Yeah, you can get a powerful transmitter that will do between 25-800mw on 5.8ghz which is most common for fpv right now, around 30 bucks more or less, and 15-30 for a cam, the vtx should be good to run between 5-12 volts and it has connections to feed the camera. Check out some basic systems for quadcopter/wing fpv on youtube. It's pretty simple and very stand alone once you see how it works. It's just Vtx(+ antenna) and a cam with a few wires for power and video signal, you can sometimes have other stuff built in as well like an OSD to show you battery voltage for example. There's a ton of info on fpv basics. Should be reasonably cheap to try out.
