The model airplane guys have a very small (about 15" long, 5"
dia) turbojet that they use on scale jet R/C planes. It costs
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?
