Spitfire Mk Ia 100oct performance tests - Patch 1.07.18301

[Robo.]

Great job Felipe, I confirm all the issues you mentioned including engine being too fragile (= destroyed well within temperature limits), magical cooling abilities, weird Auto Lean mixture issue and especially wrong boost reading. It's a very difficult plane to use.

I can't see why is it necessary to fly at Auto Lean when you want to use the Boost Cut-Out Override and obtain +12lbs manifold pressure. That it self does not make any sense at all. The highest rpm you can get while flying at Auto Rich is 2600, anything above and your engine starts shaking. Strange overheating issues and unrealistic time limits on climb settings as well ass BCC-O are very strange also.

I wonder if the +9lbs is just a cosmetic issue (wrong gauge reading due to wrong calibration) or the Merlin III in fact flies at +9lbs. boost. I don't know. I really hope this will be addressed in the final version of the patch + they put the mixture lever correct way around at least.

As for the actual speeds, my testing completely confirms what is stated including 2800rpm being optimal for speed at BCC-O (what is called WEP in your pdf). My reading was something like 285mph IAS on the deck. I also noticed nice climb speed between 8000 and some 11000 ft. FTH with the BCC-O seems to be 12000ft. That much is about right.

Thank you very much indeed for your time!
