Fun Size Saturn V
Years ago I built a Boyce 1:396 Saturn 1B. Well, I used the nose cone from it, but the rest of the parts I wasn't happy with, so I used my own and created waterslide decals instead of the paper peel and stick that came with it. I used half round plastruct for the tank tubes and plywood for the fins. The rocket has been a well flown favorite, and as it was assembled with epoxy has been a tank, even surviving some CATOs with no damage.
I decided it needed a big brother, the Saturn V. After getting the scale data for a Saturn V, at first I created a similar 3D printed version of the 1B nose cone printed with 100% fill for weight that would fit in a Centuri/Semroc ST-7 tube, but then I decided to just make the whole top portion the nose cone and 3D printed. I did a 50% fill so the nose would have ample weight for stability. I sized it to fit an ST-10 Centuri/Semroc tube. For the fins and fairings I resized Scottdee's BT-80 version to 40% and attached them with epoxy. https://www.thingiverse.com/thing:2941984 I'm fighting a little tuning on the print for the nose, I'm getting some undesirable layer banding. a little sandable primer will resolve it. I'm going to create a body wrap for it. It currently weighs 37 grams (1.3 ounces) without a motor mount.

Made a lot of progress on the little Saturn V today. She's almost ready to fly.

The #2001 is easily identified by the ridiculously GIGANTIC fins.

I got all the little detail bits glued on.
Now, just need to decided where to put the launch lug. Then she's ready to fly.

Finally got a chance to launch the little Saturn V on an A10-3T.
CATO!!!!! Nose cone is okay, but main body is destroyed, burned up inside and not really repairable. Tube is soft and squishy. Parachute melted to the outside of it. It blew out the ejection end of the motor.
