Don't normally partake in the "Perk the (fill in the blank)" discussions, but looking at the K/D on Innominate's page, I noticed something interesting:
Model      Kills      Deaths      Kill%      Death%      K/DRatio 
Me 262   1129    149           0.62       0.08            7.53 
Tiger I     4686    932           2.57       0.51            5.02 
Tempest  405     103           0.22       0.06           3.89 
Me 163B  300      87            0.16        0.05          3.41 
F4U-4      319      97            0.18       0.05            3.26 
F4U-1C   2899   1045          1.59       0.57            2.77  
Ostwind  9259   3950         5.09       2.17            2.34 
Ta 152H  269     126            0.15      0.07            2.12 
Out of all the vehicles with a K/D greater than 2, the Osty is the only one that isn't a perk ride.  Just food for thought...
