Thanks to this video I am up in the air having a blast!!! Definitely a transition from the pocket. I like both. This one feels and looks more serious, appropriate for a gig or AMA field. Whereas, pocket removable sticks are SO NICE, fits in your pocket, and is ready to bind to the Hummingbird V3... once you choose a packet rate or some frequency thing, you're all set up ready to go. I flashed via WiFi. Took a few attempts... they say you're crazy if you keep trying the same thing expecting a different result, but in this case it takes some of that
Finally, a comprehensive how to for this controller. Thanks D.A👊👍👍
No problem 👍
As a total beginner I am super grateful for this super detailed video. Now I understand why my extra buttons don't work when I am trying to learn to fly in a sim, they have to be set to a channel! 👍🏻
Glad it helped!
Many thanks for you video!!!
I have updated my Jumper T20 with this video.
Glad it helped
You rock brother. Thanks as I just ordered mine as my openTX TX16s max just wigged out on me with my external elrs module. I have the T lite v2 w/ edgeTX but love the feel of the full size. Seems just as simple as setting up my T lite for my racing whoops with spi rx's. EdgeTX is the way to go!!!! Love the content!!!!
Glad I could help and thanks for the positive feedback!
thank you for the guide!
No problem!
GREAT INFO SIR I WILL GOT 1👍👍👍
I just bought T20s radio. I have question with 6 funtion buttons next to each other. How to make 6 buttons work independently? Now i just turned ON only one of them
I can't get my jumper t20 3 position switch to get the full range in inav mode i only get the first 2 positions
im struggling with manual device selection,its not picking up my transmitter do you have a vid on what to do in that case pal?
The same happens to me, did you found the solution?
I don’t recall having to go through the entire ExpresssLRS process with my pocket. Isn’t it already set up with 3.0 or more version of ELRS?
How do I set up these six buttons to one channel? I couldn't find any info about it
Just purchased one and it on the way. I’m new to open TX and ELRS radios. I always buy drones with DJI PNP version. Do I have to setup my radio (per your RUclips video) before I can use and bind it to the receiver. Or the radio comes preprogrammed.
Just order drone with ELRS receiver pre install.
You have to follow this video when you get your radio controller. You also need to setup your receiver
Thanks for the in depth video .. does this radio works and bind any crossfire receivers ? I heard you mentioned it several times in the video . Fully Subscribed .. thanks again
It will work with crossfire if you get a crossfire module to plug in the back in the external module bay
I was following your video on flashing the Jumper T20 and got to the part where you plug it into the computer and choose serial port from the 3 options onnthe screen of the radio. When I do this I only get the option of comm4 on the computer. I went and downloaded the cp210x drivers...after downloading them I still only get the comm4 option...what am I doing wrong. Thanks in advance and love your channel!
did you sort this problem because im having the same issue?
Thank you for your quick getting started guide!
Some remarks:
0:18 : it says "processor" on the screen - that is completely wrong, it refers to the RF frequency, not the processor speed.
2:10 : The baudrate for CRSF is still at 400k, for reduced latency 1.87M works just fine and has no stability issues.
Good pickup at 0:18, that was my editor and I didn’t catch it.
People can’t actually tell the difference between the baud rates so for latency so it’s not worth changing.
hello darren. in my internal rf i only get 500hz and i cant change it....but if i change the reciver option to "1" (or another number) it changes for 250hz...what means that reaciver option (2.14 on the video) thanks!
The frequency number refers to the packet rate. If u want to change the output power, hold down the menu button and go into the LUA script
One question u plugged the drone telemetry recoverd but how mine rx blinks twice after a while green light flashes than its solid grenn but nothing happens in betaflight
Assuming you have ELRS; Have you bound or flashed your receiver?
Companion as the edgetx of the jumper t20s 2.4Ghz is updated
my t20 does not connect in dfu mode, what could be the problem? the power button lights up as it should. lower only 4
What do you mean DFU mode at no point did I say go into DFU mode
Can you make a video for fpv simulator setup with this controller
is it even possible I am thinking about getting this but have not found a setup guide for it and don't want to find out it doesn't work...
@@WestpalmFreerunner I have a 2019 MacBook Pro so I have to use a usb adapter. I’ve tried several simulators and they can’t detect the controller. I should’ve bought the tx16s.
@@burnaxel thanks for the reply, I have a MacBook Pro as well.
@@WestpalmFreerunner I’m not sure if it would work on other computers or laptops with usb port
👍👍👍👍👍👍👍👍👍👍
What is trainer mode? Do you need to turn that on for for simulators?
Trainer mode allows you to connect two Radios together when learning to fly.
It allows the “Master” radio to take over the controls of the aircraft when the “slave” or student radios screws up.
Like a dual steering wheel for learning to drive.
For the sim, create a new model with Internal RF and External RF set to off, then connect via USB
@@DarrenAllatt thanks for the quick response
Огромное Вам спасибо🤝
With which receivers this radio is compatible? I couldn't find anything on the manufacturer's website.
Any ExpressLRS receiver.. if you buy the ExpressLRS 2.4 version, just get any ExpressLRS 2.4 receiver
@@DarrenAllatt Thank you!
Does it support elrs backpack?
Not to my knowledge
hi darren my configurator won't see my radio even if I downloaded the cp210x drivers, any help?
Have you plugged it in and selected USB VCP on the menu?
I did it with the wifi option at the end 😁👍🏼
in Device I have Jumper AION T-20 2.4GHz and V2 (Jumper AION T-20 2.4GHz V2 TX) how understand what choose?
What does it say on the box?
@DarrenAllatt when I connect with wifi to ExpressLRS TX, its writed Jumper AION T-20 2.4GHz TX
Firmware Rev. 3.3.1 (e051b8) ISM2G4.
and on box writed T20S ELRS 2.4 Item: C10085, dont see anywords with "V2"
@@strel9 where is this v2 you are referring to?
Thanks for this guide.
I'm running windows 11 and updated the the CP210x Windows drivers from the Silicon Labs in BetaFlight, then re-booted for good measure.
The manual serial device selection in ExpressLRS Configurator only show COM3 Microsoft and there is an orange triangle on Jumper T20 and USB Serial Device (COM3) in Windows Device Manager. Does anyone have a fix for this?
You have to right click and manually select the CP210x driver for the Jumper T20 in Device manager
Would you happen to know the link where I can download that driver?
I've downloaded and extracted both the CP210x_Universal_Windows_Driver and the CP210x_Windows_Drivers, and run the CP210xVCPInstaller_x64.exe program, but device manager still says Windows was "unable to install your Jumper T20 Serial Port" when I try to update the driver. Any advice is appreciated.
@@DarrenAllatt
@@RedondoDennis got the same problem. did you fix it?
I am stuck. you say go get cp210x thats all. I followed The silicon labs page but I am a total beginner. Could you please explai. How to get the cp210and the how to get the edge TX in that box on the config instead of just Com ports. I cannot figure it out thank you sosososos much!!!
Hey, you need to download and install the drivers - If you want to book a time for 1:1 Troubleshooting, you can at this link tidycal.com/darren.allatt/fpv-coaching
Hey. Thank you for the response. I tried to download off the page but just kept bringing me to other pages and other pages. I also pressed the link that you sent me for 1 on 1 and it says page disabled. I am ready for the 1 on 1. I will be your best customer I suck w computers!!! Lol. Let me know when your ready!!!
Sorry I forgot to enable the booking link it’s now been turned on you should be able to use it
Hello iam having a problem . I have a brand new Jumper t20s and a foxeer 2.4ghz lna reciever. I have follow the expresslrs guise for setting everething up. But at the bench test 25mw at 1 meter i get -100db on rssi1 TX. And i also get a critical alerta of low rx signal. If i move the radio like 0.5meters away it Will failsafe...any nidea about this?
What’s your antenna configuration?
@@DarrenAllatt where i check that?
@@gonzafpv2843 you look at your atennas and see if they are the same direction, ie both horizontal or both vertical etc
@@DarrenAllatt both are horizontal
@@gonzafpv2843 you probably have them too close, go to a park where you can walk and pick it up if it failsafes to test. It shouldn't but this would just to be sure.
No matter what I do I cannot get the ELRS script to load. It was working at one point.
Changing firmwares, baudrates and things, no luck.
What is internal RF set to?
I'm have same problem
@@DarrenAllatt HARDWARE> Crsf 400k. SETUP> Internal RF CRSF External OFF...
The Lua Script is loading forever, I've already tried to do the main forum and community repairs like creating new models, going to the Hardware page to add and change frequencies...
@@TercioTelesdo you have the ExpressLRS version or the 4in1?
@@TercioTeles I had to return my to the FPV store that I bought them from and they tried to see if they could fix it over a few days.
They could not so I got a full refund.
My T20 Pro has got AION T- PRO v 2.5.1 from the factory.Can only update to 2.5.2 under "Jumper" & "T-Pro"
Tried doing your method with the target " Jumper 2.4Ghz &....T20"...3.3.0 .but configurator 1.6.0 will NOT Build it under "Wifi" method to my p.c.🤔
Tried EdgeTX Passthrough method as you did,but the blue updating bar jams,after pressing "build"......so fails.
Seems I,m stuck as a T-Pro on 2.5.2🤗🤣... even tho I copied your video precisely,...not sure now how to update to correct target and 3.3.0
You need to download the latest configurator. Sounds like you are running an old version
@@DarrenAllatt Many thanks Darren I'll make sure I'm using 1.6.0👍
