Our stock is the latest V2 edition. It has a revised front plate with clear plastic surrounds for the gimbal (a nice touch for those DIYers who wish to add LEDs). Internally there’s an MCU upgrade. It now uses the STM32F407ZGT6 which has double the flash memory of the previous MCU. Thereโs also the addition of a fan for improved cooling of the ELRS module.
The difference between T20 and T20S is the gimbal. Theย Jumper T20 comes with the hall sensor gimbals,ย while the T20S comes with the upgrade RDC90 gimbal which uses the premium ALPS RDC90 sensors.
The Jumper T-20/S radio is distinctiveย in that it has a novel form factor. Jumper have designed this radio to be as compact as possible, while retaining all of the features you would expect toย find in a full size radio like a TX16S, such as full size gimbals; possibly giving you the best of both worlds.ย What’s more, The T20 is offered at an incredible price point.
The radio features a suite of programmable switches ofย all types.ย Allowing for endless programming options and beneficial for both drone and fixed-wing pilots alike. In particular, the 6 on/off buttons on the front of the radio are very handy for controlling flight modes. Jumper even provide a sticker sheet so that you can label their functions. Uniquely found on theย T20ย are two sliderย which resembled the engine throttle controls found in an aircraft, again fully programmable!
While the screen on the radio is small, it is OLED soย very sharp and bright. We found it perfectly usable and itโs a decision that has allowed the overall size of the radio to stay compact.
T20 radio is compatible with ExpressLRS receivers. ELRS is a control link that provides incredible range,ย reliability and very low latency – more info here. The ELRS transmitting module in the T20 is more powerful than most found in compact radios of its type. The ELRS module in the T20 can output up to 1watt power. It can continue operating at high power levels thanks to a built in fan which keeps the ELRS module cool.
By adding a 4in1 multi-protocol module (not included, available here) the T20 can also be used with regular 2.4G protocols like Frsky’s ACCST or Spektrumโs DSMX.ย Furthermore, the T20 can be used with other third party modules, such as TBS Crossfire. The radioย has an external XT30 7.4V power output on the back of the radio to power such modules.
The antenna on the radioย antenna is moveable. Itย has two adjustable jointsย which allow you to orientate itย in any direction. Handyย for matching the polarisation on your aircraftโs receivingย antenna to further enhance reception strength.
The radio is powered from two 18650/21700ย cells (not included) and can be recharged via its USB-C connector. Incidentally the USB-C can also be used to connect the radio to flight simulators should you wish to get even more use out of the radio.

Great radio. Compact and fits nicely in the hands when you don’t have big hands.
I find I comfortable to use thumbing or pinching.
Easy enough to set up with enough switches for everyone I want to do.
