Mach Wave II Stage
Updated 11/15/21
This is my favorite rocket to date. A 4″ Madcow Nike-Tomahawk kit, it can be flown as a multistage or sustainer alone. I’ve done both several times, and I hope to keep flying this one in the years to come. Simulations show it can reach over 20,000 feet (6096m) on a K-K configuration, so I hope to do that someday.
I purchased this during a sale in May 2018, but the package arrived just after I left for my summer internship with NASA that year. I spent the summer planning its assembly, and how to turn the booster transition section into an altimeter bay. That was honestly the most fun part: experimenting in OpenRocket with various motor configurations, writing assembly steps and instructions for myself, and deciding the various electronics to include.
I built the sustainer in August 2018 and the booster throughout September and October. It flew in a boosted dart configuration and attempted multistage before successfully airstarting an H73J in August 2019, over a year after buying the kit.
