Imported mesh flipping bones

Development Character & Animation
1

Hi, I imported a model from 3DS MAX to UE4 as Skeletal Mesh and at first glance it appeared to be ok but later I discovered that any time I tried to rotate a bone (any bone ) the model flipped like if he’s trying to do a handstand. I tried to change up-axis in FBX export settings, I tried to change rotation on import settings in UE4 and I visited tons of threads looking for a solution but now i’m stuck. I hope someone can help me with this.

Imported model seems ok right?:

But that’s what happen when I move a bone (and I suppose it would flip when playing animations too)

Here you can download the model and take a look:
