OMFG so if I can build a thing within these constraints I can fly it?

(1) Weighs less than 254 pounds empty weight, excluding floats and safety devices which are intended for deployment in a potentially catastrophic situation;

(2) Has a fuel capacity not exceeding 5 U.S. gallons;

(3) Is not capable of more than 55 knots calibrated airspeed at full power in level flight; and

(4) Has a power-off stall speed which does not exceed 24 knots calibrated airspeed.

God Bless America!

Yes. You need not even build it yourself, you can buy it. eg: powered paragliders

Powered paragliders look like fun. You can fly from your backyard to McDonald's for lunch and fly back. https://youtu.be/rvQ9DjJNal0

Peter has become some kind of guerilla youtuber. I have seen him on at least six different channels in as many months (most recently https://www.youtube.com/watch?v=LEZCxxKp0hM).

The funny thing is he's about the only one I'd actually like to meet in person. Nothing against the other folks (Mark Rober from above seems really nice), Peter just seems like he'd be fun to hang out with and build something.

So this is how I die...

Worth it. ;-P
