Here is a new paper Ready-to-Fly rocket from Sergio Moalli. Sergio lives in Varese ( a little city near Milan, Italy). This is Sergio’s first design submitted to the Rocketry Blog. Sergio suggest using heavier cardstock (if my conversions are correct he suggest 110 lb).
Sergio says “My hobby is 3D computer graphics and my passion is build and fly paper model rockets.”
