Lack of enough power for all the wheels. I added a few more generators to the rover and now it drives straight. :|

Thanks for the suggestions. - Adding SAS had no effect - Adding a lot of struts had no effect - Adding weight had no effect. I noticed this only happens while accelerating, if I just let it roll, it goes straight. If I let it roll down a hill and accelerate on it's own, it goes straight. So I think that means a frame flex problem or traction. (stress/flex points that turn red would be a cool tool to find where problems are)

I've made several variations of this type of rover and all of them do not drive straight, they either pull to the left or right. All the parts "snapped" into place so everything should be symmetrical and the all the wheels should be contacting the ground the same. I've tried just four wheels on this frame and it still happens. Is this normal, or something with this type of design? Thanks.

Someday I would like a little room in the VAB that has a computer where I can run simulations. For starters, something simple like seeing my staging setup in action on a little wireframe rocket. Later I would like to be able to plan my entire mission to Eve using this simulator, then download my mission program to a chip that I plug in to my rocket.
