Man, who'd-of-thought I'd be such a nerd? I just recently bought a first person view (FPV) setup for my octocopter. This means I can now wear these goofy glasses and see exactly what I'm filming with my octocopter. There is a little camera on the octocopter that has a live video feed to these goggles, so I can view everything up to about a thousand feet away. I can actually go further, but if I loose the signal then I'm kind of screwed. I know...I look like a nerd, but to get professional video these are kind of essential. Right next to the little camera I'll attach my SLR to get stunning HD video.
