Voltage gains vs weight = run time?

He would be better off with the one pack. It can cert provide the power for that setup, so its just ballast at that point. Run 1 and swap later.

The only reason I would even consider running 4S is to participate in a sanctioned race. I can only guess why 4S became a standard for 1/8th scale racing but the reasoning that if a 10th scale vehicle uses 2S then 1/8th scale vehicles should use 4S doesn't jive. This is because the needed power to propel an object increases exponentially when you introduce additional mass. So, a vehicle with twice as much mass should take more than twice the power to achieve the same speed as a vehice that is half the size. 1/8th scale racing should allow 6S-8S setups.

Is there a sanctioning body putting rules for 1/8 scale racing or is it the clubs like Dirt Runners here in NJ who has put this rule because they use it with their 1/10 scale?
