The "Rheintochter"
This was a WW II German surface to air missile, that was made of metal, but used plywood for the control surfaces. Here is a model of what it would have looked like. 82 test launchings were made, but the weapon was never used in combat by the Germans during the war.

There was a fellow named Ray King who entered one of these in Sport Scale at NARAM-60. Very interesting model. As I recall the flight didn't go all that well, though. Clustered and staged. Pictures from the November/December 2018 Sport Rocketry.

Your second picture looks like the one at the Udvar-Hazy Center at Dulles airport....

There was also a build/design thread here on TRF some years ago about someone building or wanting to build one, might have even been one of our German members.

I am working on my own BT80 version of this model... 2x D12-0 engines in Booster and 1x D12-3 engine in sustainer. My model is on the right obviously, my 3D mock-up in the middle, and a photo of prototype on the left. I actually patterned my version after the one at the Udvar Hazy that I saw last month (slightly different nose cone). Finally, getting around to painting / staining and assembling mine so will post more pics once it is done. Still trying to gauge how much weight is needed in nose cone. Have this modeled in OpenRocket but need to see where CG winds up once everything is put together.

Beautiful!

Thanks and hahaha... bit over 29" tall and around 510 grams when I simulated it - it was pretty stable with 2oz in nose. Not quite as stable as most people would want with the booster but more stable with the sustainer so I think that it will be ok (launching off 6' rail).

Finishing Progress (I am painting / staining parts before assembly which I hope works):
  • Stained Fins - Check (I decided to do all same color even though the boosters look a bit lighter in most of the pictures)
  • Painted Body Tubes - Check (Finally figured out color is more terracotta than orange). Need to mask rear body tube to do dark gray band over where fins mount (I decided to just paint that difference instead of an extra 3D printed part / weight).
  • Painted 3D printed parts - Check (still need to print some of the small parts, I think I will do dark gray instead of silver since the 3D parts are not good enough to get a shiny paint job).
Here is OR simulation (maybe I should make my own thread).
