This is a more recent example of how my model is developing. At this point its hard to stop my computer from slowing down big time, so its a slow process. let me know what you think

This is the tank with my new tracks. hope you can spot the difference compared to the last video.

This is one experimental video I have not yet deleted, where i worked on the motion of one wheel in relativety to the motion on the tracks. to do this effectively i wired and linked rotation parameters of all the wheels to one master wheel. in this way, only the master wheel need be animated, in order for the full track system to follow in syncronisation.
