Yeah, same idea with us. We had six motors working together beautifully at one speed. We were faster than average and far more powerful than average. That is the Hexadrive(tm) in action.
With six motors producing 2 horsepower, making a tranny would weigh us down and take up so much space that it wouldn't be feasible. In any case, with the mad traction we were getting off our wheels and off the weight of two goals, combined with our superior power, our strategy really didn't call for a tranny. That's why I'd argue that your strategy defines what kind of gearbox is needed.
