Concept

This rocket satisfies several basic design concepts for my Level 3 certification attempt:

• Most importantly, it is a Level 3 capable airframe & system, meeting Tripoli Level 3 certification requirements.
• In keeping with my hybrid penchant, the certification motor will be a 72" x 2.6" Ratt M900 hybrid, with a 12.5 second burn.
• In keeping with my Level 1 certification on a split fin Yank Enterprise Mystic Buzz and my Level 2 certification on a split fin BSD Thor, this rocket features a custom split fin design.
• In keeping with my previous hybrid rockets, Excuse Me has an oversized 98mm x 68" primary motor mount that can be adapted down to 75mmm or 64mm, allowing a wide range of motor & impulse choices for future flights.

Bonus brownie points for figuring out the double entendre in the name.
