Building a flying model rocket is more than just putting together a couple of parts. You know that some rockets fly straight into the air, while others don't. The secret to a great flight is the rocket's "stability" ¨C your rocket has to be stable to make a great flight. Predicting a rocket¡¯s stability is easy with SpaceCAD, because SpaceCAD takes care of all the rocket science and tells you immediately. And even better: you can optimize your rocket, so that it becomes stable if it isn't yet. Don't let your hard, hours-long worked-on rocket be lost in a couple of seconds ¨C just because you didn't check its stability. SpaceCAD is the insurance for your rocket¡¯s safe flight! SpaceCAD makes it easy for you to design rockets. You can view them in 2D and 3D, you can zoom into your design and you can get see how your rocket will look like - before you even start building it. Just think of the hours won by tweaking your design to the max without sacrificing valuable material! But you'll also want to know how high your rocket will fly. The click of one button will tell you. It's really that simple! SpaceCAD also answers questions like - What¡¯s the best parachute for my rocket? - How high will my rocket fly? - What is the best delay for that flight? Just try it for yourself! Now that you have stable rocket design, you'll also want to build it. Just order the parts that you took from the element library (nose cones, body tubes, transitions, ¡­) through your reseller. For the fins, just print the fin cut-out pattern, the fin positioning guide and you are set. This makes building the rocket a lot easier. If you are more into building out-of-the-box rocket kits, SpaceCAD is also the best choice for you. Why? Rocket kits are not designed for maximum strength. You can and should change and optimize them. But changing a rocket also means that you have to check if it is still stable - and that's best done with SpaceCAD. So get your own copy today!
