we're using direct-drive (spur gears) instead of chain or pulleys to transfer power from the motors to the wheels of our bot

y do that the weight must be a killer. It really eats up your weight limit quickly? im not seeing the benefit of that.

actually, in the begining, we weighed about 78 lbs, but after some lightening holes in the gears, turning down the hubs, and replacting many steel parts with aluminum, we dropped almost 15 pounds. we didn't want to deal with the loss of effciency and other problems that chain drives can have if they aren't designed properly. we actually modeled our drivetrain after team 25, so we aren't the only ones to do this.

yea i can understand that 25 had an sweet drive train last year i cant watie to see what they did this year.
