About this 3D model

**UPDATE 2013/08/07** Added files for B/C size engines (and some A's) Tested 2 stage rockets with both A and B size engines -- They both fly great. **Videos:** https://www.youtube.com/watch?v=mGV658F-S14 https://www.youtube.com/watch?v=yqqz5XzA2GQ https://www.youtube.com/watch?v=YmJDoERuGF8 https://www.youtube.com/watch?v=OEV92Uavh04 --- Just a simple nose cone and tail fins that can be attached directly to a model rocket engine to become a complete rocket. (Thanks to my friend Chris for the idea). Files are included for both 1/2A size, and B/C size. This thing flies great as long as you use the guide tubes on a proper rocket launch pad. I just used a bamboo skewer in a block of wood. Just make sure it slides off easily. The single stage version shot off the launcher, and was amost out of sight in seconds, until the ejection charge created a puff of smoke in the distance. Don't launch direcly from the ground without a guide rod (don't ask me how I know... sorry Chris) Don't plan on recovering the pieces, since they will probably not survive. That is why it is called a "Disposable Rocket". It only costs around 25 cents in material to make, and 15-20 minutes to print. I am in no way responsible for how you use this, so please use good judjement in launching it, and please don't launch near people, buildings, or other important objects.
