Recently picked up FSX (it's cheap now) and been playing with it a bit for a few weeks. I like the graphics, and virtual interactive cockpit controls, and that you can use ATC, and GPS and VOR and ADF and all that. And I love that it has pretty much every airfield in the world with it.
But one thing bugs me about the flight model (maybe the whole thing is off I don't have the experience to tell). It seems impossible to really stall, or spin some of the planes.

I just spent 20 minutes with the FSX Cessna 172 trying to do some spins, it just won't do it. (and I KNOW a real 172 isn't that hard to spin.) At stall the nose just mushes over and pretty much instantly recovers. Even at step bank angles with completely uncoordinated turns it just mushes into a vertical yaw and pretty much recovers itself. Basically it seems that both wings stall at the same time no matter what you do.
Is this a problem with FSX in general or just with their 172 model? You'd think being the most popular small plane in the world they could get the flight characteristics right.
Any other sims out there with massive detailed interactive world, and lots of planes like FSX, but with better flight model. I've heard of X-plane but don't know much about it.
PS. I'm gonna go play with the FSX Mooney, Baron and Maule models and see if it's the same with them. Although I have no real world experience to compare to with them.
