I see by looking at all those shots of Eric Scott that ectomorphs only need apply for rocketbelt flights. Double drat it.
It's the Cold Equations: hydrogen peroxide allows you to make a simple, light, and relatively safe rocket belt, but it's got mediocre performance, so you have to consume propellant at a ferocious rate in order to get enough thrust to lift the device plus the pilot. And there's a limit to the weight you can carry on your back.
The cruel numbers, which I posted the other day, are 47 pounds propellant, 83 pounds empty weight, up to 300 pounds of thrust.
I suppose you could make one that had more thrust than the original Bell Rocket Belt, but it would have even shorter flight time than 20 seconds.
Heavier people might consider a design like this one, Bell's POGO, which was made from parts of two Rocket Belts.
