This kind of depends on just what it is you want to do with it. Do you wish to learn to fly R/C aircraft? or do you want to use a joy stick type of controller and fly as if your in a real plane.

Both types of sims will give you the same kind of flight simulation, if you have it in the cockpit mode. As if you were looking out the front window. or some may have a chase view.

But if you do wish to learn R/C flying your going to need the R/C type of Sim. With a cable hook up to your transmitter.

I've got the first Microsoft Flight Sim 98... and at the time it was pretty cool. (which by the way I hear is worth good bucks because it has the Twin-Towers on it)...
Using a joy stick for a controller you can also get the wheel and pedals if you wish to really feel the ride and fly as if for real. I'm sure the newer versions are even much better.

But like I said if you wish to learn R/C flying your going to need G-3, or R/C-Flightmaster or something like them.

As far as I know you can't use a R/C controller with Microsoft Flight Sim...I may be wrong? Anyone have the answer to this? I just know I can't use it with MFS-98.

Oh-and "No I don't want to sell Microsoft Flight Sim 98"...I get tons of offers for it. I would think there are still millions of 98's around. Back then it was a very hot seller. And if your looking for that in the cockpit feel, MFS maybe the best way to go for you. But if you want to lean R/C go with something else.

I like R/C PlaneMaster myself...only because of the price for it and it did teach me to fly R/C.
But I'm sure G-3 is the better program in the R/C category, though I've never used it.

Best of luck and whichever one you get... you'll have fun I'm sure!
