I know that a sim plane will not fly exactly like the real one, but I noticed that they tend to drop their noses much more in a sim during a turn.
I am learning to fly real RC models with an Avistar. In the sim. It does tend to drop a little bit on turns, but on the sim, it's much more.
In fact, all the planes in my sim do the same. I have tried to trim them and they do fly straight. But even on smooth turns half throttle, they want to go down real fast.
What could be the cause?

Thanks,
