I'm currently building one, and a Minimag to go with it, the same as in the RCDON build log referred to by MichaelR above. I'm about 9/10 of the way through both builds. I picked up my set of castings at the factory when I was in the USA last year, and started machining them about last Christmas. Not very fast working, but my main project is getting my steam launch finished.
I'd be happy to discuss the Red Wing. The casting are all of excellent quality and I am very pleased with it.
