Hi Dreher,

it is a lot of work! First you need to rotate the main wheel which is best done by the new command vec_rotateaxis (VECTOR* vDir,VECTOR* vAxis,var angle), because you can get the 12 deg off vertical easily. Next you have to rotate the satellites (black parts) at a certain relation to the main rotation. This relation of rotation speeds is fixed. And last you need to implement the cars and their inclined axis using the 3DGS Physics Functions, because they have no forced movement, they are accelerated by inertia of mass. Position of center of gravity is critical. Do not take the real mass in kg, Physics does not like mass > 60 approximately. Sorry, it is too much to just write the software for you.

Nice task
