The controller for the 6ch one would probably more closely match a real RC heli TX in terms of functions. I think I have the FMS software (though it might be a little older version than what those come with) and doesn't come close to RealFlight. I mean, it works and will help you a little with basics like orientation but it's not very realistic flying so you don't really get the "feel" which is important with helis.

I think the software can be downloaded free from the fms website, all you're really paying for is the controller.
