What is the gear marked 2.5 /5.0 that comes with the Motor kit ?

burning out a motor.
Is there more to it that this ?

| It's a clutch gear. You can use it instead of a pair of pulleys with a rubber band if you want to avoid stalling your motor if something jams. Compared to the pulleys, it gives you a very well defined stall torque - it's actually printed on the (...) (25 years ago, 14-Sep-99, to lugnet.robotics)
