3 2 1 Blast Off!

Well last week my brother finished a few rockets, and they were finally able to take flight. One rocket was a four D-12 cluster, which he received 10 year ago. The other was an Arotech Cheetah, which can run on a variety of engines. We were only able to test two, since we lost it on the second. The first shot was with an E-30, and the second lunch was with a G-80. The biggest motor with out certification.
