Can't disable gravity for skeletal mesh

This has stumbled me a bit. I started off with the Flying UFO template. It has disabled gravity and use C++ code to move the ship around. Works great, except it doesn’t really handle physics and collisions.

I replaced the static mesh UFO with a skeletal mesh for bone animations of a bird flying, but it keeps falling to the ground. I’ve tried disabling gravity on the skeletal mesh, but it still falls as if gravity applies to it. If I disable physics altogether, it does not fall, but I want collision physics and Hit events. The mesh has a physics asset with a single body of about 2 kg. If I go back to the UFO static mesh with the same settings (physics on, gravity off), it does not fall to the ground. Is this something fundamentally different for skeletal meshes? Can’t I disable gravity while still simulating physics?

Reproduced on 4.3.1 and 4.4.2.
