Spektrum S681 25T Brass Gear Servo 1/10 ARRMA Fury 223S SPMS681

The Spektrum S681 is a standard-size analogue high-torque brass gear servo for 1/10 surface RC vehicles, suited to replacing the steering servo in the ARRMA Fury 223S BLX and other compatible 25T servo applications.

This servo provides a practical replacement option for drivers needing a durable steering servo with brass gears, 25T output spline and 6V to 8.4V operation. The standard 40 x 20 x 40mm case size makes it suitable for many compatible 1/10 RC cars where the mounting dimensions, spline count and servo horn fitment match.

FAQ

What vehicle is the Spektrum S681 servo made for? The Spektrum S681 servo is listed as a replacement for the ARRMA Fury 223S BLX 1/10 2WD short course truck and can suit other compatible 1/10 surface vehicles.

What spline does the Spektrum S681 use? The Spektrum S681 uses a 25T output spline, so it should be matched with a compatible 25T servo horn or servo saver.

Is this a digital servo? No. Retailer specifications list the Spektrum S681 as an analogue servo.

Are servo horns or screws included? The listed package contents include the S681 servo only, so OZRC recommends checking whether you need a suitable servo horn, screws or servo saver before installation.

Important Notes

• Check your vehicle manual before ordering to confirm SPMS681 is the correct replacement servo.
• Confirm servo dimensions, 25T spline fitment, servo horn type and BEC voltage before installation.
• Use a suitable 25T servo horn or servo saver for your vehicle.
• Do not force steering past its mechanical end points, as this can damage the servo gears or electronics.
• Set steering end points after installation where your transmitter allows adjustment.
• Servo horn, mounting screws, servo saver, receiver, ESC, tools and RC vehicle are not included unless shown separately.
