In addition you can swap to a 13 tooth pinion instead of a 14 tooth pinion to get additional torque. I made these recommendations to another team this season.

13 Tooth Pinions: Switch to 13 Tooth pinion gears $8 each, $32 total. Slows down your drive train but gives you more power for climbing, etc, makes your robot more controllable. http://www.vexrobotics.com/vexpro/mo...tor-gears.html

Reduce 2nd Stage: If you are using 8” wheels, Switch the 2nd stage of your drivetrain to 14 to 50. You could also use the VEXpro 14 tooth ⅜ hex gear and the 50 tooth ½” hex gear but you would need to mess around with spacing inside the gearbox. $42 Total
