Hi China

What was the pressure on those first rockets. They didn't fly very far. The second one was really cool though!

You don't want them to fly very far when firing them at an angle, lest they leave the boundaries of the field. 20-40 psi is more than sufficient.

I like the ribbons on the fins.
