As with the Arwing and Fox McCloud rigs, SAB64 has made more Star Fox models available for use in MMD. There's the Fully Rigged Falco model from Brawl, and the Landmaster Rig which has animations for the treads and wheels. I presume it also has bones for other movements, such as adjusting the cannon. The Landmaster Rig is also a modified version of the Landmaster found in Super Smash Bros Brawl. Downloads for both of them are found on the gallery pages.
