Not long ago I posted about the small amount of wing flex on most of the better A/C available for FSX but it occurred recently to me that there is no wing flex when taxing either. In real life there is a lot of wing flex while A/C taxi especially with larger A/C. Is it even possible to have wing flex while A/C taxi in FSX?

I think the PMDG 747 has wingflex during taxi.

Yes, it is possible with certain add on aircraft ie pmdg 737 NGX
