Precision Micro Servo Futaba S3157M for tight builds

The Futaba S3157M Digital Micro Servo is engineered for precise motion in compact RC projects. Its light weight and dependable response make it a solid option for model pilots and builders working with limited space.

Performance Overview

This micro servo balances quick travel with respectable torque for varied RC tasks. At 4.8V it achieves 0.1 sec per 60 degrees with 1.5 kg.cm torque, and at 6.0V it improves to 0.09 sec per 60 degrees with 1.7 kg.cm torque, supporting both nimble and slightly heavier control demands.

Installation and Size

Measuring 21.8 x 11 x 23.2mm and weighing 7.9g, the Futaba S3157M installs easily into slim fuselages and confined radio bays without sacrificing reliable movement.

Will the Futaba S3157M work for rudder control on small models?

Yes, it is suitable for lightweight rudder or elevator duties where compact size and accurate centering are important.

Is additional gearing required for higher loads?

For heavier control surfaces or high-load uses, consider a servo with higher torque or a mechanical advantage; the S3157M is best for light to moderate loads.

How do I check fit before final installation?

Measure the bay dimensions and verify horn and screw positions against the servo footprint to ensure clearance and correct horn orientation.
