What a great review! of the rockets of the past. I dug a little deeper. I had to look more closely at the Extreme. That did it!! I joined rocketry in 1962 with the "little rocket that could" that was mailed in two tubes and it caught the engine as it was ejected changing the center of balance for a safe return.. From there came joining the NAR and building dozens of rockets. Recently I ran across a box with my left-over parts, and after watching your review of past designs, have kindled a new interest in rocketry. My grand kids and I will soon launch the first of many I'm sure. The Extreme will be our first. Thanks for over 60 years of a very rewarding hobby,.
