FAQ

Does the Futaba S-U300 support S.BUS2? Yes, Futaba officially specifies the S-U300 as an S.BUS2-capable digital servo and it also supports conventional PWM and S.BUS operation

What torque does the S-U300 produce? Futaba specifies 3.2kg-cm at 4.8V and 4.1kg-cm at 6.0V

What servo horn spline does the S-U300 use? The output spline is 6mm diameter with 25 teeth

Can the Futaba S-U300 run directly on 7.4V? No, Futaba specifies an operating voltage range of 4.8V to 6.0V for the S-U300

Important Notes

• Do not exceed the specified 6.0V maximum operating voltage
• Confirm servo dimensions spline type voltage and torque requirements before installation
• Use only S.BUS2-compatible equipment on an S.BUS2 connection where required by the radio system
