Protect Your Models with the Futaba FSU-2 Fail Safe Unit

In competitive and backyard sessions alike, reliability matters as much as speed. The Futaba FSU-2 Fail Safe Unit acts as a safeguard for your RC cars, trucks, and boats by preventing uncontrolled movement when interference occurs or receiver battery voltage drops. This small unit helps you keep control when things go wrong.

Why the FSU-2 Is a Smart Addition for Racers

Built for hobbyists who want predictable behaviour, the Futaba FSU-2 steps in if you lose signal or the battery sags. Instead of the vehicle surging or running away, the unit returns the throttle servo to a saved neutral or low-throttle position so your model remains manageable and easier to recover.

Easy Setup and Battery Compatibility

Programming the FSU-2 uses a single button with a clear status LED, making setup quick before a race day. It pairs with standard 4.8V and 6V NiCd receiver batteries and is optimised for NiCd chemistry because of the way those cells discharge compared with other types.

Specifications

  • Length: 0.85" (21.5mm)
  • Width: 0.6" (15.5mm)
  • Height: 0.3" (7.5mm)
  • Weight: 0.18oz (5g)

For serious hobbyists who want an extra layer of protection during practice and events, the Futaba FSU-2 Fail Safe Unit is a compact, dependable tool to reduce crash risk and protect pricey models.

Any RC car, truck, or boat that uses a 4.8V or 6V NiCd receiver battery can use the FSU-2 when wired to the throttle channel.
NiCd batteries have a predictable discharge curve that the FSU-2 expects; other chemistries can drop voltage differently and may not trigger the unit as intended.
Yes, the FSU-2 records a preprogrammed throttle position during setup so your servo returns to that saved point if a fail situation occurs.
Setup is typically a matter of seconds using the one-button method and confirming with the status LED, making it quick to adjust between runs.
