DeviantArt user SAB64 has made a fully rigged Arwing mesh for Miku Miku Dance. The cockpit canopy opens and closes, the wings can be adjusted, and the guns can be revealed or hidden. This mesh came from Star Fox Guard, so it looks like the one used in Star Fox Zero. Download it on the info page. It's a nice Arwing if you want to make simple Star Fox animations in MMD.
There is also a Fox McCloud Rig available.
