This reduces the length of the drivebase effectively in half, requiring less torque for the robot to turn in place.
Also, make sure you look at all of the other issues before putting in a new transmission in the drivetrain.

Thank you for the advice! I am pretty sure that you are right, in that our center wheel is not lowered. we are meeting tonight and I will be sure to check it out and grab some pictures.
Also keep in mind that we are only going to make minor changes to our competition bot if any (no major drive train changes) like flipping the frame. In the off-season we intended to experiment with frames (among other things) that are not intended to compete. We have good programmers, tools (mills,cnc,lathe) etc... that if we were optimistic we might attempt to build one of the complex drive trains as a prototype.
