hmm. lets see, if i remember correctly one of our neighboring teams (173) threw the chips onto their drive train (which used the drills) at the last second to help them turn better. I'm not sure exactly what reduction they used, though I'm pretty sure that they ran the chips at in and around 30% voltage. that being said, their high speed was about 12 ft/sec - since you probably won't be going quite that fast, you would need a bigger reduction then they had in order to get the same efficiency (remember, 30% voltage is not the same as 30% power. If you want details on how they did it i suggest you send a pm over to Joel J. the period is part of the name, not the sentence)

you would have to buy some different sprockets as the ones in the kit probably won't work. i do remember seeing this robot which has the chips tied into the drills. you could send an email over to whoever posted that pic if you needed more info on how they did that.

its always worth it to give yourself more power. believe it or not, it actually takes less battery power if you have more motors. battery power drains the fastest when you are completely stalling out a motor. if you have more motors, you have more power, and are therefore much more likely to simply spin your wheels instead of stalling. you will turn faster, go faster, trip breakers less, and all in all be more manueverable and versatile if you throw in another set of motors. the the 2 or 3 pounds that you pick up by adding them is paid back tenfold by the increase in power. remeber, lightness only matters because acceleration = force/mass. if you increase the force a lot and increase the mass a little, you're still better off than where you started.
