MetMan's posting about his V-1 suggested to me that maybe I ought to share with you all my Rhinebote project.
The Rhinebote was a German WWII artillery rocket. It had four solid propellant stages, each with six fins. It's been difficult finding accurate scale data, but I was able to get workable dimensions from the overall dimensions and from the few drawings available. The booster is BT-80 (2.6"); the 2nd and 3rd stages are BT-55 (1.325"),and the 4th stage is BT-50 (.976"). The diameters using these tubes work out to be within 5% of scale. There's a BT-50 motor mount/stuffer tube that runs up through the 1st and 2nd stages, and halfway up the 3rd stage, for rigidity. The parachute goes in the upper half of the 3rd stage, and the entire 4th stage acts as the "nose cone".
Here's an overall picture. The next few messages include some construction photos.
