Some news:
I'm slowly positioning and exporting crew meshes for use inside craft (there are at least 2 models for interior for each crew members ). Crew will be fully configurable with variable set of meshes (for example you can have crew member with laptop etc.)
Also there will be Crew SDK so users could model new meshes (seat and controls template will be provided in msh, obj and 3ds format).
RCS is coded, and doug is currently working on flightmodel.
XR3 Phoenix 3dmodel in its current state is available on turbosquid is someone wants it, or want to support developement (not mandatory).
