Adafruit customer Joe Barnard wrote in to share his really cool model rocket project with us. His website is impressive and has lots of information on his experiments in rocketry so be sure to check it out!
…Barnard Propulsion Systems is a platform intended to further knowledge and understanding in modern rocketry by experimentation. Right now, the primary goal is to achieve VTOL (Vertical Take-Off and Landing) of a model rocket with fixed thrust, solid propellant motors.
The challenge is difficult, but through small advances in stabilization, coding, and lots of trial and error, bit by bit it can be accomplished.
