Well , in real life, I have seen 7 Spitfires take off together, including Mark V, throught to Mk14
The Mark 14 absolutely dominated the earlier models in apparent performance at 0-5k.
It acceleration it clearly was far better at display routine boost levels (which I dont know what they were limiting their engines to).
It was faster, louder (hurt the ears even), and with clipped wings, low back and bubble canopy and five prop blades looked DEADLY!
