Greetings,
I have had a design for a rocket that I want to build using a plastic model at 1/350 scale as a template. I have several questions, and more than a few roadblocks in my way. The plastic model is 30mm diameter, so I first want to upscale it to an Estes BT60 body tube which is 12mm larger in diameter than the diameter of the plastic model. That is simple to figure, add 12mm to all diameters to get the correct scale. What I don't know, and this is my first roadblock, is does this also mean adding 12mm to the length, fin measurements, ect. to get the correct scale for the rest of the rocket design? The design itself will eventually be up scaled several times, but I first want to test flight stability on a small scale, using a c6-5 motor. I tried a trial version of ROCSIM and found I am lacking the degree in engineering needed to understand how to utilize the program, so I am going old fashioned, graph paper and rulers. I know someone out there has done an upscale, so help me get this design to lift off.
