In an effort to get more people to fly early war planes and other planes that see little use in the main arena I think there should be a top pilot by a selected aircraft during each tour. To limit the efforts, at the beginning of each month, one little used plane would be designated as the plane in the top rank pilot contest.
This would encourage some people to fly these little used planes to try to be the toped rank pilot for that plan for that tour. Imagine being the best C.202 pilot four tour XX, or the best P-40 B, or the best Hurrican MK 1 pilot.
I think this might draw some people away from the LaLa's, the Spit's, the Nik's and the P-series planes.
