I have found a problem with running these with 12 volts. The 6 volt motors themselves have a nylon drive gear which is supported by a metal bracket that has a D shaped keyhole matching the motor shaft. This nylon gear has a tendency to pop out under the extra torque of a mechanical shock as the motor heats up. Gluing doesn't help as nothing seems to stick metal to nylon with enough shear strength. I was considering adding a small 12 volt boxer fan to cool the motors.
