RockSim is a rocket design and simulation software package that allows you to build and test-fly rockets on your computer before you ever purchase a kit or begin cutting parts for a scratchbuild design. Both a free demo version and the full version of RockSim are available from Apogee Components.








Rocksim Data
RockSim v7 and older .RKT files for all Public Missiles Kits:
These files include all Public Missiles kits for use in RockSim v7 and older for flight simulations. You can either view details of the flights included with each of these RKT files, or you can fly them with different motors than what PML did to see their performance. NOTE: The flights that created most of the Motor Recommendations Chart on the Specs Page are included in these files. Requires RockSim 7.0 or higher to run everything in the PMLRKTS.ZIP file. Most files should run on RockSim 6.0, and a few (mostly 29mm only kits) may run on RockSim 4.0/5.0.
