Futaba S3115 Micro High Torque Flight Servo  [S3115]

Precision Micro Servo: Futaba S3115

The Futaba S3115 Micro High Torque Servo provides accurate control for electric planes and small helicopters where space and weight are limited. Its compact profile and nylon gear train make it a solid choice for model flyers seeking consistent input to control surfaces.

Suited to Electric Flight Models

Optimised for electric applications, the S3115 produces 39 oz-in (2.8 kg/cm) of torque at 4.8V with a speed of 0.15 sec/60 degrees. Measuring 28 x 13 x 30mm and weighing 17g, it slips into narrow servo bays on scale and sport models.

Nylon Gear Advantages

The servo employs nylon gears for quiet, smooth movement and reasonable durability under normal RC use. Those planning to fit the unit on gas or very high power models should consider metal-geared alternatives for heavy duty service.

The Futaba S3115 is a reliable micro servo option for model builders working on electric aircraft who need compact, accurate control.
