This is the third generation Jumper T12 Multi-Protocol Transmitter, now with upgraded digital hall sensor gimbals. As with all Jumper radios, it is very versatile coming with multi-protocol support and its extremely good value.

The radio’s biggest selling point is its support for pretty much any radio protocol. The T12 comes with the JP4-in-1 module that allows communication with a wide range of protocols such as Walkera DEVO, Spektrum DSM2/DSMX, Flysky, Esky, Frsky, WLtoys, Hubsan, Hisky, Futaba SFHSS Assan and most toy quads. For those using the TBS Crossfire or FrSky R9, it’s also compatible with those without any hardware modifications. There’s a JR style module bay in the back of the radio where you attach your own transmitter module.

The Jumper T12 Plus comes with hall sensor gimbals to provide smooth, accurate and precise control. There are also four 3-position switches, two 2-position switches and two potentiometers for controlling flight modes and gimbals. The transmitter can use up to 16 channels depending on the receiver type. Other features include a trainer port and USB port, which can be used to connect with a PC for flying a simulator.

The Jumper T12 transmitter is easy to use thanks to its clear 1.7inch LCD display and familiar software; it runs JumperTX firmware (based on the OpenTX Project) so people who use FrSky radios will have no problem navigating the settings menus. You can also run LUA scripts as it has a SD card slot.

Accessories include a neck strap, USB cable and battery trays. The radio can be powered from 4x AA / 2x 18650 cells or by a 2S LiPo or LiFe through the balance connector.

The compact form factor of the radio makes it very portable, it is about 2/3 the size of a traditional radio.

Does this radio have a memory for model setups?

If yes then how many models?

Can this number be increased and how is this achieved?


By admin on

Hi, you can store models on it, they don't specific a limit, as it's basically as many as you want. You can expand it even further should you need using the SD card.
