Haven't heard anything lately and frankly, the project looks like a wet dream. Do some research and I think you'll come to the conclusion that the claims of that aircraft just aren't attainable at the specs they claim. As for the engine...same thing. I really would love to see them succeed for the prices they claim, but not sure it's going to happen. I wouldn't hold my breath waiting around on the powerplant to finish a plane.
