What defines a class 1 rocket?

A class 1 rocket is defined by its maximum limits on propellant weight and total pad weight, specifically allowing for a model rocket that contains 125 grams (4.4 ounces) or less of propellant and has a total pad weight of 1500 grams (53 ounces) or less. This classification is crucial because it sets clear standards for safety and performance related to model rocketry.

Particularly, the specified weight limits ensure that the rocket can be safely launched under controlled circumstances, meeting regulations that aim to minimize risk during flight. Such parameters are especially important in hobby rocketry to ensure safety for the rocketeer and the public.

The other choices do not accurately align with the established definitions for class 1 rockets. One option mentions a model rocket with 100 grams of propellant, which is less than the class 1 limit, while another incorrectly describes a larger rocket capable of carrying payloads, moving outside the specific class 1 framework defined in rocketry guidelines. The final option suggests there are no weight limitations as long as a recovery system is present, which does not conform to the class 1 requirements.
