The Futaba S3156 suits modelers who prioritise compactness and dependable operation in small electric aircraft or light RTF models.

It can be used on small aerobatic models, but confirm the torque fits your control surface size and consider faster servos for aggressive 3D routines.
It uses a standard Futaba-compatible servo connector. Ensure your receiver or extension leads match the connector orientation.
Avoid overloading the servo and keep linkages smooth. Periodic checks for binding and light gear inspection after heavy use help extend gear life.
