Futaba FSU-2 Micro Fail Safe Unit for Off-Road and On-Road  [FSU-2]

Keep Your RC Under Control with the Futaba FSU-2 Fail Safe Unit

When conditions get unpredictable, control is essential. The Futaba FSU-2 Fail Safe Unit helps protect your RC cars, trucks, and boats by preventing uncontrolled movement if the signal drops or receiver voltage falls. Its compact design fits neatly into most setups and reduces the risk of costly damage.

How the FSU-2 Protects Your Runs

The unit is made for pilots and drivers who expect consistent behavior. If interference or a battery dip occurs, the Futaba FSU-2 moves the throttle servo back to a stored position so the model does not accelerate unexpectedly, making recovery easier and limiting potential crashes.

Setup Simplicity and NiCd Focus

With simple single-button programming and a clear LED indicator, the FSU-2 is straightforward to configure. It is compatible with 4.8V and 6V NiCd receiver batteries and is optimised for NiCd cells because of their steady discharge profile compared with other cell types.

The Futaba FSU-2 Fail Safe Unit is a practical safeguard for any hobbyist who wants predictable throttle behaviour and fewer surprises on the track or in the paddock.
