Below is the World Models .40 size P-51. I bought this as an ARC. You do not save much money but the door is open on covering. It is a very good sport scale. The scoop is a bit off but easily transformable. it is a good plane. If you want to keep the nose area intact. Throw a 100ish fourstroke inverted to solve that. I have a ST 90 sideways on this.
