Thanks, Randall.

We built the engine and airframe, and will be flying it this fall.  
Current simulations put it a bit over 8400 feet, which is reasonable  
for such a heavy engine.

I saw the article on Lozano in Popular Science, it's quite a story. I  
administrate an international forum that includes rocketry and manned  
flight ( http://wwww.pulse-jets.com/phpbb2/ ) and rocket belt  
projects are always popular discussions.

If buying a machine is the best route, why is ERPS rolling their own?

Thanks for the references, I'll look them up.
