This is a relatively old kit, so it is to be expected to have issues with the parts and the graphics. However, it is a unique model and really nice to see obscure aircraft designs ( too many Mustangs, Spitfires and Zeros models out there ). The Japanese Kyushu Shinden is very similar design.
I got to see the real plane some years ago in the Air Zoo museum in Kalamazoo Michigan

. Very interesting.
The US military joked about the airplane and really called it an "Ass Ender " due to the pusher configuration.
