Ive been flying the M abit this camp and it is a nice plane. I dont fly the 1a much so I cant really say much about it. Both planes do feel alot heavier when low and slow than say the P40E, but it is nice shooting planes that normally walk away from the P40. I like the roll in the M, its quicker than I thought it would be. And of course the guns are nice. Best chance of a kill awarded than any other bullet armed plane, when competing with friendly cannon birds. I dont really fly it or any of the faster planes as I should though, and I usually end up on the deck fighting a couple. Sometimes it works, sometimes it doesnt. But its fun either way, and you can make the M do some nice stuff slow(reminds me of the FM2 in rudder response).
