Feyd, I don't know what caused the weight to jump on your version, but it was over 7 oz for a single-stage configuration. A C6-anything was just not going to lift that mass off the pad.

I re-built the design from scratch, which cleared out whatever the issue was. The mass in single-stage mode is now more in-line with where it should be. The flight simulation with a C6-3 gets up to 450', with a Dv average of 24 FPS. You will need a 48" x 3/16" launch rod.

The single-stage version is attached to this post, and I'm looking at adjusting some other components to achieve a two-stage configuration.

I used the "pods" feature to simplify some things.
