737 sim
Thanks for your comments, RVF. I'm not familiar with the initials in your first sentence but am aware that there are better models. A friend really into FliSim, (he's just bought a Virtual Reality headset,) has recommended the Zibo Mod which I had a crack at last year on a very sophisticated setup elsewhere.
However, I have no idea of how accurately it models a real 737 so I have to rely on those who fly it for real. My last and only fixed-wing flying was fifty-five years ago in a Chipmunk.
Thanks for the info about the 737 trim. I do enjoy flying it (recently Taiwan to Hong Kong) but find it most satisfying to try and fly it as realistically as possible. Which is where I came in.
