Very cool. What tooling are you using? I've found the world of FPGA tools to be bewildering to the point that I've abandoned my projects and my Nexys3 languishes in a drawer.
It's still in the idea stages, why my original idea of sending an FPGA doing active video processing would be computationally and energy expensive, where transmitting a low-latency signal to a processing unit on the ground wouldn't cost an arm and a leg. I'm looking at a ZYNQ-7000 board because the free eBook by Xilinx looked very approachable to a newbie at hardware design. If optimized properly, I'd hope to be able to integrate the quadcopter controls onto a better fpga and be a single unit. It's gonna be an all-summer project.
