Hmmm...its an animation issue...its P3D.
Let me see, the 767 in P3D also has animation issues, seems they are done with fixing animations in P3D for that aircraft.

The 767-400 for MSFS was released yesterday...someone already complaining about wingflex...CS answers the next day.

The 737 wingflex issue was reported in the beginning of April over 8 months ago, not a peep from CS.

See where I'm going here?
