Hey everyone,

some pictures:

We'll probably have some more to post in a week or so. Any feedback is welcome!

One comment :
"From what we've seen so far, most of them run from $200+, and they also are mostly designed for very low outlet pressures (<150psi). "
I would suggest that designing experimental rockets for 150 psi feed pressures is a good idea. Lots of industrial stuff is designed for 150 psi working pressure, and you can save a lot of money over going to higher pressure stuff. You only wind up with a 2:1 expansion ratio or so, but all the other rocket lessons are going to be the same, and if anything does pop, it will be a less violent pop...
