KC03 2.8MM 120 Degree 800TVL NTSC Switchable Camera with 600mW FPV Transmitter

Excellent value and performance. A great product and great price.

TL;DR: Setup worked when I powered it with 12 Volts (minimum for camera seems to be 5, minimum for VTX seems to be 7)There was I believe one or two people in the comments complaining about the LEDs on the VTX not turning on and there being an annoying noise. I had this same issue too when I supplied power via a 9V battery. The VTX didn't seem to properly function and I couldn't change channels and bands... HOWEVERDuring my troubleshooting process I questioned whether it was an issue regarding sufficient voltage. This time I supplied the VTX/Camera with 12V. It worked. The LEDs on the VTX turned on and I configured the frequency. The moment I turned on my FPV monitor the setup worked.

This needs at least 7v not 5v. Will not run off of my pwm receiver. I had to add an extra 2s lipo to power it up.

I wish you would provide all specs for this. I have no idea what type of connector goes into the Vtx. Mine broke, and until I can find the right connector it's useless. There are none available anywhere on the Internet.

In fact, I didn't get better performance from higher-price analog models that I tried.Just be aware that the included antenna is dipole -- so for best performance on freestyle quads (or indoors) you may want to swap it for a circular polarization antenna.

RP-SMA Antenna! Would have been nice to see that in the picture before I bought the wrong type. Seems to work ok so far, doesn't get too warm as long as you have some airflow to it. Camera connector to board harness is NOT the same on both sides (socket has beveled corners), but will connect if you force it a little. Seems to sip power nicely on a 2S. Difficult to find an elegant way to mount it, there are an offset pair of (3mm?) holes, but the board is double-sided so you need standoffs. No rear cover on the camera, minus 2 stars for that and the other small issues. You get what you pay for, seems to work for what it is, cheap way to see if it's something you want to get into.

Even with a power filter I got horrible picture quality and after only a few flights the transmitter suddenly stopped working. My PDB has a surge protector, power filter, and is short circuit tolerant. I have never powered the transmitter without an antenna either. Aside from lack of quality control I do not see any reason the transmitter should have failed.Update, AKK addressed the issue quickly and they have sent me a replacement. Their customer service contacted me very quickly and was very kind when addressing the issue.

Initial test shows very clear picture. I think this will work well!
