The problem woith changing the wing and such in the sim is you are now taking away the problem of wing rock and not learning to deal with it. I have taken measurements from my planes and transferred them into both G3 and Aerofly pro to get them to better emulate the real thing. This is, to me, by far the best way to do this, though it does take quite a bit of work. You wll end up with something very close to what you have in real life.

In G3, I have the Yak laid out with the exact same measurements and my 75cc Aeroworks and the Cap has been downsized to my GP Cap232. Both fly as close to the real thing, not totally but very close
