Spitfire & Hurricane flight model & engine performance thread. (1.09 patch)

[Osprey]

What klem is referring to is what I mean JtD. IIRC the Merlin XII did not require field modification, this was already done at the factory, and the throttle was different and designed with a dog leg 'gate' in order to move from max 9lbs to emergency 12lbs. It's a slightly different system to the Spitfire I. I have "Merlin In Perspective" - it's Robo's copy and I'm getting through it slowly!
