3D modeler Atherin posted his recreation of Krystal's CloudRunner, her custom Arwing with twin laser guns and a single lock on torpedo from Star Fox Command. In that game every character had a different ship with different attributes. Krystal's craft was designed to resemble the CloudRunner pterodactyl species from Sauria. Atherin's model even includes a textured cockpit and an Command-themed Krystal pilot.
Atherin has TONS of other Star Fox related models, such as the Orbital Gate from Star Fox Assault.
You can view and download the model on the 3D Warehouse Listing. The model is available as a Collada or SketchUp file.
Somehow, I only recently found out about this model, but it has apparently been online since 2013. Thanks to Wreckingcanon for letting me know about it.
