Hello!
That’s wierd. In the 3D file, the wings are in the center of the world? (Not the point of origin, but the center of the geometry itself)
When you import a 3D asset to Unreal, always puts the center of the object at 0,0,0 of the 3D space in the file.
Then, for example, in this Blender Scene (This applies to every 3D program) the center of the object is in the red circle, but if I export as a .fbx and import to Unreal, it will give the point of origin to the blue point.
Let me know if this helps you!
