As far as I can tell, P-factor isn't a factor in this game. Not that I mind, since I'm more concerned with higher speed handling ("Hi, I'm Lemur. And I'm a an e-fighter". "HI LEMUR")
I'm hoping that as the flight model gets tweeked further we do get to see more of the individual quirks of the planes appear.
While on paper the p-47 didn't look all that great, the men who flew it consistantly praised it as a very stable platform. Whereas folks dammed the Yak-9 as a very 'bouncy' gun platform. Be nice if these distictions made it into the model.
