It's the ONLY thing I've ever spent this much money on and never had guilt feelings about or any regrets. I use it daily. I'm now exploring park flyers so all I have to do is adjust the existing aircraft to the appropriate sizes and change to electric power systems. I can then fine tune from there to see how different prop sizes/gearbox ratios etc affect flight performance.

I have tried FMS also and it's a good thing it's free. I seems more like a bargain bin computer game than a simulator to me.
You will not be sorry for getting Real Flight G2 unless the wife finds out you spent that much money.
