I have not seen very much on this plane. It appears to be a scale up of the very popular 1974 design Dirty Birdy. This plane was designed for the pattern routines of that time which required limited knife edge ability and it flew fast with sweep wings and little fuse area. It would make a great sport plane but I have doubts that it could be competitive in modern pattern where one needs a slow wide body design with good knife edge flight capability.
