sacrificing features or comfort, the TX12 MKII is the ultimate choice.

Compact Size, Full-Size Features

The TX12 MKII offers the comfortable feel of a traditional radio in a more portable package. It’s packed with features, including high-precision Hall gimbals for smooth and accurate control, a full suite of switches and sliders, and a standard JR-compatible external module bay for maximum versatility. It’s everything you need for your FPV drone, plane, or other RC vehicle.

Integrated ExpressLRS Performance

This version of the TX12 features a built-in ELRS 2.4GHz module. ExpressLRS is the leading open-source radio link, renowned for its incredible range, low latency, and high refresh rates. With this powerful system integrated directly into the radio, you get a top-tier control link for your FPV drone right out of the box, with no external module required.

Mark II – The Best Got Better

The Mark II is a significant upgrade over the original TX12. It features a more powerful STM32F407 main processor for a smoother EdgeTX experience, improved Hall gimbals with better centering, faster QC3.0 USB-C charging, and a redesigned rear case with more comfortable grips. It’s a refined and reliable drone part for your FPV setup.
