Spektrum SPMS652 S652 18Kg Steel Gear Servo

The Spektrum S652 is a standard-size digital steering servo with a full steel gear train, built for the loads that large-scale, high-power surface vehicles put through the steering system. It is the factory-installed replacement servo for the ARRMA 6S BLX family, and its steel gears are what let it survive the massive steering forces of 1/7 and 1/8 scale platforms at speed.

Peak torque is rated at 263 oz-in at 7.2V with a fast 0.10 sec/60-degree transit speed, giving strong holding power for direction changes under full 6S power. The servo operates on 6.0-7.2V DC, so it pairs directly with the adjustable high-voltage BEC output on modern ESCs.

The case is the industry-standard footprint at 1.58 in (40mm) long, 0.79 in (20mm) wide, and 1.55 in (39mm) tall, with the Spektrum 23-tooth output spline for broad servo horn compatibility.

ARRMA fitment includes the Kraton 6S BLX, Mojave 6S BLX, Typhon 6S BLX, Notorious 6S BLX, Fireteam 6S BLX, Felony 6S BLX, and Infraction V2 6S BLX. If a stripped or slow stock servo is holding your 6S truck back, this is the direct swap. The package includes one servo.
