I was poking across the web one day, and ran across a picture of the S. Korean Hsuing Feng 3 surface-air missile. I thought this might be a good build, esp. if I can make the ducts work. Not actually function as a ram jet, just flow air...
So I started with a basic 4FNC:
then cut some vents for the air to exit (no centering ring ar aft end of rocket)
there's a ring of card stock inside the aft section of body tube to stiffen it
And then I made the ducts, forming them over a nice piece of bubinga I just happened to have laying around
this was a fairly complicated build, the angled portion needed some reinforcement to make the joint easier to put together
Next time, I glue the ducts on!
