Reese_000 assuming that you are talking about the RC832 FPV receiver, you should be able to stick the RCA jack from the monocular into the middle jack in the rc832 receiver. If you are talking about a different receiver and have AV cable outputs, then you can get an AV to RCA adapter and it should work fine, or you can cut the RCA cable and solder the video wire from the RCA cable to the yellow AV cable.

Reese_000 it has positive, negative, and analog video.

Reese_000 480p is the only resolution for this specific display but you might be able to find other products with slightly higher resolution elsewhere

Reese_000 none it can barely carry the camera. I bought some slightly larger than stock batteries and it kept falling out of the air at max throttle.

Reese_000 most people would probably recommend the EV800D or EV800. EV800D has dvr and diversity antennas for better directional range compared to the EV800.
