Sanwa ERS-963 Compact High-Torque Servo  [SW-ERS-963]

Sanwa ERS-963 Compact Servo for Serious Driving

The Sanwa ERS-963 is a compact digital waterproof servo with brushless motor technology, engineered for repeatable steering control and solid torque in 1/10 scale models. Its tough construction supports reliable operation across a range of driving conditions.

Longer Life with Brushless Motor

Brushless mechanics reduce internal wear and boost efficiency, helping the ERS-963 maintain smooth actuation over time. Hobbyists will notice steadier centring and fewer service intervals compared with older servo designs.

Reliable Sealing and Protection

The sealed construction keeps moisture and debris out, so the servo stays dependable on damp race days or when tackling rough outdoor terrain. That reliability makes it a good match for mixed-weather running.

Speed, Torque and Fitment

Delivering 0.15sec per 60 degrees at 6.0V and 23.0 kg.cm of torque, the ERS-963 combines swift response with ample force. At 40.3mm x 20.2mm x 35.9mm and 62g, it fits neatly in the majority of 1/10 scale bays.

If you need a compact servo that balances responsiveness with durability, the Sanwa ERS-963 is a practical upgrade for many 1/10 scale projects.
