The model airplane guys have a very small (about 15" long, 5"

about $3000 US.

How much for maintenance and fuel?

It burns a quart of fuel in a minute or minute and a half.

Is it louder than a gas powered weedeater? Just curious.

Deafening.

100,000 RPM with every harmonic ever invented.

I think they missed the lower sub harmonics, but who can hear
over that racket?

Some backpack fan powered paragliding. Looks like so
much fun, but dangerous.

Thanks to the replies.

I would imagine less dangerous than trying to in-line skate with one of
those things on :-)
