First of all, this is the kind of answer I was looking for, so thak you. Also, Having a better understanding of the differences between sim and real is important to me.
My understanding of adverse yaw is superficial at best, though I will have some time on my hands to get into the FAA book. I'm not in the US but I'm sure it applies around the world.
So, as per your experience, can I get better realism with addon aircraft? Regarding flight behaviour I mean, I don't really care about looks. If so, any suggestion for GA/trainer aircraft?
Also, some think X11 is better in this regard. Is that true? I'm sticking to FSX anyway for the time being, but I'm curious what people who actually fly have to say.
