Ron,

Even the cheap FMS Simulator is great, I'm sure the more expensive ones are better but I've learnt most 3D on FMS which was £17 with a TX and the just found sites to download 3D planes like the E-flight Mini Funtana Min Edge and the Seb Art Katana all of which are quite realistic.
That said I can't be that good as I destroyed my Acromaster which I've learnt 3D on in the last year yesterday morning prop hanging it and it came back over the top on me and I couldn't recover it []
