That is what I am noticing. The lower gear ratios, keep your tank mobile even with Multiple hits. The mechanical advantage obtained by the lower gear ratio allows tank movement until destruction. The current draw is less, and this added to the high amp batteries means you have lots of power on tap for the longest battles. Rolling resistance is suddenly shuffled to the back burner, as you just simply overcome it with gearing and amp power.

Just my opinion and observations.

But of course this is only addressing the functionality of the tank. I still fully understand and appreciate why people put time and effort into a mechanical marvel. It is a lot of fun, building something bullet proof!!!!!.
