Actually, you do if you'll exceed a certain height or if your rocket engine is larger than H (or perhaps I) class.
- jonnycowboy 11y agoH or I class rocket engines are definitely not "park rockets".
- Florin_Andrei 11y agoYeah, H class requires level 1 certification from Tripoli or NAR. And for good reason I'd say. I just happened to launch an F-class yesterday - definitely not your kid-friendly little model rocket that you could launch from the baseball field nearby; that things goes far and carries quite a bit of mass. If something goes wrong and it shoots into a person, it could do some damage. https://en.wikipedia.org/wiki/Model_rocket_motor_classification https://en.wikipedia.org/wiki/Model_rocket_motor_classificat...
