Well, here's a trick. Maybe if it looks too earth duckish when still, you can make it look a little more Alien in flight. There could be no legs under there and it's body can just kinda fold down into something a little more "Movie Soundwave"-esque when it's either self-supported or in ZeroG (if cybertornian wildlife can handle getting into that kinda atmosphere, I have no clue what the air is like on that planet o.O)
