Futaba S3305 High-Torque Standard Servo with Metal Gears  [S3305]

Futaba S3305: Product Summary

The Futaba S3305 is a standard-size, high-torque RC servo fitted with metal gears and designed for steering or control tasks in hobby cars and boats that require a durable actuator. It uses a 3-pole motor and connects via the standard Futaba J-style connector, and the unit is covered by the manufacturer's one-year warranty.

The manufacturer recommends NiCd battery packs for this model and cautions that NiMH or LiPo systems can lead to higher current draw. If you plan to run the S3305 from NiMH or LiPo, make sure your battery, wiring, and receiver or BEC can supply the peak amps to prevent receiver brownouts.

Mechanically this servo follows a standard footprint and fits most common standard mounts. It is fitted with two ball bearings to reduce shaft play, metal gears for improved durability under load, and includes basic horn options to match typical linkage setups. The package supplies mounting hardware and horn choices suitable for steering or throttle tasks.

For standard-size RC cars and boats that need reliable steering or throttle control, the Futaba S3305 offers a metal-gear, high-torque option in a common footprint; select the supplied horn that provides the mechanical advantage you need and confirm your power system can meet peak current demands when tuning performance.
