Scale It! is used to determine the best fit from available hobby rocketry body tubes to the diameters of a real rocket. Scale It! can determine these all on its own, or you can select the tubes you want and Scale It! will analyze your choices.

Version 1.2 is way alpha; it works pretty well, but has no help and only minimal documentation. 1.3 is on the way, but wRASP32 development is taking precidence at the moment. Still, bug reports for Scale It! are welcome.
