Great review Albert. I was really hoping it would work 😢

[@carlocolombari7371]

Thanks Albert, so the suggested setting is 250mW MAX with dynamic power ON? Whay the external modle don't switch off with internal module ON?

[@AlbertKimTV]

When I tested 1W, it fried a transistor on the main PCB that switches the power on/off to the external module bay. On a normal T-Lite it will turn off. Mine is broken due to this testing.

[@ramo_fpv]

Hi, same module but I'm using the x-lite. It works with no problem on 25-500mW. (dyn power off) But when I use 1W , it failsafe instantly. I cannot liftoff. Same problem with power?

[@AlbertKimTV]

Most likely. Keep in mind that if you use the full sized module, it requires external power on 1W and up as well. So they must know internal radio power isn't enough for 1W under most circumstances.

[@proprotornut5389]

Great in-depth review. Thanks.👍

[@jeffsDad]

Do you think the module, at 250mw, is enough of an improvement over FRSKY R-XSR or XM+ to justify the cost? I really like the form factor on my T-Lite--and it's not like you can buy a Tango 2 anywhere right now anyway.

[@AlbertKimTV]

Even at 100mW, it has way more range.

[@rjsvids]

[@shadowofchaos8932]

Interesting. I bet version 2 has a better voltage regulator. Under powered and overdrawn on power. Should it be a 2 cell receiver for increased reliability? Fly far enough and the receiver could dropout.

[@ShermanKenB]

Thanks for this info. Just starting into the hobby and have purchased this radio. Was originally thinking about picking up a drone with a FRSKY XSXR receiver. Seems like cross fire has better reception which seems like that would be a bonus. My question is how far of range would I get with 250mw?

[@AlbertKimTV]

Range depends on your RF environment. In an urban environment with lots of RF noise, range is less than out in the open rural areas with less noise. On 250mW, you can probably go 10km under ideal conditions. Way more than you need.

[@curlymaplebandit3107]

Love the T-lite in my hands, just comfortable. Am guessing with the flying I do the 250mw will do fine. Did order a couple of those moli 18650s. We’ll see how they stack up to the Sonys i used to use vaping.

[@johnk8825]

Albert I think you went above and beyond to make this work in all configurations. Jumper just failed to realize (or admit) that dynamic has changing power levels.

[@HaveFaithInGod]

Can the crfr module be powered with a separate source? That would be a simple solution I'd think. Just a "juice box" in my pocket or velcro to the tx case.

[@AlbertKimTV]

Some people have had success with the USB-C port on the nano-TX module but the power source needs to be powerful enough to provide enough current. Without proper current, it still won't work.

[@HaveFaithInGod]

Did you ever figure out why your nano module doesn’t turn off when using the internal module? I have the t-pro and have the same issue with the external nano module not turning off when using the internal module. In fact the external module stays powered on even when the tpro is turned off!

[@AlbertKimTV]

There's a regulator IC on the board that got fried. So even after I modded the power in the later videos it still stays powered on.

[@valden]

I appreciate you doing these videos. I went from not really sure if I should consider this, to almost pulling the trigger to resplace my x9 lite lol.

Have a jumper t lite and crossfire nano. Have set up external module to crossfire. In the tools menu I don't see as Crossfire menu option where I can set the power. Do I need to update the opentx firmware?

You need the LUA script and SD card contents

[@monkeymang13]

I'd be interested to see if the nano could be powered externally as well. I probably won't use it over 250 mw either, but it'd be nice to know if I could do it without needing to solder or otherwise modify the radio.

Your voltage cut offs are true for the Lipo batteries, Li-on can often be discharged further, even down to 2.5 but usually 2.8v at least.

[@FLMan180]

Could we just power the module with a separate Lipo like a 2s or something and solve all the issues? It would be a lil bulky or throw it in your pocket .

[@seewell8168]

After switching the springs out on the Tango 2 did you also loosen the tension? You can set them very very loose, almost no tension, if you like them that way.

[@AlbertKimTV]

Wait, where is that? I swapped the springs to the looser one but didn't see a way to make them looser... is it just the screw on top? I also prefer the distance between the sticks on the T-Lite over the Tango 2. Is there a way to move them closer together?

[@whiffles]

Great video! So basically no more than 250mw and you must use a good cell.

Can I put some external power to the nano tx module through type c connector? 2s lipo or something like that? thank you!

According to the specs, the input voltage is 6 to 13v so a 2S lipo should work in theory. I have not tested this however.

[@f2bcnc74]

at 16:46, did you check that the External module is OFF in your system parameters in order to use only the 4in1 inside module only ?

[@AlbertKimTV]

Yes, it is off. When you setup the model to turn on the internal module, the external module is set to off by default. I don't think there is a way to have them both on at the same time in OpenTX.

[@f2bcnc74]

@@AlbertKimTV strange : on mine the external module is off when I use the internal module. I really like these little radio, have also the Tango 2 but prefer the feehling and the size of the T-Lite. 250mW is way too efficient for our little quad even inside buildings, don't you think The only bad thing : the "on" green light is too agressive .. Regarding the Tango2, no trim so I can't use it for my little sailplane (Lidl glider or foamies ie)

[@monkeymang13]

What external battery pack do you recommend? The one I have doesn’t seem to work once the radio is turned on.

[@AlbertKimTV]

How are you connecting it up? I think it will need to be one that can handle a high current draw. I haven't tried any power banks myself. I only know of one guy who used a lipo and BEC with current output up to 25A and that seemed to work but I have not tested that scenario myself.

[@monkeymang13]

It’s usb from the battery to the usb-c port on the nano. The power bank I have I guess auto switches depending on device. Maybe that’s why it doesn’t work.

I estimate at 250mW full power I can get roughly 5-6 hours power on time depending on how far away I fly and general interference from surrounding objects. If you just leave it on without it transmitting to a receiver at distance, it can stay on for a lot longer but that's kinda pointless.

Pretty interesting, Albert! Thanks a lot! 😃 Well... I tried to make many different things work with only one 18650 cell and dc converters (step ups) and never had much success. Unless it was something that pulled really low current, because then it works. I bought many different dc converters to try, but... It was always the same. Sometimes I had to modify the project, taking the battery off and replacing by a dc input... Or just took the converter off, when it was possible (like the last speaker box I made). You know? So... I really don't trust dc converters, unless they're step downs... Then they work as they should. Anyway... It's a bummer. If they put space for 2 or 3 cells it would be totally different.

I’ve seen several reviews on the power issue. Kinda a bummer but the nano can be powered externally on the USB port. A pocket sized USB power brick can be used from what I understand. Get a USB cord long enough to comfortably reach a shirt or a pant pocket could be a good solution. The power bricks are fairly cheap as well as the cords but it is another part you’d have to buy but still ends up cheaper than the tango 2. Just a suggestion.

[@JimB40]

Testing in this environment with dynamic power on, does say nothing. You can set whatever (like 1W) and transmitter will output 25mW (lowest power) in such proximity and draw low current. Check TPWR in telemetry to see what is actual TX power output. Jumper claims that they tested and “it works with 1W/dyn power”. Sure. They did the same thing :) When RX/quad is 1m away from TX cause real power outputted is 25mW. Then once you fly away and TX will try to go up with power above 250mW, current draw will be too high and TX will stop working as you tested. That means failsafe. So saying “it works with 500mW/1W with dynamic power” is asking for troubles. Cheers.

[@AlbertKimTV]

Are you just repeating what I showed or are you trying to mock me? Not sure... in any event I got this to work with 1W and dynamic power OFF... check it out.... kzbin.info/www/bejne/hpeXnGmHm5mVnsU

[@JimB40]

No intend to mock. It wasn't clear from your movie if malfunction at 500mW and 1W was due to excessive current draw or due to RX being to close to TX. Now when you bypassed BEC and it works, it shows it was due to excessive current draw. So without this mod, setting power above 250 mW is risky in both settings of 'Dyn power'. Just when set to 'On' one will find out about that once flying further away. And this is not obvious at first sight as when RX is close to TX it seems like it works okay for 500mW and 1W settings.

All I can state is my own personal experience. I already know a couple guys who tried my hardware modifications and apparently they messed it up somehow and smoked their T-Lite. Apparently they reversed the polarity somehow, somewhere, but they didn't know much about electronics so it didn't surprise me at all.

[@Neukom720]

Albert just a heads up when you changed it back to 250mw from 500mw you accidentally clicked it back to 500mw that's why you thought it didn't save and why it wasn't working then but yes the voltage boost regulator is being overwhelmed and the scary part about dynamic would be as you fly away from yourself and it increases power it would drop out and you would failsaif you loose your drone or something else very bad, they need to fix it with a better regulator or out a warning on the box that it can't do over 250mw which is fine for most people as long as people know

Thanks for the testing. This is such a huge turn off. I guess I’ll just go with radiomaster tx12. That can do 1w crossfire no issue right?

[@owenk5926]

Yup! Happy flying.

@@owenk5926 just to confirm. It’s micro tx crossfire on 1w right?

@@EnglishTurbines thanks for the info. Appreciate it. Guess I’ll just go with radiomaster instead of this over hyped and problem plague t lite. Usual stuff from jumper I guess.

[@joevo2]

@@EnglishTurbines I’m currently using tango 2. I just wish there’s an adapter for full size jr to lite jr. Just a personal nitpick so I can share module between my tango 2 and maybe the tx12. Otherwise it’s fine I don’t really mind the gamepad style especially that tx12 is pretty small to begin with

I haven't tested that radio and the nano module doesn't work with that radio anyways.

Yes it can

Can you make a video for the mod

[@AlbertKimTV]

If there are more people interested... I'm not that interested myself because 250mW is enough for me and if I want more I can just plug in a lipo into the back of the module.

[@WIZARDDETECTIVE]

How are you plugging a lipo in the back of the crossfire nano module? Is there an adapter?

[@AlbertKimTV]

@@WIZARDDETECTIVE I have a fix that just uses the internal 18650 and no USB port needed... I need time to make the video so please stay tuned!

love this update. you and gal are the ones that's giving great infos for this lovely radio (which I will soon get) the regulator upgrade seems to be the best mod option.

[@mexahuk2990]

how far can you fly with it without crossfire ?

[@AlbertKimTV]

The normal 2.4ghz protocols vary in range but the most is about 1.5km max distance.

[@mcyhanick]

Jumper put on a note on their aliexpress page that you need an external power supply connected to go higher than 500mW.

[@AlbertKimTV]

They have a design flaw that can be fixed for 1W support on the internal battery. See my other video on this topic... kzbin.info/www/bejne/p3uTiWuAadt0ack

[@anthonyechevarria5485]

I’d love to use my crossfire nano with my jumper t-lite but it seems like it’s not quite there yet. I’ve been using this radio a lot more than my radiomaster for my frsky receivers this past week just because it’s easier to carry around and the gimbals are a bit better then the LiteRadioSE gimbals.

[@AlbertKimTV]

It works fine up to 250mW of power which will give most people enough range to out run their video anyway. I have never used crossfire over 250mW so this limitation doesn't harm me in any way.

[@43Apfel]

According to TBS the full size crossfire is consuming 3.2Watt at 2000mW transmitting power. With a fully charged cell this should be no more than 1Amp at the battery terminal! Assuming that the radio will draw no more than 0.5Amp pretty much every old 18650 should be able to handle this sort of Current! I assume maybe the battery is making very poor contact in the battery bay, which could lead to a massive voltage drop. Have you tried bending the contacts even more to guarantee a really tight fit? Once I receive my tlite I will do some testing myself and confirm the Theorie. As always, great video!

[@AlbertKimTV]

It's not the contacts as I have already bent them to make the best contact as I mentioned in the first video. The problem is in the way the power is routed inside the radio. It's a flaw in the design. Well, I talk about it at length in the video so not gonna rehash it here.

[@43Apfel]

I watched all the tlite videos and surely I have seen that you bend the contacts 👍 I still suggested from the radios behaviour that there is some contact point or internal trace with high resistance leading to a huge voltage drop.. once my tlite arrives I will do some measurements and maybe switch voltage regulators around. If I find a solution I will make a video on it :)

If the switchs can bust off I think the whole concept of that type of controller is just a big waste

[@AlbertKimTV]

That's just about every controller in existence in FPV. However, because this radio is small and light, the switches are harder to break off than larger and heavier radios.
