Modeling the SA-5 in 1:165 scale (only 11.8" tall!)
This model uses cast polyurethane resin parts for the interstage
shroud, fins, details, and nose. The clustered tank tubes for
all
three scales are custom wound around a brass tube. The decals
were drawn in TurboCAD and printed onto clear decal stock using both a laser
printer
and an ALPS MD-5000 printer.
The model
flew on an A10-3T motor with a piston launcher. Total weight with parachute and motor was
about 2.5 oz at liftoff. The flight
ended
up lower than anticipated because of premature separation from the
piston,
but the altitude was sufficient, nonetheless, and it won 1st place in C Division at ECRM-30 in Middletown, Maryland.
I was pleased at how the model turned out, but I built it in this scale
simply because of the 30 cm length (or 2 cm diameter) constraints of
the Peanut Scale event. I would prefer to build larger models of
the Saturn I. See the project page for my 1:59 scale Saturn I.
