Review: Jumper T-Pro Radio Transmitter

by Oscar
Jumper T Pro Radio Transmitter Hand Hold

The Jumper T Pro is an extremely portable gamepad style radio. It comes with OpenTX firmware, hall sensor gimbals and built in multi-protocol module. Affordable and compact but still powerful enough to be your daily driver.

Where to Buy?

The radio alone is only $100, $115 with ExpressLRS TX module, which is a really good deal if you ask me.

Mine is the ExpressLRS bundle which includes the AION ELRS TX module and Nano ELRS RX. I will talk more about ExpressLRS later in this review, but now let’s focus on the radio.

The Jumper T-Pro transmitter comes in a very nice soft shell carrying case.

Beware that batteries are NOT included. It takes two 18650 Li-ion cells. I recommend Panasonic NCR1650B 3400mAh (get them from Amazon), in my testing they performed the best.

Closer Look

The Jumper T-Pro has a multi-protocol module built-in, meaning you can use this radio to control many FPV drones on the market, including the popular Frsky D8, D16, Flysky AFHDS2A etc.

Not only that, it also supports external RF module! It comes with a mount that you can install, and it supports “Lite modules” (not Standard size JR module). This is great if you want to run TBS Crossfire, Tracer or ExpressLRS.

The Jumper T-Pro has improved from the T-Lite (see my review here) considerably in many aspects.

The new design seems to be inspired quite significantly by the TBS Tango 2 (screen location, buttons, scroll wheel, antenna shape etc) . I actually prefer this change over the T-Lite, it looks more professional and is definitely more user friendly and intuitive to use.

The T-Pro is almost the same size (maybe just a little larger) than the T-Lite. Here’s a size comparison between the T-Pro and the XBox gaming controller.

Jumper T Pro Radio Transmitter Size

This transmitter has pretty good ergonomics. It’s great for thumbers, not so much for pinchers though.

The gimbals are hall sensor gimbals, they are very smooth and more durable than potentiometer gimbals. The sticks can be extended by twisting the stick ends, but that’s as short as they can get in the picture. I wish they could be even shorter :) It uses M3 stick ends, if you want upgrade this is a good option:

The sticks feel quite decent, maybe a little too loose out of the box for my taste, and the gimbal springs just needs a little tightening perhaps.

Additionally, it has trim buttons! It’s awesome for guys who fly wings and planes :)

Jumper T Pro Radio Transmitter Gimbals

The Jumper T-Pro doesn’t have as many switches as a full size radio like the Jumper T16 or Radiomaster TX16S. It only has two 3-position switches, two momentary switches, two sliders and 6 flight mode buttons (only one button can be turned on at a time). Is this enough? I’d say yes for casual flying. For me personally, I use one 3-position switch for arming, the other for flight modes, and the momentary buttons for beeper and turtle mode. If you want to use Rescue mode and other stuff, I am sure it’s doable with some more careful arrangement.

The position of the switches are easy to access, I don’t have any complaints there.

The external antenna is quite bulky, but fortunately it’s foldable. It’s for the multi-protocol module inside the radio. However I wish it could be rotated 90-degree so it points vertically, in some cases this provides better signal. And if it could be removed while using an external RF module, that would be nice.

Note that there is an SD card slot in front of the antenna. It’s for OpenTX content such as images, scripts and audio files. It’s not necessary but will make your experience much better, so I do recommend getting one. The radio doesn’t come with an SD card so you’d have to buy one yourself. Here I explain how to update SD card content.

Jumper T Pro Radio Transmitter Switches

On top, there is a 3.5mm trainer port, USB-C connector for FPV simulators and battery charging as well as accessing bootloader mode and connecting to OpenTX Companion. The button in the middle is the boot button, if you want the radio to go into bootloader mode when connecting the USB cable, you have to hold down this button first before powering on.

The screen is of decent quality, it’s small but readable. The only complain I have is the uneven backlight. The T-Pro also has a speaker and haptic feedback (vibration) built-in.

Back of the radio:

Jumper T Pro Radio Transmitter Back Grip

By removing the rubber grips on the back, reveals the battery compartments. The previous Jumper T-Lite only takes a single 18650, in the T-Pro it actually takes two, so battery life is significantly prolonged.

The double batteries also makes the T-Pro heavier, but in a good way in my opinion. It just feels better in my hands because of the extra weight, and the grip feels more solid too.

Without battery, the T-Pro weighs 238g. With two 18650 it weighs 330g.

You actually need both batteries inserted in order to power on the radio, one battery won’t work.

Since the T-Pro is powered by two batteries in series (much higher voltage), it has integrated voltage regulators to provide enough current for higher power external TX modules without mods, such as the 1W TBS Crossfire module V2 Nano.

The 18650 can be charged via the USB-C port, takes about 2 hours to fully charge.

First Flight Setup

If you are totally new to OpenTX, here’s how you can setup the Jumper T-Pro for your first flight the fastest.

They have created a model for you in the radio, so all you have to do is to select the right protocol in the radio so that you can bind it to the FPV drone you are flying.

In this example, I am flying the Emax Tinyhawk 3, which uses Frsky D8 protocol.

In Model Setup, scroll down to External RF, make sure it’s switched off.

In Internal RF, select “Multi” for Mode, and “Frsky D” for Type, “D8” for subtype.

Then you can click the “Bind” option to begin binding to the drone. (you also need to put the drone in bind mode, simply go to Betafilght, enter “Bind_RX” in CLI).

That’s it! Now go to the Receiver tab in Betaflight, and check if the channels are responding correctly to your sticks. You might need to change Channel Map to AETR if the channel order is wrong.

Jumper T Pro Radio Transmitter Internal Rf Frsky D8 Setup Out of the box, the switches are not assigned to the channels, so you won’t be able to arm the drone, or change flight modes.

To assign switches, go to the Mixes page, and assign any switches you want to CH5, CH6, CH7 and CH8. You can follow my step by step tutorial on how to do it.

ExpressLRS Module Installation

Here’s a closer look at the ELRS TX module and RX that comes with my Jumper T-Pro radio, and how to install it.

ExpressLRS is an awesome and affordable opensource radio system. If you haven’t heard about it yet, make sure to check out my article.

Jumper Expresslrs Elrs Tx Module Receiver Unbox

SMA connector.

Jumper Expresslrs Elrs Tx Module Antenna

USB-C connector for firmware updates. It also has WiFi built-in so you can upgrade it that way too.

Jumper Expresslrs Elrs Tx Module Usb C

The Nano ELRS receiver is tiny.

Jumper Expresslrs Elrs Rx

Here’s the manual for the nano ELRS receiver.

Jumper Expresslrs Elrs Rx Manual

First of all, install the external module mount. Drill 3 holes on the back of the radio. They already marked the position of the holes for you. I used a 1.0mm drill bit and it worked great.

Insert the ribbon cable from the mount, into the connector on the radio, then secure it with 3 screws.

Jumper T Pro Radio Transmitter Install Expresslrs Elrs Tx Module So far I am loving the Jumper T-Pro. For $100 this is really a good compact radio you can easily take everywhere.

Hardware Bug in the Internal ELRS Version

There’s a new version of the T-Pro that comes with internal ELRS module (instead of the multi-protocol module). However it has a hardware bug that can potentially brick the internal module from a failed firmware flash.

Statement from ELRS Dev, Alessandro Carcione, on ELRS Facebook Group:

This is a disclosure statement regarding the Jumper T-Pro with internal 1W ELRS module. Jumper did not consult with the ELRS team when designing this product. As a result, there is no provision for recovery from a failed flash of the internal module. Unlike the Zorro for example, where the internal module which can be flashed via EdgeTX passthrough and is impossible to brick.

This means a failed WiFi upgrade on the internal T-Pro module requires a complex procedure and extra hardware to recover ( It is not possible to add passthrough flashing as a feature on the T-Pro as Jumper has not wired up the appropriate pins. If Jumper had collaborated with us, this could have been avoided in the design phase, but it was not. We are currently looking into options, but it will be unavoidable that you will have to open the radio at least once if you are affected by this issue.

We encourage all manufacturers to engage in discussion with us when designing new products.

I have this radio. Changed from X-Lite OG to this for ELRS. WORST RADIO IN MY HANDS EVAR!! Plastic AIDS gimbals get 1 star.. Sticks and throws are TALL AND LONG! They are also pressed into the plastic gimbal bodies and they can pull out or twist!! Mine wont charge via USB.. It only powers on and then runs the batteries out.. Battery life has ALWAYS BEEN A FAIL! Cant make it through a tinywhoop event without needing a recharge… Avoid

Kyle 22nd November 2023 - 4:19 am

How do you figure out expected battery life on Transmitters?

Jumper T Pro V2 OLED ELRS with say two Radiomaster 18650 2500mAh?

Guillaume 24th August 2023 - 10:08 am

Hello Oscar, Just wondering if you would know (better) replacement gimbals available on the market for this radio ? I think it is avery handy radio but those (stock) gimbals are really poor .. Thank you in advance !

Oscar 25th August 2023 - 2:38 pm

As far as I know, there’s no other gimbals that are direct replacement for the T-Pro. I’ve seen people modifying their T-Pro to fit the AG01 Mini gimbals, but it requires some DIY and doesn’t seem to be easy to do.

Guillaume 26th August 2023 - 9:52 am

Ok, thank you for the reply ! I might have a look at the Zorro which looks more « pro » than the T-Pro ! ;-)

john li 3rd June 2023 - 1:13 pm

Does the potential bricking issue still apply for the version with the built-in ELRS module?
Albert Kim has a video which I think says you can get EdgeTX passthrough working on the radio:
The ELRS wiki also doesn’t mention this bricking issue:

Oscar 3rd June 2023 - 2:05 pm

Don’t take anyone’s words for it, this is a hardware design issue entirely on Jumper’s side. You should contact Jumper for a solution if you own this radio. If you are considering buying this radio, you should contact Jumper to make sure they’ve resolved this issue in the latest batch. I haven’t tested the latest batch so I cannot confirm.

Wolfgang 28th May 2023 - 11:51 am

Hi Oscar,

what do you think: is ist possible to replace the display in the V1 with this display?
Size and resolution sounds ok.


Oscar 28th May 2023 - 12:09 pm

I am not entirely sure to be honest.

D3IV 6th April 2023 - 11:01 pm

Update with the Jumper T-Pro V2?? ELRS version

saikek 19th May 2023 - 8:26 am

Yeah, those OLED display + extra 2 buttons

Gabe 20th March 2023 - 7:22 am

Is it possible to change the t pro to mode 3? I’ve looked everywhere and I can’t find anything about it. I’m currently deciding between t pro and zorro, leaning towards t pro for battery life and size

Oscar 21st March 2023 - 3:23 pm

I am not 100% sure as I haven’t tried to change it to mode 3, but it looks like you just need to swap the metal plate that is used for giving throttle resistance and install it on the other gimbal, with the spring on the other gimbal.

Gabe 22nd March 2023 - 10:46 am

Thanks so much for the help. Sorry for replying twice, I just wasn’t sure if you would see this on an old post.

Also just some feedback it might be helpful if you added an email notification when you reply. Thanks again

Enrique Paz 16th December 2022 - 9:49 pm

I’m loving this device so far it was packaged in a very high quality manner. My only problem is that someone forgot to pack me some screws to mount my lite backpack module. I’m off to the hardware store.

jahoora 12th December 2022 - 2:32 pm

Hi, can you help me please. i have elrs version and i want to add external multi protocol modul. I finded some variants, but cant understand what multiprotocol modul is work with jumper t pro and installed without problems. Thanks!

Oscar 12th December 2022 - 4:29 pm

something like this should work fine:

jahoora 13th December 2022 - 2:04 pm

Thank you!

Alexander 21st October 2022 - 7:24 pm

Thanks for these clear explanations :)

has anybody tried the student/rtainer-mode with cable with those two senders?

Shaurya 4th October 2022 - 4:35 pm

Hey Oscar, I purchased a jumper t-pro, however when trying to bind one of the pins of the module bay broke, could you make a guide on repairing the module bay in case the pins break.

Max 11th July 2022 - 2:50 pm

Hello Oscar,

thank you for your review of the Jumper T-Pro.

I have questions about the charging time. Have you verify the charging time by yourself?

I got brand new Jumper T Pro from Banggood and the max charging current is 300mA.
I tested several USB Chargers and cables, the max current is 300mA.

I asked the Jumper Support if the max. current of 300mA is normal. The support told me that the max. current is about 200-300mA.
With this current it is impossible to charge a the batteries in 2 hours ;)

Andrew Roberts 5th June 2022 - 11:27 am

What a great review, Thank you. I wish I had seen this prior to buying. But I am happy with my T Pro. I have one question. Do you have to bind drones again when switching models? I have a UZ65 and bought a modula 6. I made a copy of my model and used it to bind to the new drone. All.was good, but on switching back to the UZ65, it is unbound. Is this a limitation of the radio? Thank you.

Oscar 5th June 2022 - 12:07 pm

No you shouldn’t need to rebind just switching between models. Are you using ExpressLRS on those models? You need to power on the radio within 20 seconds of powering on the quad or the receiver will go into WiFi mode.
Also, Make sure the receiver ID under Internal RF in model settings are set to 0 if you are not using model match. If you don’t know what model match is then you are probably not using it, just set receiver ID to 0 in your models.

fatih 3rd May 2022 - 3:37 pm


ı bought internel ELRS version of this tx . I have some issues cant find solution . Can you help me please.

when ı set it up to hight tx power (250 mw or 500 mw ) . Speaker have some parazite sound . and pitch and roll values on betaflight shaking badly . when ı reduce the tx power it is getting well .

Oscar 3rd May 2022 - 4:06 pm

It sounds like hardware related, i think you should contact Jumper customer service about this issue.

Alex 21st May 2022 - 8:03 am

Same issue here. The workaround that i apply is set the power to dynamic.

There is a clear interference between the Elrs module and the gimbals.

Max Damage 28th April 2022 - 8:23 am

Thanks. But it’s sad that there is no comparison of sizes with Tango 2 and TX16s.

Graham 21st February 2022 - 12:31 am

Is there any chance you would know why on my New Jumper t pro 1000mw internal unit. It says battery low , showing 6.4 volts on the screen and wants to power off. But when i test each battery with a volt metre, they are each 4.3 volts
Appreciate your help Batteries are Brand New 4000mah When in the unit took over 1 day to charge

Vitalii 10th February 2022 - 5:06 pm

Great reviews! Thanks! Have you been able configure sliders/pots? Mine acts like a button on the edge position. Have no idea, might be its an edge tx bug or i’m messed something?

OLIVER 28th February 2022 - 7:32 pm

i have the same problem but i don’t now how to resolve

Peter 30th May 2023 - 10:40 am

Bei Geräteeinstellungen unter Kalibrierungen (Sticks, Schalter) kommt weiter unten die Spannungseinstellung. Am besten die Akkus extern voll laden wenn möglich, dann einlegen und jetzt unter besagten Einstellungen 8,4 V eingeben. (Nicht bei RTC, das ist die interne Batterie für die Uhr)

Mervin 8th February 2022 - 8:47 am


Are jumper products good ?
I am confused between the Radiomaster TX12 and the Jumper T PRO

Scott 27th January 2022 - 11:51 pm

Can you provide any information on the ELRS module that comes with this radio? What version, ELRS 1.x or ELRS 2.x. What target do I build to update the ELRS module?

bill 29th January 2022 - 4:08 pm

I’m struggling to flash the internal module.

It looks to be a DIY_2400_TX_DUPLETX.

I’m not finding any information about it, and my first flash failed. The controller didn’t come with any documentation about the internal elrs module.

Kou Inoue 24th January 2022 - 12:12 am

The flight mode buttons can be used independently by ungrouping them in the model screen.

Ben 21st January 2022 - 5:07 pm

Banggood is already offering a version with built-in ELRS. (if you select T-pro -> D version)

Karel 21st January 2022 - 12:12 pm

Does the external module only support crossfire? Or can e.g. a slim frsky/multi module be added?
In case you get the internal Elrs

Dave 21st January 2022 - 4:48 am

Hey Oscar, can you update best product articles like the best fc and esc as you last changed it on 2020.


Alfindo 26th January 2022 - 7:23 am

Hey Oscar, could you please give us an update on the best product articles like the best FC and ESC as you last changed it in 2020. thaks

Jonas 22nd February 2022 - 5:54 pm

Mine turns on automatically when i plug the usb charger in.
Green Led on the back is on but it seems that it took forever to charge.
Why is it turning on when i plug usb in?

Kevin Getchelol 30th May 2022 - 2:10 pm

I bought the 1 watt internal system from jumper. Being a new pilot I find it extremely hard to download the appropriate LUA script onto the radio. Six weeks and still have not had this piece of s#$t up and running. Manufacturer flaws FOR SURE
