Futaba FSU-2 Fail Safe Unit FUTFSU

The Futaba FSU-2 is a compact fail-safe unit that installs between the receiver and throttle servo on RC cars, trucks and boats. It automatically returns the throttle to a pre-set position if the model loses radio signal or the receiver battery voltage drops too low, helping prevent runaways. Programming is done with a single button and status is shown via an onboard LED.
