YouTube user BenNBuilds made this FPV snow sled a few years back – and it’s awesome! He installed a 900 MHz video transmitter onboard so he could watch the action as he zoomed around at ground level. He says that the video quality isn’t that great, so instead of using goggles, he just displays the video on his laptop screen.
With a better FPV camera, the video quality would improve dramatically. But still, even with the grayscale video output you could still have a lot of fun with it. Not to mention, you wouldn’t have to worry about crashing into anything (which would probably happen frequently!)
