Model rocket

Model Overview & Print Notes

Compatible with the B4-4 motor (69mm x Ø18mm) which is legal in most of the world, including Europe. Reaching an apogee of around 80-100 meters at speeds up to 38 m/s and 117 m/s² max acceleration. The parachute is secured with 2x M3 bolts. The parachute should weigh in at around 10-15 grams. The launch system requires a rod (6 mm for this design) for the rocket to steer in the first meter or two. The B4-4 motor has a parachute discharge that triggers 4 seconds after burnout, therefore make sure that the nosecone isnt too loosefitting or too tight (I used electrical tape to add diameter and sandpaper to take material off).
