Righto, I've been flying for hours today in P51D-20 against FW190s and me109s and I'm now certain that the AI is a cheating bastard. No matter the skill, average, veteran & ace all outclimbed my P51 from positions like they flying level at 1000m, I diving down from 3500, having speed of 820km/h when starting the climb. They usually dont climb faster than me, but they can keep the climb going longer than me. Pretty nice, taking that they were flying ~400-450km/h against my 820km/h.
