Short description of error

I can't export properly the animation using FBX binary 7.4, I've tried to use different settings and none works.

Exact steps for others to reproduce the error

When exporting to unreal 4, there's some units difference with blender. I deal with this by changing the units to metric and setting scale to 0.02, I've also tried changing the scale in the export options to 100, as recommended in this video: https://www.youtube.com/watch?v=Ayp1lof0RJU .

There's a difference between the way the animations and the reference pose are exported, sometimes the reference pose is way bigger than the animations and sometimes is rotated 180º. Besides, the animations are always exported wrong. When I export to ue4, the log says that imported bone transform is different from original.

This is how it looks in blender (rendered):

And this is how it looks in ue4, look at the wing and legs, they should be in front of the body, like the rendered version:

This is the reference pose, that is, the mesh without any loaded animation, it's orientation is different (rotated 180º)

I've been able to export these animations properly using ASCII 6.1. But as far as I know binary 7.4 will become the rule and ASCII 6.1 is outdated.
These are the last export options I used for 7.4

And these are the export settings for ASCII 6.1 that exported the animations properly: I have to note that I had to tweak the orientation inside ue4, but the animations were just fine.

This is the blend file and the texture so you can try:

duck.blend
