The S3411 is the king of precision. Don't take our word for it though, listen to former NASA engineer Jerry Budd talk about the results of his independent servo centering tests in the July '22 K Factor

"...the JR 9411 and 3421 being clearly the best at centering, albeit much slower... I recently tested the new JR 3411 Comp 2K servo and it approaches the JR 3421 in terms of centering, but at a much higher speed and slightly greater torque output."   -Jerry Budd, Former NASA Engineer and Pattern Masters 2nd Place NATS Finisher

The JR PROPO S3411 “Competition" Servo adds a CNC upper metal case, increasing rigidity where it counts the most, at the top of the servo. Expect reduced stress and overall longer life span of the gear train.

This servo has a metal B (second) gear
