New Design -- Star Legionnaire
I'm going to post this design now, as R9 seems to have been corrected for the length error. The latest update -- 9.0.1 f69 -- calculated the length where it ought to, and the simulation runs suggest the design will actually fly.
Length: 33.00"
Diameter: 1.04" (ST-10)
Fin Span: 4.98"
Weight: 2.75 oz
Average summary of 10 runs:
C6-3......415'......Dv between 9 & 11 FPS......48" x 3/16" rod
Keep in mind the need to provide gas passage through the pylons, as the parachute is in the forward pod. I suggest using several 3/16" launch lugs in parallel, built into the pylons. The pylon patterns are not solid blocks of balsa, but should be hollow, with the lugs sandwiched between two outer skins. These skins could just be pieces of cardstock, with an inner structure of balsa to take the loads.
Enjoy!
