Basic requirements are - well - same as an RV-9: Metal, 2-seat (not
tandem), power from O-200/O-235/IO-240/O-320 - minimum cruise around
150-175mph, range approximately 500-600 NM+, very stable
(non-aerobatic)

Apart from the "Metal" requirement, you've described the Vision
plans-built. (It's composite.) See http://www.visionaircraft.com
