Blowing fuses/tuning drive train

[DougHogg]

Hi,

Our rookie team implemented a gear shift for the drill motors, but in high gear, we blow fuses unless we are going pretty well straight. After watching Rage at the Nationals, zooming around getting balls, we have ambitions of being able to drive in high gear. (We also pick up balls.) Can anyone give us some tips on tuning our drive train? Any other ideas?

We have 12 teeth gears on the motors and 60 teeth gears on the wheels. Our gear shift uses a single servo to switch both motors.

I saw a message somewhere about using a can of coolant to cool things down. Does anyone else have experience with that?

Thanks for any help you can give us. (We are going to the Southern California Region Summer Classic on June 29th.)
