I have 3D printed a beautiful Mercury Polecat capsule, and am thinking of building the Redstone sustainer for this thing. My questions being, I know the polecat kits have been OOP for years now and I seem to be having trouble finding any old dimensions for the original especially airframe length, diameter is 5.38, and fin specs. I suppose I could scale the actual rocket but I know sometimes this looks very disporportional in real life. Thanks for any help.
