Yeah, I understand the physics, I was just making sure I was on the same page as you. ;) Although, your last paragraph I hadn't considered in the sense that the more efficient and less power the tail rotor uses, the more is available for the main rotor; I mean I've known that, but I didn't think about it. I also hadn't considered the "sideward" flying part of the envelope.


I develop aircraft for flight simulator and work on mainly the flight dynamics, although I haven't worked on a helo. But I definitely get the relationship between the engine and how the thrust is actually generated as a lot of people get that wrong in FS. That's why I am always looking for good engine decks, which are damn near impossible to find. Because, it doesn't matter how much you know about the aircraft's flight dynamics/aerodynamics if the engine/propulsive modeling is incorrect. In that sense, I've worked a lot with trying to get propeller aero/thrust correct. It would be the same with a helo model, I would start with the engine and then the rotor aero/thrust, because if you don't get that right, you'll never get the right combo of performance for the given lift/drag, etc. Although, the FS standard Helo flight modeling isn't the best, my understanding is that the Dodo Sim 206 is very realistic, because of how well they were able to model the flight dynamics and systems.
