The Ki 61 Is a good plane for that. It has a nice strait tapered wing with an aspect ratio of 6.61 which would be nice for racing. (Aspect ratos of 7 to 9 are best for racing, but generally not possable in scale unless you exagerate. I pesonally don't like to ruin the scale outlines.) The ta 152 I'm working on has an aspect ratio of 8.3.
