I've used FPV off and on for a number of years. I like it a lot but always seems to get pushed to the back burner. I just purchased some micro cams and receiver and plan to use them
I'm very interested in the announced FrSky X20HD which is supposed to integrate real time telemetry AND video right to the transmitter's LCD screen. No release date has been given.
My use of FPV has not been without ups and downs. I recall once at a model show I was using a (can't recall the maker) a system called a Microplate or something like that in one of my 1/10 Tigers. There were a number of vendors and other with monitors showing various video and when I fired up this thing the iamge from my Tiger superimposed on several monitors near me. Scared the crap out of me as I'm well aware of FCC freq regs and power limits so immediately shut the thing down never to use it again. I have no idea how much power that thing generated but discovered later that it required a amateur license to use legally! My dad was a lifelong HAM and all he did was shake his head at me...
Here's a snippet of a longer old video of a Panther with FPV, not very good or clear. This one was streamed to a PC and captured that way: I made it in 2007...
