Thanks for the answers and discussion all
(Keep going if you'd like)
I find lowering the throttle a bit usually resolves most overheat issues and I try to manage the rest of the issues that poses tactically. I'd love some more complexity and detail in the engine modeling system but I'm not sure how much more I want to handle up front. I do like being able to jump from warbird to warbird without too much trouble. I love the simulation aspects and the realism but sometimes there can be a bit too much realism. This isn't my job... it's supposed to be a fun thing to do
But that all said... options are brilliant so settings can be what they need to be. I like the level of complexity we're currently at but I'd love to see more complex modeling behind the scenes if that would have an impact on the game.
