Does Jumper have an excessively high defect rate? I noticed that some stores do not carry the Jumper and asked them why. Off the record, one store told me they had too many returns from previous Jumper radios. This is just anecdotal, and it's off the record, so I didn't think it was fair to include it in the video, but I did think it was information that you should know before you make a buying decision.

I'm using the Jumper T18 Pro and T-Pro v2. Haven't had any Problems with them but early production T18s had issues with the SD-Slot as far as i know. Otherwise their documentation isn't as good as Radiomaster. A lot more digging through forums and github. The T-Pro v2 for example is not compatible with the T-pro v1 firmware and after a failed flash i wasnt able to find the original firmware for v2 on their website. But overall im very happy with both radios.

No complaints about Jumper quality from me, I have a Jumper T-Lite V2 ELRS, using it every day without any issues ever since I bought it last year. I wouldn't hesitate to buy the T20 with the Hall gimbals but I just don't need yet another radio, I got three already (TX16S JB Edition, TX12 Mark2, Jumper T-Lite V2)!

About the charging circuit: USB-C chargers actually don't apply ANY voltage if the USB-C port on the client is not implemented properly. I noticed that some FCs don't work with C-C cables, but they work with A-C. That's the same thing. It literally only takes two resistors on the PCB (from the CC lines to ground), to enable 5V output from USB-C chargers. Sad thing that some FC manufacturers and Jumper just don't care about compliant USB implementation

Ok, I've been looking into FPV for about 2 weeks now, and I believe a big Thank You is overdue at this point. I'm doing lots of research trying to make sure I make educated purchases, and your videos have been invaluable. This radio (or rather the V2 version) seems like it's made for me, and will probably make me happy for a long time - both in the sim now, and with real drones later.

Just when I thought the Radiomaster Boxer was the king this one comes along... got to say it has an odd but very appealing look to it, I really like the large heatsink on the back of the radio, the 21700 batteries are great, the folding antenna, the full size gimbals, etc. About year and a half back I really wanted a TX16s Max with the color screen but did not have the funds so I ended up buying a TBS Mambo - which I have been very happy with. No problems to speak of, I have just about every single protocol you can get with built in tango and modules for ELRS, etc... I bought the radio because I did think that this form factor was ideal, the price was 1/2 of the TX16, and they did promise to add EDGE or OPEN TX to it - they still have not done so which bugs me quite a bit - almost enough to dump the radio and pick something else up and with this Jumper there are now many great contenders. I bought the TBS radio also because of the quality of performance that I believed they had in their products which i do think is true, they make class leading stuff but hey guys, there is now a lot of competition for the Mambo. I guess I would ask about Tracer, it really does have some great specs so I am not sure why it does not find much support. I finally broke down and bought a receiver and installed it and it flies just fine. I know Bardwell did talk about tracer on this radio and questioned why they chose tracer, perhaps I will go revisit that video. Cheers

On my Boxer, I re-purposed my Yaw and Throttle to be momentaries, two on Yaw on one channel, the two on Throttle on another. I use one of the Yaw trim's (trim-pressed-right) as my Pre-Arm. I really like this configuration. I currently probably under-utilize the one momentary as a "Timer Reset" button.

I was so excited about this radio until I saw from multiple reviews how they built it so cheaply. I really wanted to love this radio because it's everything I wanted in a radio but the inside of it is just kind of gross to me lol. Oh well, I'll settle flr the boxer....it's not the exact form factor or looks I like but it is super comfortable and well built. Not to mention cheaper in price. Boxer it is!

@BluestarP3D 5 ай бұрын

Start this off by saying that your channel has been my goto for learning and studying about the different systems and peripherals for this hobby. It has been immensely helpful given how in-depth you usually go, and you can see this with your passion in the hobby. It's been great as a soon to be drone flyer. I like to research the hell out of something prior to purchase, juggling between specs and compromise. You've been always helpful. With that said. I really looked forward to your input on this controller. However, I felt a mostly large bias for Radiomaster. The lack of mentioning the 1mw output, is what caught me off guard as it was stated several times in the Boxer review. Paired with tons of enthusiasm and emphasis on how great that is for that form factor and price point. The disagreement over 21700 batteries was big as well. Luckily for me, since I worked in the vape industry for several years, I have tons of 18650s and 21700 batteries and chargers, that I just skipped over that. Something I don't normally do in your videos. The biggest turn off for me with every Radiomaster controller is none of them esthetically look pleasing to the eye. Which matters nothing in hindsight... But is just, "one of those things" that will attract me to something in the first place. Your description of the gimbals was a bit off as well, as I'm used to every other Radiomaster review showing how "accurate" they are. In-fact, everyone else mentions how nice the Futaba like gimbals are, on the Jumper T20. So it leaves me confused. To say I'm now conflicted on what controller to get, is an understatement.

Unfair I guess, but I have an old Jumper T16, and it was a nightmare because the ribbon cables were unreliable. They even seemed to shake loose when the haptic was used. When flying you really want to have confidence in the reliability of the design and manufacture. I switched to radiomaster and cant see any reason to switch back to Jumper. Also, no momentary switches is an "own goal" by Jumper. Colour touch screens are hype and not necessary, but this tiny effort about the size of a wristwatch is not viable for my use.

@HrDux 6 ай бұрын

@@AT98AT If there's enough room, it probably is possible. I never did it on the Boxer. If you're going to try putting a Crossfire module inside your radio, make sure that you shield the electronics with copper foil. And make sure the copper foil is insulated so that it doesn't short anything. The Crossfire module puts out a TON of RF and it will interfere with your controller's battery voltage sensor, the trainer port, speaker, and the gimbals. Especially at 500mw and 1w modes.

I have full size screen radios with edge tx and open tx and really you can do everything just as fast, especially if you already know the menu's and menu structure from already having an opentx radio. Its an interesting design, but i think id really like to hold it and try it before i bought it which would be a problem. I love the Boxer and also like the Jumper T. I want to change over to ELRS so im looking for a 1W internal ELRS module or ill get something thats 4-in-1 and use an external module for the ELRS, but im really trying to keep the weight and complexity down if possible..

Build quality is piss poor, especially with those red switches, there is absolutely no excuse, they could use tiny PCB worth 5c, solder the switch first to it, and then have some nice big pads for the wires with some hole for the wire to go thru for strain relief. Charger incompatibility is caused by them just having wrong wiring of the USB-C plug, missing a resistor or something, tho ideally they should have some handshake IC that will work with everything and negotiate nice juicy 2A, such IC is very cheap like 30c. If you send me high res pic of the area around the USB-C connector I can verify if it's indeed missing the CC line resistor(s). At 0.8A and 2S 5Ah cells it will take like 15 hours to charge, painful. I currently use jumper t-pro and it also has very slow charge time and also USB-C incorrectly configured was thinking to re-design the PCB but I can't justify the effort for just one off PCB.

While it appears massive (which is good to sink heat) there is no fan but really what got me is ... does it make sense that the external modules bolt onto the heatsink? I guess my question is does it really even matter? Will the external module block cooling to the heatsink causing the ELRS wattage output to drop down due to heat or could it heat up the external modules in a way that mucks them up... probably not, just a nitpick i guess but has anyone else had this thought?

Just got new Jumper T20, works well with drone, but my Mac can't see it at all. SD, Joistick (clasic/advanced), no reaction, or no 'device inputted' sound. I've tried diferrent USBs from the package including. Have anyone had a similar issue Mac (m2) -> Jumper T20 Joistick connections issue?

Are you using a USB-C-to-C cable? Sometimes that makes problems. Try an A-to-C or a USB hub with USB-A on it.

I had to resolder a broken gimbal wire twice on my T-Lite V2.

Btw. thiner wires can transmit signals faster than thick wires. But not sure how much it matters on hall sensors / potenziometers.

@userIDONTKNOW 10 ай бұрын

@@pongmaster123The thickness of a wire changes the impedance, capacitance and so on. For signals you want a low capacitance, because of that you pick a thin wire for high frequencies on pcb design. Im not gonne claim to know everything, even after me designing pcbs back than. But as i said, not sure if it matters on a gimbal sensor, even if it is pulled with 1khz. And maybe the term "thin wires CAN" wasnt the best choise. Its more like, can you let high frequency signals threw it without any negative effect of noise.

review jumper t14

@cshaw317 10 ай бұрын

Hall sensors are superior to pots regardless of what Jumper think. It’s a basic upgrade pro gamers do to their controllers as it can reduce the dead zone of the stick without having stick shift which is caused by the pot sticking slightly of centre. Hall sensors have no physical connection other than the bearing, this means no resistance and no wear and tear. I see it as how the optical mouse is an upgrade to the roller ball mouse if anyone remembers those! 🤮

Can you please make a video on how to update the firmware please

@JoshuaBardwell 10 ай бұрын

The radio ships with the latest release of EdgeTX on it. Right now, there is no way to update the firmware until EdgeTX 2.1.0 comes out. When it does, this will be how you update it: kzfaq.info/get/bejne/gpOaktB7zc-uoGw.html&ab_channel=JoshuaBardwell

So bout the t20s Express lrs 2.4 can't bind it to my drones and they're running 3.2.0 plz help

@JoshuaBardwell 10 ай бұрын

Ok so you need to update the ELRS firmware not the EdgeTX firmware. Use this tutorial: kzfaq.info/get/bejne/g6x2iNZ_nsCsg4k.html&ab_channel=JoshuaBardwell

My expensive Futaba 10px surface radio and even my tx16s (top usb port) dont work with USB-C to USB-C. There is a lot of info about this around the internet for many devices. Lazy USB-C implementation.

Sadly AGO1 cnc gimbals don't fit (at least without some heavy-duty dremal action and some internal electronics re-arrangement). KababFPV just ground down the gimbals in this video with a Dremel to get more throw. If someone does figure out how to get AG01s to fit, I have a brand new pair of AGO1s in the draw, all rewired to fit jumper plugs, ... perhaps a 3d printed shim is needed.... I'm keen to get them to work!

Best looking radio out there. Too bad its made by a subpar company and the launch was such a mess. T-20, T-20S, selling hall sensor gimbals that nobody has even seen yet.

@brianfreland9065 10 ай бұрын

This radio would be just fine if it were 100 pr less...but frankly, asking for over 100 when the inside of the radio looks like a child assembled it is just upsetting. Almost feel like they're trying to get iver on my by doing so well on the outside and thrn hiding all that crap inside haha

Yes ! It seems that Joshua doesn't know that he has a T20S, because he said at 30:16 that the RDR90 are useless, while he doesn't test the hall effect gimbals.

Just got mine and the quality feels awful. And once I open the back cover it's an absolute shit show. Loose gimbal even when screws are adjusted to the max. The leaf "spring" that provides resistance is made of a strip of tin can. You can bend it super easily. Wish I watched this video before purchasing.

so sad with a jumpers quality.. add more pro plastic, better gimbals, better wiring, and it could be a winner for all

I never understood why people wanted a huge screen on a radio. I use it to fly my radio with my goggles on. I don't know what you would need a huge screen for.

@Leif_YT 10 ай бұрын

I prefer a larger because I use the menus and telemetry sometimes. I guess it also depends if you're a person that does FPV only, or someone that also wants to try other stuff like Wings, Heli and so on.
