How to Build a Rocket for L1 Certification (Vulpes II Rocket Launch)
Published at : 23 Dec 2025
In 2023, Max launched the second hobby rocket he's ever built. The Vulpes II is an L1 certification rocket, meaning that he built it to meet certain requirements so that he could obtain the certification to purchase H and I class high-power rocket motors. Getting to an estimated apogee of 1400 feet and successfully separating, the Vulpes was recovered intact. The Vulpes’s motor was single-use, but its intact structure means that all it would need is a new motor to launch again. Learn all about the Vulpes and how you can build your own L1 certification rocket in this Graviton Media video. An unedited video of the Vulpes’ flight is also available at the link below. We hope you enjoy the videos and learn more about hobby rocketry.
