This is my receiver for recording my FPV airplane flying videos, outputted by a generic all in one vtx+ camera on my powered sailplane. It outputs to an old return Toshiba Encore 2 8" windows 10 tablet via the included double sided male micro usb (not that there's anything wrong with that) and via the automatic search function finds the strongest channel frequency and locks on (provided user activates the vtx first, obviously) and does it's job well. It's reliable, easy to use, low power consumption, inexpensive (literally the cheapest one I could find at the time) & delivered super fast. I have no qualms or reservations about recommending this to anyone or buying another myself for any low end beginner FPV setup. Designed to output to an OTG capable cellphone,which I've also done with this successfully, but works great to a laptop, tablet or anything that can accept video in via usb. Also has a 3 pin input that I think is for either an osd or perhaps an alternative power source (otherwise powered by USB).

The Skyzone app is rubbish, wouldn't even load for me. Tried a number of otg /webcam apps till I found one that worked. USB camera worked for me, but I suspect results will vary based on your device. Other than the app, the system works as expected thus far. It's a compact piece of kit, great for spectators, and much cheaper than a second pair of goggles or a system with built in screen

I bought this to use with a micro drone (think toy drone) that I soldered a cheap FPV camera onto. It does quite a good job. I ordered a 5.8 ghz wifi antenna that screws into it, and seems to get a bit better range, however the dual camera/vtx I bought just doesn't output enough to get more then a few hundred feet anyway.

I can't testify for the phone app, although I'm sure it's not great. I have only used this with OBS on my laptop. It pulls up as a USB webcam so i'm sure you don't have to use the device's native application. Any program on a laptop/mobile phone that can make use of a USB camera will do.

It's definitely worth the money if you have goggles without a dvr or just want a second display.

Just editing this review after getting true FPV goggles:
Ok so after getting proper fpv goggles,I can confirm the issue is not with the transmitter but the receiver on this thing. My goggles pick up video far past this device, even with the stock dipole antennas they came with. The resolution is also much better in goggles. However, this is 35 dollars, and it works with any device that accepts webcam input. So it is still a good secondary buy. Just grab a few external antennas and experiment to see what works best. height is important here. It is much cheaper than an entire set of goggles just for a secondary display. You could even stream your flights with this if you really wanted to, since it is recognized as a camera.

Software that it recommends doesn't work. Try "go fpv" and do indeed click on Airplane Mode.

The product works great, I use it as a secondary backup for my fpv flights and so my girlfriend can watch without getting motion sick. One big caveat: DONT US THE OFFICIAL APP. use any third party "USB C video capture" app from the play store for Android. The official app is broken and does not work, but it is plug and play with any other app. I use "USB camera" and haven't had any issues.
