Its compact dimensions make it perfect for weight-sensitive applications like RC aircraft, whilst the small footprint means it can fit into tight spaces in any RC build.
• Coreless Motor Design — The servo utilises a coreless motor, which provides smooth, efficient operation and reduces vibration compared to cored motor designs. This results in more precise control and a smoother feel during operation.
• Multi-Application Versatility — Primarily intended for air applications, this servo is also suitable for use in specialty RC cars, RC trucks, and RC boats, making it a genuinely versatile component that can be used across multiple hobby platforms.

Technical Performance

The SV1261MG represents exceptional engineering in a compact servo format. Operating at 7.4V, it produces 20kg (277oz-in) of torque whilst completing a 60-degree movement in just 0.095 seconds—a combination that places it firmly at the top tier of mini servo performance. At the standard 6.0V operating voltage, torque drops to 15kg (208oz-in) with a speed of 0.12 seconds per 60 degrees, still respectable performance but demonstrating the benefits of running this servo at its intended 7.4V HiPo specification. The servo features a precision coreless motor paired with a metal gear train and bearings that work together to deliver reliable, durable performance even under demanding conditions. The aluminium case provides both structural strength and superior heat management—critical considerations for extended operation sessions. Running current is specified at 180mA at 7.4V with no load, whilst stall current (under maximum load) reaches 4700mA, giving builders a clear picture of power requirements for battery planning. The servo operates across a wide temperature range from -10°C to 50°C (14°F to 122°F), making it suitable for use in varied UK climates. The 25-tooth spline output gears accept standard servo horns and control arms, whilst the 100-degree standard operating travel (adjustable to approximately 165 degrees with extended pulse width) accommodates most applications. With a refresh rate of 333Hz, the servo provides smooth, responsive control across all operating conditions.
