Default Estes Python 2129

There is much misinformation about this kit on the internet. The payload tube is 12 inches long not 11 as in the Estes body tube length tables made by John Brohm. I get a full length of 34 inches not 33.3 inches as in the 1997 - 2000 Estes Catalogs. I created this RockSim file from a kit that I finally was able to obtain. The dimensional measurements are correct; I haven't fully opened the kit and weighed all of the components. I have attached the RockSim file which should allow for easy up or downscale (as well as 3D printing or turning of the complex nosecone shape) and a few screen shots from the simulation file.

The nosecone and transition I 3D printed using the data in the RockSim file I posted came out great, see attached pictures. The 3D printed nosecone is on the left the original from the kit is on the right.
