This is a design that I started in 2007, with a not-so-clean rendering created with an earlier version of RockSim. I began a RS9 version as soon as I got the package, but it had some simulator errors that made me set it aside for awhile.

The model is an offset-centerline style, with a ducted ejection port to the forward fuselage. The original design used 18mm C6-5s, but this version seems to work just a little better using 24mm C11-5's.

Length: 37.50"
Diameter: 1.34" (ST-13)
Fin Span: 11.32"
Weight: 2.61 oz


C11-5......~570'......Dv ~19 FPS......48" x 3/16" launch rod


Patterns are available for the fins and the offset centering rings (next post).

Enjoy!
