thanks for the quick comments guys.

So a couple fo things: this is a side project bot, which will have the function of a corner goal scorer. We're trying to build it so it could compete, just for the sake of practice. My idea to use all of these motors comes from the fact that we would only need window motors for our ball gathering and expelling system, thus we would not be contstricting other areas of the bot.

With the wheels that we are going to have made, (they're the same as the ones on our bot now) we have never had our wheels spin in a match. Their traction is so high that the extra tourque qould go straight into pushing another bot.

Also, ignoring the power issues, would the extra tourque be worth the weight? Or would it be one of those really-cool-but-never-used mechanisms?
