Who cares how it flys or if it flys? Buy it as a static model for gosh sakes. I hear that you can't buy one unless your last name ends in a vowel though. If you buy it it needs a Brodak polished aluminum spinner - I'm serious! Note the spinner on the full scale Italin-American Red.
Edit: No, forget the Brodak spinner, it's a beautifully made spinner but too pointy for a P-51. You'll have to shop. But NOT yellow.
