The P39 is a great fighter and a fun aircraft to fly. Not many people fly it though... I'm not sure why. Then again, a comparatively small amount of people fly the Yak compared to the La5/7, Spit, 51, 109 etc even though its close in performance. On the couple occasions I took it up in the DA I did really well with it. Not to mention it fills tons of scenario gaps, in both the American and Soviet sets.
