I've never seen or heard of any plastic models (injected or otherwise). There are some Phillipine mahagony solid wood models out there. Van used to sell them; might still. There are also some flying RV models out there in the radio control world. I've got one of an RV-4, made by Great Planes. I know someone who carved out some wood parts from Van's 3 view plans drawing and was able to put together a decent model for pretty much the same use you're thinking of . Good luck.
