these guys are still basically playing with RC planes. Many of the so called drones are completely ground controlled. I guess I should tell my girlfriend I'm spending the weekend working with UAV's and that the little helicopter is actually a "drone".

Micro in the hobby theater is much smaller. Micro aircraft are often ten inches or smaller, weighing in much less than a pound. I've got a "UAV" here on my desk that's only a few ounces, but it can't handle wind and hates the aircon drafts.

There are even already tiny "parkflyers" with less than half meter wingspans that can fly for 20 minutes or longer on a single charge. Guys build them for less than a hundred dollars with gear. Cheap cameras are available-plenty of homebuilt "drones" costing less than a hundred pounds sterling with better performance than many of these things police and government are being sold. And they're smaller. If the hobby industry wasn't about the fun and skill of flying these aircraft, then we'd already see micro scale autopilot and GPS guidance too.

Maybe someone needs to show them the Tower Hobbies catalog?

or, how long until this fuel cell stuff is available for high performance pylon or pattern racing hobby planes? :)
