The P-38J is racking up quite a kill ratio in the MA. In fact it is the highest non-perk plane in the MA.(see table below)  I did a little digging and discovered that a dozen or so pilots have kill ratios over 8:1 in this plane and fly it almost exlusively which is driving up it's kill ratio. I did this investigation because lately this historically average plane has been untouchable in 1 on 1s, and the deaths have all come via the same tactic on the part of the 38 driver, which is to pull the plane vertical, wait for the opponent to stall out, rudder/throttle over, dive and make the kill. What makes this so strange is the seemingly incredible ability of the 38 to climb vertically, and rudder over, regardless of e-state. On paper this plane has inferior power to weight, climb rate, and acceration numbers compared to most planes in the MA. Perhaps a dual throttle control can allow for rapid yaw compared to centerline powered aircraft that need to rely on rudder only (hence airspeed), but that doesn't explain the 38's seemingly exeptional vertical climb and stall performance. I suspect a cabal of 38 drivers have discovered something about the P-38 flight model that can be exploited in the MA and are utilizing it to rack up these lopsided kill ratios. We non-38 drivers owe it to ourselves to figure out what's up. I  would like to analyze this 38 manuever more objectively, and get the word out to all MA pilots the what-to-do's when a 38 pilots goes vertical. With a little collective wisdom maybe we can put these guys back in their historical place. 
So I'm asking for anyone that wishes to participate, to film your missions and post any 38-goes-vertical-rudders-over-and-kills-me films you get. Then we can analyze e-state, relative speeds etc etc and see what's up.
I don't mean to over emphasize the idea of some kind of flight model error. The real point of this post is to understand the tactic objectively to develop a counter.

no. you did the investigation, because you lost a fight or 5 to a b-38 that you didn't think you should;ve lost. i'd guess that you mis-judged the 38's e-state, and tried to follow him up(most likely in a spit of some mark, or a hurri2), stalled, and he kilt ya as you wallowed in the stall, flopping around like a fish outta water. 
 anyway......you are also wrong on all of the 38's kills coming from this tactic. even me, with my inferior skills in the 38, can score kills without having to rope someone. 
 you'll also find that generally, there's 2 kinds of pile-its in the 38. those that can fly her amazingly well, and those that can't fly her in combat at all. you can tell the difference by the end of the very first turn in the fight. 
 the 38 was an amazing aircraft in its time. it was fast, maneuverable, had excellent range. 
 power to weight? think about the second part there.
