Radiomaster has released the long waited TX12 radio. It is budget, compact size radio. Radiomaster TX12 inherits the design from the Jumper T12 radio, but adds some features, that can be found on Radiomaster radios. The radio is really small, fits into any backpack. The compact size in probably the most interesting feature of this radio, but nevertheless this radio has almost all the functions and features of the bigger, full sized radios.
Radiomaster TX12 has the metal roll wheel and full navigation controls. This is the first radio with black and white LCD that has full navigation buttons so far.
Radio has spacious battery compartment, fitting the two 18650 Lion batteries. Batteries can be internally charged via USB-C cable.
Unfortunately the TX12 has only the “lite” mutiprotocol module with one CC2500 RF chip, so the protocol selection is limited (FrSky D8/D16, Corona, Hitec, Futaba S-FHSS, RadioLink, Graupner HoTT and Redpine)
Also the decision to install the momentary push buttons instead of the 2-3 way switches is debatable and another design flaw for me.
Radiomaster TX12 radio has only single RF chip, therefore is supporting only FrSky, Futaba and some other protocols using CC2500 RF chip.
The battery compartment is large enough to accommodate the Lion 18650 batteries. The battery holder is also included.
Radiomaster TX12 has internal charging capability via USB-C type cable.
