However, the XIV will out-turn the K-4. It also holds E very well, and it can do vertical like a champ.
They are very similar in the vertical, and while the 14 does indeed turn better than the K4, the difference is not big enough to offset the very "wobbly" handling (similar to the unperked Ta 152)
During 2007, the Spit XIV managed to get only a total K/D of 0.88 vs the 109K4. That's horrible, especially when considering it's perked status prevents excessive usage by new / "unskilled" players.
And the Spit 14 did not perform much better vs the rest of the planeset either...
