I don't know about all of you, but when i look at the design's for gearboxes and transmissions in the white pages and what i seen at nats last year, i seen a WHOLE lot of metal! That has to be a huge amount of weight to slap on a drivetrain! To maybe loose a little acceleration you could use a simple geared down (or up) shaft with a cupling and sprocket. Even if you wanted added torque, simply meshing in another motor wouldn't add up to the weight of a transmission. Keep in mind that a few ounces off a drive system is another few ounces available towards a mechanism.
Now i take this position on this subject because of last years game. We have a very muscular drive system on EL TORO, a VERY VERY muscular one that took up every ounce of weight available. Now, dopn't get me wrong the extra power was outstanding and we could push anything we tried, but as a result of the robustness we had no room left for a claw to get the goal. The reason for the power in the drive train was to push two goals. Now we over estimated the resistance in moving two goals at a time so by the time we finished the bot and tested it on a goal we realized how we didn't need even close to the amount of power we established.

POINT-- I would use the extra weight for a more practical use in the game.
