I say that becoz when running at top speed, higher volt. would increase the speed, which increase the impedence of the motor, so lower the current, and thus for longer run time.
When both 3cell & 4cell car are running at the same speed, the power dissipation should be the same.
(all in all, 24mAh in 4cell must contain more power than 24mAh in 3cell)
