A Failsafe is a device that will save your car if it goes out of range or the car batteries run out. you hook it up to the receiver and you can set it so that the throttle servo automaticly brakes or just goes to idle position if you drive it out of range or run out of batteries. Before i got the failsafe I forgot to turn on the TX once, started the car and it went flying on full throttle with no steering Luckily it hit a jump and landed in neighbours hedge with no damage except the air filter came off and engine stopped running.. Always remember to turn your TX on first! or get a failsafe
