Futaba S3003 Product Summary

The Futaba S3003 is a straightforward standard servo that hobbyists rely on for routine steering and control tasks. It serves as a modern substitute for older Futaba parts like S138, S148, S22, S38, and S12, providing predictable performance in everyday models.

What to Expect from the Futaba S3003

Built with nylon gearing to reduce noise and wear, the S3003 moves at 0.23 sec/60 degrees when fed 4.8V and 0.19 sec/60 degrees at 6V. It delivers 44 oz-in (3.2 kg-cm) torque at 4.8V and 57 oz-in (4.1 kg-cm) at 6V, while its 40 x 20 x 36mm dimensions keep it compact for tight servo bays.
