3 This is a test stand Bdale built for testing research motors.
7 There is a lot of fun and education possible using only commercially
8 manufactured hobby rocket motors. But making every part of the rocket
9 including the motor has some allure... and being geeky sorts, getting
10 good data on our experiments seems pretty important.
