A fully loaded Spit XIV of production line will climb to 20K in 5 minutes smooth. In AH it takes close to 6 minutes, so the XIV is porked in that way.

I highly recomend it although I haven't taken the time to read a whole lot in it yet, very interesting but also very long, over 600 pages of pure facts.
Karnak, maybe you can help, which spit 14 do we have? F or Fr or non of those two? The "E" had clipped wings, right?
