Technical Performance

The SC1268SG+ represents a significant engineering achievement in servo design, combining Savox's all-new motor and controller technology to deliver class-leading performance across every metric that matters to serious RC enthusiasts. At 7.4V operation, the servo produces 25kg of torque (347.2 ounces-inch), enough to handle heavy steering and throttle loads in competitive 1/8th scale nitro racing applications and large scale aircraft without hesitation or servo sag. The response speed of 0.11 seconds per 60 degrees at 7.4V is extremely rapid, ensuring your inputs are translated into immediate physical movement with minimal lag—critical for maintaining control precision during high-speed manoeuvres and split-second racing decisions.

The servo's construction prioritises durability and longevity under sustained operation. The unique steel gear set with dual ball bearings (2BB) is engineered to withstand shock loads and continuous operation that would damage plastic gear alternatives, whilst the 25-tooth output spline provides secure horn attachment and reliable power transmission. The servo operates across a wide temperature range from -10°C to 50°C, maintaining performance in cold winter conditions and hot summer racing environments. Its 333Hz refresh rate ensures smooth servo operation without visible stepping or jitter, whilst the 12-bit digital resolution delivers precision positioning that translates to smoother steering response and more predictable vehicle behaviour on the track.

The running current at 7.4V is 150mA under no-load conditions, whilst stall current reaches 3500mA when the servo is locked in position, making it compatible with quality RC battery systems rated for these current draws. The standard 25-tooth spline output horn is universally compatible with most RC vehicles, and the 200mm black lead wire is of adequate length for most applications whilst the colour and quality ensure professional appearance and durability. The servo's neutral position is locked at 1500 microseconds, with standard operating travel of 100 degrees (1000-2000 microseconds) and maximum travel capability of approximately 130 degrees (900-2100 microseconds), offering flexibility in setup and configuration to match different vehicle requirements.
