Savox SH-1290MG: Compact High-Resolution Servo

The Savox SH-1290MG High-Speed Metal Gear Digital Servo combines a coreless motor with a robust aluminium case to deliver steady, repeatable control. Its sealed design with four silicone seals helps keep moisture and grit out, while the construction supports reliable operation in 500, 600 and 700 class helicopters that need fast, accurate actuation.

Technical Strengths of the SH-1290MG

Boasting 4096 super high resolution and a digital controller, the SH-1290MG gives refined positional control and consistent centring. The coreless motor improves dynamic response and smooth torque delivery. Savox follows eco-aware production methods. At 6.0V it provides 69.4 oz-in of torque and a speed of 0.05 sec/60 degrees, suitable for precise heli control demands.

For pilots wanting refined control and a sealed, durable package, the Savox SH-1290MG is a compact servo that supports demanding helicopter flight profiles.

How should I maintain the seals after flying in wet conditions?

After wet flights, wipe the case and check the silicone seals for debris. Avoid immersing the servo, and inspect linkages to keep water from working into bearings over time.

Will the SH-1290MG work with standard helicopter receivers?

Yes. The servo uses standard PWM control via pulse width modification and the 25T horn spline suits commonly available helicopter servo horns.

Is additional cooling ever required for long flights?

The aluminium case helps dissipate heat, but if you run prolonged high-load sessions consider airflow around the servo bay and avoid packing components tightly against the case.
