What are good settings for aerobatics? I've been using 90% RPM, 7.5 [units of pressure] at 2000', both cooling things fully open, and maximum pressure and minimum temperature in the mission editor. Each flight lasts ~16 minutes before the engine quits (not seizes), but I got up to 25 minutes just by lowering the RPM and not the power setting.
I guess what I'm asking is, what's an intuitive relationship between RPM, performance, and engine longevity? In the Bf 109 module, low RPMs are much worse for the engine but the same approach (max RPM, manifold pressure below some threshold) doesn't seem to apply to this engine, whether due to general design (inline, radial, air-cooled vs. water cooling) or whatever.
