Model rockets are a great way to capture the thrill of the awe-inspiring full scale vehicles in a safe, budget-friendly form factor. But as the real thing evolves and adopts new features, enthusiasts like T-Zero Systems scale these advanced systems down to fit the miniature version,
as is the case with their 1/70th scale Falcon 9 rocket, which features real thrust vector control (TVC) like the big one.
The Teensy 3.6-powered guidance system even has aspirations to land vertically, although unfortunately the code is not available due to legal concerns. STL files and more information are available on the T-Zero Systems Patreon, however. The latest evolution of the software, which apparently borrows code from the space shuttle, can be seen in the video below.
