Importing Animation from Blender

I created an animation using only rotations in Blender, it works fine on the original model, even after Import, but when I try to apply it to another model with the same bone structure I get a position offsets. It seems like not only the Rotations where imported, but position information as well.

Try to change rig to T-pose in Unity. Or other option. When I have problem with import animations and rigs sometimes this change is working for me.
