Captain Electric's Saturn Screamer Rocksim Design File

Comments: Transition base drag effect and fin pod CP/CG adjustments by Bruce S. Levison (as amended by Geof so it's all my fault) Note to self: remember to readjust CD if windshield changes. Right now, it is calculated as .439+2*.141+.148 I did not use the fat fin approach to approximate CD of pods; I found their CDs as separate finless models. This version has mass of body adjusted for fiberglass build. Also, instead of mass override, I chose materials and thicknesses for segments to yield correct weight and correct CG of nose-less rocket.

Designer: Geof and Jim Givens
