I tried a FPV system on my stug a few years ago. It was a primitive system by todays standards, as in, I watched the camera feed on an old TV, and it only worked for about 10 minutes, but it was cool to use. I drove the stug all around my basement, even into other rooms, before the system quit working. I never tried it again but may someday. It was cool driving the tank that way.
After that I wanted a system with two cameras, one on the hull pointed forward for the driver, and one on the turret aligned with the main gun so I can pan around to look for targets. But then I need a friend to help operate the tank...
