About 10-12 years ago there was a sport jet from Germany, called Jurassic. I have done some small modifications to it, and tried to cad it, making it suitable for laser cutting. A friend of mine started building the prototype, but then he suddenly could afford ARF jets ;-)
It was made for 100-120N engines, but could probably be scaled down a bit.
