Futaba FSU-2 Micro Fail Safe Unit for RC Vehicles  [FSU-2]

Secure Throttle Control with the Futaba FSU-2 Fail Safe Unit

For club days and weekend runs, predictable throttle behaviour keeps models safe. The Futaba FSU-2 Fail Safe Unit prevents runaway incidents in cars, trucks, and boats when signal loss or a drop in receiver battery voltage occurs. Its compact footprint makes it easy to fit into tight radio trays.

Benefits of FSU-2 for Hobbyists

The Futaba FSU-2 is built for straightforward reliability. If interference hits or battery voltage drops, the unit drives the throttle servo to a preprogrammed setting so the vehicle does not lurch away uncontrolled, protecting both your model and nearby equipment.

Fast Programming and NiCd Optimisation

Setup is handled with a single button and confirmed by a status LED, so you can dial it in quickly. It works with 4.8V and 6V NiCd receiver batteries and is optimised for the consistent discharge characteristics of NiCd cells rather than other battery types.

Adding the Futaba FSU-2 Fail Safe Unit is a sensible step for enthusiasts who want to reduce the chance of damage from lost signal or low battery events.
