No nitro driver should be without one!

The Turnigy Micro Failsafe is designed to return the throttle servo to a preset position in the event of a signal loss or if your reciever battery voltage drops below 4.2v. The unit fits in-line between your throttle servo and the reciever and allows you to programme the amount of brake you need in order to stop your car safely in the case of either a signal loss or RX voltage drop, a great safety device!
