The youth from the 4-H Club wanted to fly eggs in rockets. Yes, that is a thing, actually a contest event in model rocketry. Get your egg back safe and sound is part of the scoring in this contest. SARA (sararocketry.org) was there at Udhall park to help out. I got to fly my 3D printed 24MM Sport on a D12-7 motor, probably around 1100 feet. Nice day in Tucson.
You can print it: Here are the files needed to have one of your very own 24mm Sport Rockets.
