Sorry, I'm not much on single yes or no answers

No.
Granted, that is fun to do, and I run the ms Flight Sim 04 often, but that's when I want the realism.
Every time I sit on the runway fiddling with the engine controls I imagine what it would be like with a dozen vulchers over my head and it doesn't sound pleasant.
Mostly though, this is a business venture for Hitech, and "most" people in here are not set up with controls to adequately benefit from those complex settings. The market would dry up and the game would have the population of say, a warbirds or something. How does 49 people in the most popular MA sound? Compare to the fact that we had over 800 people in the game mid week last week. (Ya, I was in WB last night, 49 people total)
You could turn it off or on, but then you have players who are Not using it running over the top of those who Are using it, simply because they don't have as much to think about while shooting you as you adjust your engine mixture. Then there would be another massive debate started because the full realism users were getting killed all the time and it isn't fun, so they need to Force the other guys to play with all the knobs and buttons..yada yada..
The effort to recode the entire game to bring this system online would take away from improving the already popular game in front of us, for the sake of a Few people who would actually use it. Doesn't make sense.
Fun? Ya, sure it is. Reasonable to introduce here? Not hardly. Heck, we can already adjust the trim, the rpms etc. The Flight Model is good. At some point, though, you quit playing the game and just fly the plane.
Oh, did I say "No" ?
