For anyone with experience with the old style Drone Remotes, there's this piece in the box I cannot make sense of and I could use some help with it. It's just a single piece in each box and it doesn't seem to correspond to any of the promotional photos. It's not a head, arm, wing or tendril. It's a fairly big piece, about half the size of the body, with a concave part that slots in pretty well to where the head goes. Does anyone know what the heck it is?
