The HS-425BB is the best standard servo under $13. We love this servo for robotic projects because it is easy to modify for wheeled applications and it comes with dual ball bearings so it operates extremely smooth. We offer the HS-425BB in several configurations, 90° stock rotation, 180° modified rotation, continuous rotation (potentiometer is left outside the servo case) and reverse rotation.

 

 57 oz-in.

 

 0.16 sec/60°

This servo can operate 180° when given a pulse signal ranging from 600usec to 2400usec. Since most R/C controllers cannot generate this wide of signal range, you will need to purchase our servo stretcher for 180° operation.
