    A spare 5.8GHz 200mW TX5823 arrived from BangGood yesterday – 7 working days since the order, not bad for the festive season. I assume it is the new 3.5 – 5.5V model since it has a different number (TX5823-120228) to my original 3.3V one. The BangGood documentation is confusing however, as it reports Vin of both 3.3V and 3.5-5.5V. The Vtx is for a #16 V2 camera plus VTx daughter board configuration - initially for my V262 quad, but movable to any other aircraft such as my AXN Clouds Fly (see photos) Initially I hooked it up to a single 1S 150mAh LiPo at 4.05 volts to Vin with my #16 V2 keychain camera providing video in, and antenna out to a cloverleaf antenna. I didn’t connect any of the channel selection pads so the VTx should have defaulted to channel 8, 5945 MHz for this model. I set my RC305 VRx to channel 8 and switched everything on. No joy, and the TX5823 was heating up rapidly, as has been reported elsewhere. I ran through the RC305 channels quickly and on channel 5, theoretically 5885 MHz, I got a picture on my 4.3” LCD monitor . I don’t know which device is on the correct channel. Since the VTx was heating up so much I decided to try it on 3.3V. This required an input of 2S into my AMS1117 3.3V regulator to produce 3.3V (it didn’t work on 1S) and this got extremely hot , so I decided to return to 1S with no regulator and to cool the VTx with a heatsink and the quad prop blast. An excellent, light VTx, which the V262 can lift easily at an AUW of 238gms.

    low-cost, small and lightweight audio and video transmitter. due to its size and weight - can be used by small aircraft and quadrocopter. Plant manufacturer claims that the power of the transmitter enough 1s battery. but I soldered a stabilizer. the results of using this transmitter you can see here:

    I use this chip for a micro FPV set, using a 12.7mm antenna wire, and a small camera (also from here), I made a 6.1 grams fps set, including battery, for use with a micro quadcopter. Have ordered 3 or 4 of these, all work superb. The 10mW version is good too, but this one costs a fraction more, and transmits with more distance. I use a little 1s lipo for powering the VTX, and use the VCC and ground on the camera and VTX at the same time, no problems. Ordering some more, as I got a few friends hooked to FPV- this chip, in a FPV set on a Hubsan x4, is just perfect, and the Boscam recievers work great with these. Range is about 500 meters for me- which is too far for a micro IMHO, but nice to have range, than find your quad after video loss.

    Lightweight and powerful. It can be powered from 1S lipo. I connect it to battery with 1A schottky diode in series to lower the supply voltage and thus reduce transmitter heating. This also helps to avoid battery overdischarge.

    La petite taille de l'émetteur permet de l'utiliser sur des petits modèles RC ou quand on est limité en espace, fonctionne bien. Si vous utilisez un lipo 1S, mettez une diode en série pour faire chuter la tension de 0,6V, vous serez ainsi plus proche de la tension max d'alimentation de l'émetteur qui est de 3,4V ou mieux, utiliser un régulateur low drop(LDO)

    I think most of the time you get what you pay for. With this vTX, you get a little more than what you pay for. If you do it up right the first time, you'r golden - hella bang for the buck. But if you change your connections, or aren't a perfect solderer, you might just ruin it. Reason being, the solder "pads" on the sides are really weak. My first install went fine, soldering necessary wires and dipole antenna. I wanted to repurpose it and when unsoldering I probably pulled the wire off a little too early, causing the pad to rip off. I barely used any force at all though. I had to take the heatsink off and find a place to connect to instead of the external pad. I haven't tested yet, so wish me luck. Another thing is heat. Running on a 1S battery makes this thing quite hot. I'm reading now, it COULD be because the antenna might be less than perfect, but I've seen other tests that show it getting hot too, with a perfect antenna. I see there's a voltage regulator on mine, since I pulled the heatsink off, but I don't dare trust it. I'll be using an external regulator from here on. Other tests I've seen show that at 3.3v you won't get but about 100mW out of this. And around 160mW at 5v. The reality is, that's plenty for a micro. How far do you want to go with it?? With that little dipole on 3S I'd say it went farther than my control signal, so good enough! I'd recommend this one... just be carefull with those solder pads, and run an external voltage regulator.

    Been using this kind of tx for a while now. Have two of them, both on microquads. Flying around apartments about 400 feet around, covers indoor/outdoor.. Entire house upstairs and downstairs in every room and closed. Tried even flying around the 12 apartments building, with only a little bit of snow on the opposite side. If size and wait is imortant, I would not go any further than this. The entire FPV TX Antenna and Camera are 5g only.

    I have ordered these from the main warehouse its out of stock at the USA, that is why I wanted to post this, I don't mind ordering or waiting for parts or items I understand things take time but when I read about people buying as many of a item that they can (like 15 -25 pcs) and then read the comments about how they like to buy all of them then brag how the have so many and no one else has any then they laugh about it (I am sure some of you that may read this have met people like that at some point) and offer to sell one or two at twice the price! it gets me Pissed Off to be honest Like I said I don't have a problem with people buying a few or making a buck or two but to be that extreme just really gets to me so maybe a limit of some sort per order would not be a bad thing and cut down on the selfishness that has no place in our hobby just my tow cents I don't know if they will even post this statement, I just had to get it off my chest as it has been eating at me for a Long long time & not just here at BG either I've seen and read it at most of the on line place s that I order from

    I ordered this module along with a matching Boscam 5.8GHz receiver module to use it for FPV. Later I realized that here in Germany 5.8GHz transmitters with more than 25mW power are prohibited, so I ordered another transmitter with 10mW, which I am using now. I tried this one out anyway and of course it works much better than the 10mW one - stupid German RF laws! I would buy this again if I was allowed to use it here. Shipping was quite fast btw.

    This is a nice tiny video transmitter for mini or micro machines, it only weights something like 7g with a cloverleaf antenna, i have one and works just perfect. Nice job banggood
