Black Mamba FPV VTX 5.8GHz 6V-28V, 40CH 2000mW FPV Transmitter for Long-Distance Transmission 8 to 9km (TX5820 V2-SMA)

I take back what I said earlier. It works great! All you have to do is switch around the video and audio wires. The instructions have it backwards.

I am more than pleased with my Mamba!! Strong signal with crispy clarity!! Recommended!!!

Hello everyone,I have to say that this VTX equipment once I had it working, is awesome!!Having said that, I only give 4 stars because of the process to make it work, and because of the actual reason why it did not work in the first place.When you take a look at the pictures, you will notice that the yellow wire, internationally recognized as the video in/out line on any composite video equipment, and the white wire, usually means an audio in/out line. So I matched the colors and connected everything.Nothing happened....Well, after 2 hours feeling that I am the unluckiest guy on Earth, I thought... maybe the audio (white wire) line must be connected to something (some monitors require this to work properly, I do not know why). To my surprise, I had a video feed on my monitor!!!In the end, checking the wire colors vs their plug position, I came to realize that the white and the yellow wires were swapped, i.e., the white wire is in the video line and the yellow wire is in the audio line.MY SUGGESTIONCheck the position of the wires before connecting everything, it could save you time, sweat, and maybe money.For this little but meaningful mistake, I qualify this with four stars, just because there are no 4.9 stars....One of the attached pictures is the advertised picture, the other one is from the actual product I received.

Theres all kinds of warning to make sure antenna is installed before powering up. Well it didn't matter with this one. With antenna installed I powered unit on and the channel display showed (--) so I pressed the channel select button and display went blank. Then came the unmistakable burnt electronics smell. Giving the benefit of doubt I still tried it and sure enough no signal was being broadcast. I say look elsewhere for TX, hope this helps

I had a FlyZone 2000mW (or just 2 Watts) and for some reason it just was getting too hot. Eventually the voltage regulator finally went out. This one has a good and a smaller fan but I've added another along with a larger metal heatsink and so far it is doing great. Just remember the more power the more heat will be generated so you have to compensate for that in some way.
