I was looking into getting a helmet-cam when I though of how cool it would be to have a drone with a cam filming me from the air. The ultimate dash-cam. A little research told me we have the technology for guiding and flying, but lack a reasonable battery-life, and top speed may also be a problem.
Can anyone with more knowledge or insight with drones give a guess at how far off something like that is from commercial availability? If someone was dedicated could anything like that be made with todays tec?
Is 1 hour at up to 200 km/h an unreasonable hope?
