Mustangs are great flyers but most people seem to like others as a first warbird. I'm slowly working on a TF P-47 an it is a great kit.

As for ARF's, I have the Top-Flite 60 size Mustang ARF and it is a gorgeous, well-built, great flying airplane. They also just came out with an AT-6. I like the H-9 Sptifire too.
