Jumper T12 Pro 2.4GHz 16CH OpenTx Multi-Protocol Radio Transmitter

Jumper T12 Pro Hall 2.4GHz 16CH OpenTx Multi-Protocol Radio Transmitter

Jumper Radios

This is the fourt generation Jumper T12 Multi-Protocol Transmitter. The main changes include moving the multiprotocol module to within the radio so than the exeternal JR module bay is now free to use with a long radio RF module like TBS Crossfire or FrSky R9. The LCD screen is bigger, up from 1.7inch to 2.4inches and the casing is now wrapped in a carbon fibre style trim. Best of all the radio now has internal charging circuit to charge the batteries via USB.

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, 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 Pro 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 2.4inch LCD display and familiar software; it runs OpenTx firmware 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 18650 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.

As with all Jumper radios, it is very versatile coming with multi-protocol support and its extremely good value.

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.

Can I clarify a couple of discrepancies in the description: (1) The screen is 2.4" not 1.7"; (2) Does the radio come with OpenTX or JumperTX? (3) Is it supplied with a battery tray for (a) 4 x AA or (b) 2 x 18650's? (4) Could you recommend a suitable 2s Lipo for the T12? (5) What is the warranty period? (6) Do you stock the Jumper zipper case? Sorry for this list, but there are lots of discrepancies in the Jumper description and the manual, which also mentions DeviationTX ! Thanks for your help.

Sorry for the discrepancies, we were updating the product today to the new Pro version. 

1. The screen is 2.4"

2. Runs OpenTX

3. Comes with a battery tray for two 18650 cells.

4. We have this 2S LiPo which fits okay - here

5. 6 months

6. Case is going to be listed here.

Hi, can this be made mode 1, or have both sticks return to centre?

By Brian Lee (not verified) on

Yes it can.

It can be supplied as either mode 1 or mode 2 (although my mode 1 was special order from the manufacturer). It is not difficult to convert from one mode to the other yourself.
