Worlds Fastest RC Car Challenge take 2.

My trucks were always faster with a center differential. Not sure why

I think this is the result of the pancakes that are created in the front vs the smaller wheels in the rear (without a centerdiff) becase the tires are rather soft, the front wheels are bigger than the rear wheels when driving fast/accelerating. this results in more stress in the drivetrain, since the wheels need to spin at the same speed. (they are mechanically connected) the centerdiff cures this problem.
