Sanwa ERS-963 High Torque Waterproof Brushless Servo  [SW-ERS-963]

Power and Reliability from Sanwa ERS-963

The Sanwa ERS-963 is a compact, high-performance digital waterproof servo aimed at experienced RC hobbyists. Built around brushless motor technology, it produces consistent torque and fine steering control for most 1/10 scale vehicles, while a rugged build helps it survive demanding driving conditions.

Brushless Drive Benefits

The brushless system in the Sanwa ERS-963 improves efficiency and reduces internal wear compared to brushed designs. That means smoother operation, less maintenance, and longer service life for competitive use or regular club runs.

Sealed Waterproof Construction

With a fully sealed housing, the ERS-963 resists water and grime to keep performance steady in wet or dusty environments. This makes it a practical choice for outdoor practice sessions and off-road outings.

Control, Speed and Fit

Rated at 0.15 seconds per 60 degrees at 6.0V and 23.0 kg.cm of torque, this servo balances quick response with strong output. Its 40.3mm x 20.2mm x 35.9mm footprint and 62g weight drop into most 1/10 scale installations without major adjustments.

The Sanwa ERS-963 is well suited to anyone upgrading steering or throttle on a 1/10 scale rig who wants a reliable, high-torque option that copes with real-world conditions.
