I heard the Broussard described last week as being 2nd only to the Antonov AN2 as being the most uneconomical way of turning avgas (money) into holes in the sky (flying pleasure). Ha ha. They do look somewhat "ungainly".
I am at first blush daunted by the P51D, but I could I think overcome that with the application either of vast quantities of money or the generosity of a P51D owner... same applies to the Spitfire, Corsair, P40...
