Based on my Single-Perimeter Rocket for Seamless Spiral Printing http://www.thingiverse.com/thing:458903
This cutaway shows the major components internal to the German V2 rocket from WWII.
The model is about 5.75 inches long when printed at 100% scaling.
Solutech Silver PLA, 225C filament, 60C bed, 25mm/s Spiral Vase mode sliced in Slic3r. Position on bed is X=90, Y=0, Z=-61, One perimeter. Fuselage shell is 1.2mm thick at 100% scaling, so extrusion width must be .6mm or less. It's best to have layer fan on 100% through entire print. The last 6mm of the very tip will likely be wobbly due to heat buildup, depending on the material. Reducing temp and speed during that portion of the print may help, otherwise be prepared to clean it up with your x-acto knife. If after slicing, you see glitches (missing layers) in the rendering, try rotating the model by 1 degree around the Z axis until it slices cleanly. Minus 61 degrees worked for me. Slic3r's spiral algorithm is sometimes sensitive to the starting point. If you can't eliminate the glitch, try printing it anyway - often the layer above will fill in the gap and you will just see a faint line because those two layers are narrower.
