You're not really helping the case here. I've asked you to help out. Jan, whom you are referring to, also agreed with my followup post on lack of wing flex. A wing will naturally have some sort of flex. That flex is POINTLESS to model if it can essentially not be easily seen. So, again, I ask you to please find us a video of a 737-300 showing the amount of wing flex you're looking to have modeled. I couldn't find any on YouTube. Plenty of 737-300 wing videos out there, just none with flex, even in turbulence, so I'm asking you to now help out in understanding what you feel is worth modeling from a real video of the real aircraft which you find.
