S3305 Futaba Standard-Size High-Torque Servo for RC Cars and Boats  [S3305]

Overview and Features of the S3305

The Futaba S3305 is a standard form-factor servo built with metal gears and a 3-pole motor to provide dependable torque for steering and control in hobby cars and boats. It uses Futaba's standard J-style connector and is backed by a one-year warranty from the maker.

The maker advises NiCd battery packs for this model and warns that switching to NiMH or LiPo may increase current draw. If you intend to use other battery chemistries, ensure your battery, receiver, and BEC or power distribution can cope with the servo's peak current requirements to avoid voltage sag.

Dimensionally the S3305 fits most standard mounts. The unit incorporates two ball bearings to reduce play, metal gear train for improved load tolerance, and arrives with a selection of horns to suit common linkage arrangements. Mounting hardware is provided to simplify installation.

As a standard-size servo, the Futaba S3305 offers a rugged metal-gear option for steering or throttle use in model cars and boats; match the horn and mounting to your linkage geometry and confirm the power setup can meet the servo's peak demands.
