On four engined aircraft the outboard nacelles are very low to the ground and don’t tolerate a large roll angle.
Usually in FSX/P3D you get an awful scraping noise if you are touching the ground with anything but the gear.
If the PMDG 747 doesn’t crash and doesn’t create a scraping noise than the MSFS version can be indeed considered more realistic in this area.
I’ll experiment with the contact point on thte 747 today and let you know.
edit: just checked the RW manual and the roll angle limit is 7.5°.
