What type of rocket motor is typically used for Level 1 Certification launches?

The correct answer is that a motor with a maximum total impulse of 80 Newton-seconds (N-s) is typically used for Level 1 Certification launches. This certification level focuses on ensuring that the candidate has a good understanding of rocketry principles while launching rockets that are manageable and safe for beginner to intermediate hobbyists.

Using an 80 N-s motor strikes a balance between providing sufficient power for the rocket to reach a reasonable altitude while still being performance-oriented for someone at the Level 1 Certification stage. It allows for straightforward launches that help the candidate demonstrate their ability to handle assembly, launch procedures, and recovery.

In comparison, motors with a total impulse of less than 80 N-s may not provide the necessary capabilities to reach the required altitudes or speeds for a meaningful launch experience. On the other hand, motors with unlimited impulse capability or those above the 100 N-s threshold would require more advanced knowledge and skill, making them inappropriate for Level 1 Certification as they increase the complexity of the launch and recovery process significantly.
