Pwnage, Team 2451, 10X 775Pro Drivetrain Gearbox
We ended up only needing 4X 775Pros on each gearbox to power the robot to 3-CIM levels. The weight shown was for 5X motors and power leads. The actual weight is closer to 5.5 lbs per gearbox with 4X 775pros per side. It was too scary of an idea for some to contemplate at first, but it has been a big success, so far.
