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.

@Knirwes 9 месяцев назад

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)!

@NightimeBurnout 9 месяцев назад

can confirm jumper offers zero support with an insanely high defect rate. we have C R A T E S of dead jumpers that they refuse to deal with. dropped them entirely because of it. your quality control section of this video perfectly showcases why you cant trust these things. built like garbage.

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

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.

Interesting radio with some cool features. I really like the six customizable switches and really REALLY wish that RadioMaster would use this on their radios. Sadly, there is one fatal flaw with this radio - JUMPER. They have had enough quality issues that I will not touch their radios.

@giltroxx 4 месяца назад

Amazing video as usual, whats the better option for this 2024? jumper t20 or radiomaster boxer?

@genjitsu7448 9 месяцев назад

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

@dakzer55 8 месяцев назад

Thanks for the review, worth the punt to try supposedly higher resolution of full sized gimbals. As I currently use Frsky X lite with small gimbals. Hope it makes a difference. I didn't want to make the expensive jump to Radiomaster Boxer as nice as it is.

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!

@TiagoTiagoT 9 месяцев назад

Is anyone making radios sorta like in the Steam Deck form factor, with the screen doubling as FPV display with built-in analog receiver and ports to plug third-party video receivers?

@mxracingunlimitedltd7784 9 месяцев назад

I dont have a problem with my Tango 2 screen because the OLED makes it nice and clear. 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..

@BluestarP3D 4 месяца назад

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.

@wampelt 2 месяца назад

When i watched this video, i placed order :) İ just bought this radio. Normally i use t16 series. But its very big and heavy. İ have only 1 question. Can i use lua script as graphical telemetry widget with this 1.3inch screen? İ saw some guys using lua widget with 1.6inch screens.

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?

@Dan-ro6nj 9 месяцев назад

I actually prefer this smaller size screen, precisely because it's OLED and not LCD. Easier to read, nicer to look at, completely sufficient in size imo.

@tomverlaine728 9 месяцев назад

Giant screens on openTX has always been such a turn off, glad they stick to smaller now.

@saggyballsfpv 9 месяцев назад

10:02 of course we don't, influencers have bitched about momentary switches on the T-Pro and the single momentary on the Boxer that they've abandoned the idea.

@martr 9 месяцев назад

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 9 месяцев назад

The internal Crossfire mod is brilliant. I wanted to get a Boxer and hack a CF Nano TX in there. Too bad there's no SD card. I started logging telemetry data just in case and it helped me find where my quad fell in a mountain. The internal storage would fill up too quickly and you would have to remember to clear it out often.

@AT98AT 4 месяца назад

@HrDux Is it possible to install a crossfire in a radiomaster boxer?

@HrDux 4 месяца назад

@@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.

@AT98AT 4 месяца назад

@HrDux I just ordered a Boxer, I'm going to try to install crossfire inside, unfortunately I didn't find anyone on the internet who did it on a Boxer, I don't know if I'll succeed because it seems like a big operation to me, but thanks for the advice, nice of you!

I had an opportunity to play with this radio. For me it's too big, I much prefer my Tango 2 with smaller gimbals. I just feel that I can't use full range of gimbals when they are so big. I don't know why because my previous radio was Jumper T16 which also have full size gimbals. But somehow T20 feels bigger. But yea T20 is really nice.

@dakzer55 8 месяцев назад

Shame Jumper get a bad wrap for building bad quality control radios. But to be honest, after getting a Jumper T20 replacement clear case, it felt so solid that as long as you check over the internals of the radio when replacing the case, it is a good value way to try full sized gimbals if you feel the larger radiomaster boxer/t16 are too much of a pro upgrade.

@genjitsu7448 7 месяцев назад

So I really like this radio... except the ELRS heatsink on the back got me thinking. 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?

Its weird. Jumper needs to focus less on features and more on quality. T-16 had ribbon cable issues, t-lite had charger issues.

@Arek_R. 7 месяцев назад

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.

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! 🤮

wow, i think ill get the t20s over the t pro

@brianfreland9065 8 месяцев назад

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

@bulufish8208 9 месяцев назад

I'm staying away from Jumper. Way to many bad radios when I started fpv. Customer service is nonexistent PERIOD.

That thing is hideous 😂

@aasenov 9 месяцев назад

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.

@ali3n24 8 месяцев назад

Wrong video name! It's JUMPER T20S with RDC90 Gimbal

@LeeeeeRooooy 5 месяцев назад

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.

Why there is written “FPV sucks” ???

@yoyomin 8 месяцев назад

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.

@cyberneticinterfacemodular3996 8 месяцев назад

A few faults in it otherwise very good.

@RcReviewsLt 9 месяцев назад

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

@OmegaNineProfile 9 месяцев назад

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 9 месяцев назад

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.

@skelethornbro 9 месяцев назад

Yaapu or Inav Lua telemetry.

@icebrain 9 месяцев назад

I will never buy jumper again , piece off crap . I Have to take out ta capacitor to make my control work again.

@onemanmob6756 8 месяцев назад

JB pls stop saying you are not a gimbal snob - there is (I guess) nothing really bad about being one. your excuse for using the fancy gimbals is a definition of snobism.

@JoshuaBardwell 8 месяцев назад

I disagree. A snob would act like theirs is the best and others are inferior. My message is, it doesn't matter. Get what makes you happy.

@L-udo Месяц назад

comparing oled vs lcd on a radio is pointless

@snosk8fpv140 9 месяцев назад

Seriously? Been a fan since the blue falcon days. And you've been a trusted resource in my fpv progression. Having said that... Wasted a whole lot of time after 'I'm not a gimble snob....' to hear the build quality sucked. Could have just been upfront. Also noticed for a 'not gimble snob' you didn't compare directly to the pocket. So...my quick on your observations... Kinda cool, it was free.... Have to do a video... They hid button switches under cute faces. The gimbals don't suck (see a trend in wasting people's time?). Oh, and for a portable they made the switches easy to snap off and the wiring is sub par. Did I miss anything? Dude you're a respected part of the community and many rely on your honesty. Weak sauce. Do better.

@JoshuaBardwell 9 месяцев назад

Do you know why I didn't tell you about the build quality until after I looked at the gimbals? Because I hadn't opened the radio yet. You found out as soon as I did. If you feel like my videos are wasting your time, don't watch them. No hard feelings. I take people's trust and the time they spend watching my videos very seriously.

@snosk8fpv140 9 месяцев назад

@@JoshuaBardwell Fair enough. Never said your vids were wasting my time (might have mentioned that above). Said I expect better. You set a high standard some time ago. When you set the bar that high don't be amazed when people call out a sub par one. Fair?

@JoshuaBardwell 9 месяцев назад

I don't think it's productive to argue with you about whether this video is sub-par. You think it's sub-par and there is a certain way you think it should have been strcutred to make better use of your time. That's your prerogative and I respect it. But you are asking me to agree with you on that, and I don't agree. I put a lot of effort into each video and constantly am thinking about the best way to present the information to make the best use of the viewer's time and attention. This video is no exception. The gist that I get from your comments is that you think this radio sucks and you wish I would have gotten to the message, "this radio sucks don't buy it," faster. But I don't think that message would have been fair to the viewer or the product, and would not have been consistent with my usual approach of, "Present the product in a way that each person can see the good and the bad, and decide for themselves whether they like the product."

@snosk8fpv140 9 месяцев назад

Um...not really but OK. Much respect for the wisdom you share. Carry on... 🤙
