Thanks. But with my logic, heavier side gets less traction. So I just don't get the explanation that having the motor in the rear gives more rear traction. For example, if you move both the front and rear wheels forward keeping the same wheelbase, the rear becomes heavier and the car gets more steering meaning less traction in the rear.
With that said, if I compare ONLY the weight distribution between MM and RM, MM gets more rear traction than RM due to the lighter rear weight meaning MM may understeer. Again this is only hypothetical on the condition that everything else is same between RM and MM. But I see there's quite a difference between RM and MM's configurations. Whatever advantage/disadvantage each car has, I'm pretty sure the Serpent engineers compensated it by making a few changes between them.
I just don't see the huge advantage of MM setup so far and thought it might be trickier(less/more responsive to setup changes) to set up than traditional RM design. and I was hoping somebody would fill me in. Thanks guys.
