Rocksim Design File
Comments: Estes #3031 Rocksim by MMD 11-20-2011 Classic Series release of Centuri KM-3 Note that the tubing coupler supplied with this kit is 1" long. The kit instructions state to install the coupler halfway into each tube. If the kit is assembled in this manner the motor overhang will be 1/2", reducing stability. Inserting the coupler 1/4" into the rear tube allows a more typical 1/4" overhang and a safer stability margin.
To use the design file above, you need a copy of Rocksim, a rocket design and simulation program.
