SpaceCAD tells you if your model rocket is stable, how high it will go and which engine you should use. You don't have to be a rocket scientist to build rockets with SpaceCAD!

SpaceCAD calculates the center of gravity and the center of pressure to determine the stability of your model rocket. You can see your model rocket on the screen.

Clicking a button, SpaceCAD calculates how high your model rocket will fly. You can print a comprehensive infosheet (printing disabled in demo version) and a fin guide.
