give it two equally skilled, fairly good but nothing special pilots, the g2 will win every duel.
now let two monsters fly in them, the g6's chances increasing dramatically.
why?
the extra weight is all in the nose, ruining the g2's good balance and make the aircraft nose-heavy. And oddly enough, it dont hurt the turn rate as much (2-3%) as it increases the stability in ultra low speed vertical reversals. And thats definiately the move the top 109 sticks tend to use.
For the same reason, i "feel" the k4 better than my little beast.
