High-Speed Helicopter Servo Savox SH-1290MG

The Savox SH-1290MG High-Speed Metal Gear Digital Servo is engineered to deliver quick, precise control for helicopter builds. Its coreless motor and aluminium chassis reduce thermal build-up while maintaining consistent output. The sealed design with silicone gaskets provides water resistance for varied flying conditions, making it a solid upgrade option for 500, 600 and 700 class helis.

Performance Highlights for SH-1290MG

Equipped with 4096 super high resolution and a digital controller, the SH-1290MG delivers fine positional accuracy and stable centring. The coreless motor improves smoothness and response. Savox follows greener manufacturing practices as well. Performance figures include 69.4 oz-in torque at 6.0V and a speed of 0.05 sec/60 degrees, suitable for responsive cyclic and tail work.

How durable is the aluminium case under heavy use?

The aluminium case improves heat transfer and mechanical protection compared with plastic shells, helping the servo cope with prolonged runs and higher ambient temperatures.

Is the resolution suitable for precise tail control?

Yes. The 4096 super high resolution combined with a digital controller gives very small positional steps, useful for tight tail tracking and smooth cyclic inputs.

Does the connector length suit tight frames?

The wire comes at 300±5 mm length and 22 AWG gauge, which fits most standard frames; trim or secure the cable as needed to prevent snagging.
