Thanks for the video, I ordered 3 from that link, don't need them right now, but the price, size & output power was too good to ignore.

Bro this vtx is better than my 1.2W AKK ultimate mini

Just bought me 2 of them! Thanks Nick!

I would be interested in your findings.

@@NickBurnsFPV I will send you an email when I get them. A few weeks I'm assuming.

@@NickBurnsFPV oscarliang.com/eachine-nano-vtx/

@@NickBurnsFPV Might be a little more than a few weeks, just got an out of stock notification...sooooo.... hopefully they ship in 2 weeks.

@@housinit I have gotten a few responses with others that have bought them. Overall I think pretty positive. I did have one report that it burned out, but I have no idea how it was mounted, and it was on a 40min flight, so I am thinking it was on a wing or plane, and possibly little air flow. I did also have a report that 400mw started out at 400mw but as it heated up came down to about 320mw, that testing was on a bench with a fan.

I sure hope long term these are just as good as the 02 and 03.

still waiting for my next 4. I suspect supplies are rare.

Very interesting! Is the current draw increased in these 900mW conditions or is it pissing away energy as heat on 250mW channels? Also it would be great if you could briefly mention what channels are 900mW. Thank you

Interesting results. Could you share more detail on which channels (frequenzies) were too strong / too weak? Or do you know if that will differ from unit to unit?

@@yekt3805 I'm not sure ... i assume it will vary unit to unit a bit. All vtx's have this variance (weak channels and strong) but this one varies a lot. Unfortunately, I wasn't really noting channels with strong and weak - sorry. It was just too hot to handle (most VTX's are they just have more area to hold) and I was too lazy to read the led singals indicating the channel :/

Thanks for you feedback. I appreciate you taking the time.

I could really only do it on the ground. I fly by myself :(

okcrc - You bring up an interesting point. The old Eachine VTX02 and VTX03 worked great when flying by oneself but would bleed horribly onto nearby channels making them tricky to fly with others.

correct no audio. I haven't tried that specific one, look similar the to runcam version. This could work like a backpack with a bit of foam tape, this is a fair bit smaller.

While that might be true, there is "science" aspects I didn't look at. Like channel bleedover when flying with more than 1 person. True mw rating is another, is 400mw really 400mw etc. Likely a number of others, this is plain and simple...fly it and see what happens.

This is what I'm wondering about also. A friend of mine has had some vtx's that had unbelievably good reception but he would blow every other pilot out regardless of frequency or output if he was flying.

yea, there are a number of "science" or other test that could be done, I am just not equipped for it. :(

@MAD GRUMPYMAN flown with 4 people in the air at once using tbs unifys. The moment someone powered a eachine vtx, I am not sure of the exact model, but it blew a couple of people's video straight out causing crashes pretty quickly. We don't run raceband either. We run the most spaced out possible AFAIK channel wise. R1, F2, F4 and R8.

Sure. Not being in the racing community these are the sort of details I am not aware of. Thank you

Thank you. I appreciate it.

They are VERY good for the price. I've been flying around my brick house with metal colourbond fences for years with vtx 03 on 25mW before Rapidfire and recently with Rapidfire (much better). I must admit though, my house is half the size of Nick's.

Thank you .

Thank you. I sure hope yours work as well as mine.

That's an older model. Still good but isn't it stuck at 25mw?

Thank you. Many are saying the sale is still on.

Nick Burns yes sir still $14.99 ... im going to grab a few before they raise price..I’m going to use your link in description...😉

surprising...for me at least. :)

@@NickBurnsFPV I wonder how well it would perform with my ev800's/stock antenna. They aren't so great, as I'm sure you're greatly aware of, but seeing how well they perform on your sharks, and especially on the DVR footage, I'm assuming they'll be much better than what I'm running on most micro builds!

It sure wouldn't be worse. And depends if we are comparing a 25mw to something like this up to 400mw.

@@NickBurnsFPV I have a few that go upward of 600mw, but they're too heavy for the micros i've got going on so far. I just know the stock antenna on these goggles is trash lol!

competition drives the market for us...for sure!

it should do you up.

That's always a concern but ... FWIW ... the VTX's from Eachine have been pretty good for a long time. Like the VTX03/02/03s, ATX03, etc... etc.. have all been reallllly solid for me.

@@CesiumSalami Mhhh I could write a list twice as long of VTXs from banggood with eachine label that failed me :P :P

@UCRjcmtotdeQgPoYK5Iz-HMg The new diamond vtx from happymodel is more interesting with 720P30 recording, 200MW. It has got a SD-slot

ah man, need to get out and fly that er349. Eachine doesn't have a habit to use mmcx. :(

I would expect it to get hotter the higher the mw. More power more heat, a vtx isn't 100% efficient especially without a proper tuned antenna. The more power you try to get it to pump out the more power gets "stuck" in the vtx and dissipated as heat.

@@thirtythreeeyes8624 these things a lot of the time draw the same power regardless of output. Depends on the electronic design

@@Kabab Really in my experience the higher the output power the higher the input power and every adjustable vtx I have or have seen goes up in both amp draw and heat when the output is turned up, which would make sense considering on 25mw the PA chip isn't even active and that's what's drawing most the power. It seems that at 25mw most will draw about 100ma -150ma with a good antenna, where as a 200mw or higher will draw from double to triple and it goes higher when you go up in mw, you wouldn't expect a 2watt vtx to pull the same amps and produce the same heat as 25mw right?

@@thirtythreeeyes8624 not all vtxs work the same. Many will default at 600 and just knock down to 25mw without actually reducing amp load

@@Kabab That's a really shitty design then. I wasn't even aware you could have the pa on and acting as a pass through at the same time. If that's true and they take the same power at any setting than they should be getting hotter the lower mw that's just basic thermodynamics. less power out same power in means heat and lots of it especially if it's the same amp draw as a 600mw vtx and only transmitting 25mw. I'm interested to know which vtx are you aware of that does this so I know to never buy one.

ah yes, that is one I have not tried.

I sure hope not. I think they are getting snatched up.

Looks like your right, I see them $29. You long range do ya?

@@NickBurnsFPV I wouldn't call it long range, but we have this bando hospital near me and it's just over 700 meters long so I've definitely done some 1km+ flights with it on 100mw :)

Nice, do you have plans for a more "science" sort of test?

@@NickBurnsFPV i have an antenna measurer thingy on the way but I'm not 100% certain if it will show anything. I was planning on side by side against my unify pro. I actually think it would win just based on not having to unlock

that would be nice, I don't have the equipment for that.

Nano only does 50mw. The $30 pro32 nano does 400mw

The one hglrc I had burned up :(

I have but like you said its not easy to know foresure we have done it right. Normally, I have to let it cool and try again when I didn't get the results I wanted. I won't act like I know just the trick, I have followed the instructions per blinks as to the band/channel/power settings. The number of blinks corresponds to the current setting.

200mW is a good power output, you don't overheat or saturate RF other eqpmts and you can go really far with a good directional antenna (10Km+).

I always desolder those. They tend to disconnect on crashes if not glued down in my experience.

@@VincentFischer i just use a stripe of shrink wrap and ziptie the antenna ... seems to work ok but your method is great too!

yea, often when we have specific requirements, we have to DIY. If they include a floppy antenna I am sure there would be a population full of "No no no" stiff antenna. Maybe two antennas in the package?

@@NickBurnsFPV yeah. for sure. fortunately i have spare junk everywhere so the DIY stuff is easy for me. I guess I assume a lot of these will go towards "toothpick" and micro class stuff which for a growing number are intro quads. and those people just won't have spare gear or a giant Quad Graveyard to pick through for the perfect part. two antenna would be great! I know the old BoldClash VM275t cams used to come with two spares for example.

Oh its only a matter of time for the newer pilots to collect all the spare parts and build their graveyard :)

shock, they make me a fool each time I mention price or sales...well maybe I do the fool part on my own :)

@Nick Burns I wouldn't worry about it, we all know the games they play with their sales prices, you only need to say 'at the time of making this video it was $price, but check the link for yourself in the description' :) bigclivedotcom has created a price effect all on his own, sometimes when he does a teardown of an interesting cheap Chinese sourced item, many people rush to get one and the marketplace reacts by upping the price!

I have seen some of Clive's video and his epic beard. Interesting to listen to. Does that drive his audience crazy?

He's got a nice calm voice, babies agree too because apparently parents put on his videos which helps them go to sleep! I take it you've seen his famous (don't let kids watch) Fanny Flambeaux video? The bigclivedotcom price effect does annoy people, but without his videos they wouldn't know those gadgets even existed.

I don't think I have seen that video of his. I will have to look it up. Does he get upset or something?

Its a good idea for someone with the inclination and time to take on such a venture. I am not that guy :)

@@NickBurnsFPV Yeah I didn't figure you'd be that guy ;) It's frustrating that Banggood (and Gearbest too) sell such cool products for good prices all the time because by the time they arrive at your door, it's on the verge of obsolete. Maybe we've just become good at seeing 6 weeks into the future and have to take it in stride! With great power comes... a cost.

This is a quad review video but same quad in both instances, in the linked video is with TBS unify pro32 nano kzfaq.info/get/bejne/Zqyin9V1ztTamXU.html

I really don't know what to make of this. I can't seem to understand what is written.

I know, I know. I am very cautious about updating my primary gear. I worry if something goes wrong then what. I will get to it someday :)

@@NickBurnsFPV FWIW, I've updated the firmware on mine like 3 times, it's gone perfectly every time, easy to do.

I have only once. I don't really think anything would go wrong with so many doing the updates.

Well, I guess looking like a fool is good for the wallets of others :)

I find when the vtx is under powered the reception is very poor. So poor that you might only get reception when withing a few feet.

If I were to not need the wires I would desolder them.

Its hard to say "easy" I have done it so many times. Basics of it is 5v and ground from board to 5v and ground in to the vtx, from 5v and ground out from the vtx to the camera. signal/yellow wire from camera to video in or vin and signal/yellow from vtx to video out or vout. Then the green wire on vtx to Tx1/2 on the board. Set the uart or tx number on the ports tab to tramp on the far right, save and reboot flight controller. All done.

I don't do much, I have used a number of these. I wouldn't wrap it in heatshrink, I just foam tape them somewhere it fits.

I have only used the skyzone 02X. I think the safer choice is the FS v5. The FS goggles have a pretty uniform fit, the ability to swap out rx modules and big time support.

Awesome! Thank you!

I am not sure there is a trick. If there is it could 1. putting it on carefully not to spread the outer edges of the antenna clasp, or securing the non-ufl end as to not put pressure on the ufl. We could use some e6000 glue, which will give, I don't recommend securing the ufl with strong glue as the impact could be to pull the ufl off the board, which would be bad bad.

Unfortunately, I don't have experience with iNav. Typically if we have the wiring to the correct pads we only need to enable tramp/smart audio to that port. Again, not sure how iNav expects it.

yes, not locked. I was running 3.5.7, I do think all version of BF support tramp, there is an issue with TBS smart audio and BF version.

The fight controller has the osd chip. We wire the camera to the flight controller, than from the flight controller to the vtx.

I have, the mic on it is not good for audio purposes, likely fine if you just want to hear the quad for flight not video purposes, but otherwise it seems to be the same as v1.

Yes, but we either need a different camera or we have to separate the camera from the attached vtx.
