The RADIOMASTER TX12 is a compact, low-cost, OpenTx radio that has many great features. Being compact, it is about two-thirds the size of a traditional transmitter, has a removable antenna, and a folding carry handle, which makes it the perfect option for traveling. Despite its smaller size, it is comfortable to hold due to its well-designed case and improved ergonomic hand grips.

This MKII version with upgraded STM32F407 MTU has the cutting-edge EDGETX software pre-installed. This open-source firmware is highly customizable to allow users to configure their transmitters through the supplied USB-C data port to adjust the settings for their individual preferences and specific needs. EdgeTX supports a wide range of RC protocols and is a versatile and powerful tool which makes it extremely popular with the RC community. RADIOMASTER works closely with the EdgeTX team to develop and optimize the user experience and will continue to ensure that the concept and standards are carried forward into the future.

The transmitter has various switches and sliders, it also has two momentary switches which gives you lots of options when it comes to programming your models. There is a 128x64 monochrome LCD display screen for status and programming, plus it can handle up to 16 channels depending on the receiver used. The actual programming of the transmitter is a very simple affair with the easy-to-use system/page buttons and the menu scrolling wheel. Also included is a built-in USB-C charging system for 2 x 18650 cells, high precision gimbals, an external SD card slot, built-in voice support, and much much more. The TX12 is available in either an FCC version or a European LBT version, please check the specifications below for the supported protocol.

Overall this is an easy-to-use transmitter that removes the need for you to have lots of different types of transmitters at your disposal. This one unit if used with some additional modules will operate just about all the different protocols on the market today.
