Even with 4 motors, it'll be difficult to get a usable top speed once it's geared down all the way. Furthermore, a second gear with a higher top speed for this would probably create a useless power well, and would have to be tested for optimization (calculus would come into play and simplify things here, but considering that only about 10% of my school takes a beginning calculus course, it's out of the question). Last, the normal two-speed shifters are simply too expensive for us, and would also require pneumatics, something we've began to abhore due to it's weight and volume requirements.
