Fail-Safe

The buggy has a fail-safe built into the receiver.

What a fail-safe does is in the event of the buggy losing signal from the transmitter is to move the servo to the brake/neutral position (user to set up).

This however relies on battery power. So, if your battery goes flat or your servo fails, it will not work. This means it has multiple points of failure meaning it is not a sure way to stop your car from losing control. Your best option is to purchase a kill switch and not rely on the Radio Failsafe.
