Stopping

[RockiesFan05]

What are some ideas on how the buggy stops? I was thinking that a bolt could get tight and it would stop, but I don't know. Is there a certain type of motor?

If you look back on last years forum there’s several great detailed explanations of this but the most common way is using a threaded rod as your axle and have a wingnut on it. Have something hold the wing it in place in relativity to the car and as the axle turns the wingnut will move to one end, where you should have a locknut or something of the sort to stop it which will stop your car.
