Futaba S-U300 Overview and Fit

The Futaba S-U300 Standard Servo is a flexible replacement for the common S3003 unit. Built for everyday hobby use and club racing, this servo delivers a steady mix of speed and torque while using plastic gears for dependable, consistent operation.

Performance Figures for Tight Control

Measured at 0.23 seconds per 60 deg at 4.8V and 0.19 seconds per 60 deg at 6.0V, the S-U300 responds quickly to steering and throttle inputs. Torque measures 3.5 kgf.cm at 4.8V and 4.5 kgf.cm at 6.0V, giving enough grunt for many standard RC roles.

Compact Dimensions and Power Range

The S-U300 has compact dimensions of 40.4 x 19.8 x 36.0 mm and a weight of 36 grams, making it easy to fit into tight servo bays. It accepts 4.8V to 6.0V power supplies so it works with common receiver battery setups.

Will the S-U300 plug into my standard receiver?

Yes. The S-U300 uses the standard servo connector and is compatible with most receivers that accept standard servo plugs, especially where S3003 style servos were used.

How durable are the plastic gears?

Plastic gears on the S-U300 provide a good balance of light weight and durability for general use. They perform well for everyday driving and club racing but check for wear if you run hard or crash often.

Which voltage gives the best feel?

Running at 6.0V improves both speed and torque, yielding crisper response. If your system limits you to 4.8V, the servo still offers reliable performance for typical setups.
