Shastas Rocket Site
Squirrel Works




At last, the stubby little rocket so loved by our mascot squirrel is available as a kit. The Acorn features “Through the Wall” fin mounting, using laser cut slots in the body tube for precise fin placement, this makes the kit easy to build for the novice. When launched on lower impulse engines, the Acorn makes a great small field flyer.
