This is the Sanwa ERB-871 Low Profile Brushless Competition Servo, with detachable wires. Tough, fast and strong - this brushless servo has all the characteristics a demanding racer needs. An aluminum center case and lower plate provide improved cooling and stiffness while metal gears provide long life and durability under race conditions. The addition of a detachable lead allows you to tailor the servo to a variety of applications, and replace the wire easily if it gets damaged. Plus, the servo features waterproof circuitry for added peace of mind.

The Sanwa ERB-871 allows you to take full advantage of your ultra-fast response M12 or MT4S Sanwa Radio system (the two fastest radios in the world). This narrow-pulse-width servo uses Sanwa's unique SSR technology for unbelievable response time. You'll feel more connected and in command than ever.
