With 8" wheels, people aren't quite taking into account sudden shocks that can be imposed on gears with the torque of 2-3 CIMs in a gearbox. Start doing some Lewis Gear equations and use a decent factor of safety. Vex gearboxes weren't meant to do certain things, and as a designer, you need to determine whether the gearboxes can handle the loads you're putting them through. If they can't, you have two choices: find another gearbox or modify the COTS gearbox to make it work.
