S-U300 - FUTABA STD UNIVERSAL SERVO S.BUS .19SEC/4.1KG 36g

Reliable Standard Servo for Multiple Applications

The Futaba S-U300 is a dependable, standard-size servo designed to deliver smooth and accurate control for a wide range of RC models. Whether you're operating an RC car, plane, boat, or other compatible model, this servo offers consistent performance at an affordable price point. It combines ease of use with Futaba's trusted build quality, making it an excellent choice for hobbyists of all levels.

Balanced Speed and Torque Performance

With a rotation speed of 0.23 sec/60° at 4.8V and 0.19 sec/60° at 6.0V, the S-U300 offers responsive movement suitable for steering, throttle control, or auxiliary functions. Its torque ratings of 44.4 oz/in (3.2 kg-cm) at 4.8V and 56.9 oz/in (4.1 kg-cm) at 6.0V provide sufficient force for standard RC applications without excessive weight or power draw.

Durable, Lightweight Construction

Weighing only 1.26 oz (36 g), this servo is light enough for models where every gram matters. The plastic gear train keeps weight and cost low while still providing reliable durability for general RC use. The 3-pole cored motor delivers smooth motion, and the internal 6 mm / 25T spline output ensures compatibility with standard servo horns and linkages.

Compact Standard Dimensions

Measuring 1.6 in x 0.8 in x 1.4 in, the S-U300 fits the universal standard size for RC servos, allowing easy installation in most model setups without modification. Its compact form factor makes it ideal for smaller spaces while still delivering enough performance for steering systems or other control mechanisms in a wide variety of models.

S.BUS Compatibility for Enhanced Control

This servo is fully compatible with Futaba's S.BUS system, enabling simplified wiring and more advanced programming options when used with S.BUS-enabled receivers. This allows hobbyists to customize parameters such as travel, speed, and center points, giving more flexibility and precision compared to standard PWM-only servos.
