Shastas Rocket Site
Squirrel Works




This rocket was originally designed and sold by Thrustline Aerospace before the company ceased operations. It is such an elegant design we thought it should be made available again. We contacted the former owner of Thrustline, acquired the design and now offer our version of this classic rocket.
