737 desktop sim question
A question for those who know 737 well please. I'm a home simulator enthusiast, my sim of choice is the Zibo mod 737-800 for xplane11. My question is about the pitch trim. I get the aircraft nicely configured on the approach, flap 15 gear down, usually around 150 kts. When i select flap 30 and slow to landing speed i have to put what seems like a huge amount of trim in to keep the nose up. Is this normal for the 737 or a glitch with the sim? Many thanks in advance.
