Performance Focused Savox SH-1290MG Overview

The Savox SH-1290MG High-Speed Metal Gear Digital Servo delivers repeatable performance for RC helicopter pilots who demand accuracy. Its coreless motor and aluminium housing promote quick response and better heat handling. Sealed with four silicone rings for water resistance, it supports consistent control in a variety of field conditions and fits 500, 600 and 700 class heli installations.

What Sets the SH-1290MG Apart

Featuring a 4096 super high resolution and a digital controller, the SH-1290MG produces fine position steps and stable centring. The coreless motor contributes to smoother output under changing loads. Savox also follows environmentally conscious production practices. At 6.0V the servo delivers 69.4 oz-in of torque with a speed of 0.05 sec/60 degrees, suitable for demanding heli maneuvers.

Can I use this servo in dusty flying sites?

Yes. The silicone seals and water-resistant case help keep dust and light debris out, but regular inspection and cleaning are recommended after dusty flights.

Does the SH-1290MG need special gearing or horns?

It uses a 25T horn spline, which matches standard helicopter servo horns. Choose a horn rated for the torque to avoid flex in aggressive setups.

What power source is recommended for safe performance?

Use a stable BEC or regulated 6.0V supply capable of handling short stall currents up to the specified 3.0 A to ensure consistent speed and torque under load.
