It’s great to rediscover a childhood hobby.
Although, as a kid, I only built the simple Estes rockets and couldn’t quite bring my self to launch them vertically since there were so many more interesting targets on the ground….
Here you see an H size engine mount, and a parallel Estes mount (takes two D or E sized Estes engines). Each successive letter grade (from A to M) is roughly a doubling of total power. You can go to G sized engines without a license.
With a simple Estes rocket, you can use masking tape to make a two-stage rocket out of a one stage design…. and some random things can happen.
