This is the Hitec D845WP Waterproof Monster Torque Steel Gear Large Scale Servo. The steel D-845WP is part of the D-Series servo line. All Hitec D-Series servos have been designed Hitec's cutting edge, custom engineering. Combining industry leading high-resolution, state-of-the-art ultra-response technology with a 32-bit MCU and 12-bit ADC for unprecedented programmability and flexibility, these servos deliver significantly smoother movement.

The speedy, powerful line operates on a wide 4.8 ~ 8.4 voltage range, allowing use with any common battery chemistry without the need for adapters or regulators. Featuring a 15 tooth HD output spline with 3mm hex screw, each D-Series servo brings monster performance never known before in the market.

NOTE: Losi Desert Buggy XL applications will require shimming at the servo or the servo tray, to raise the servo high enough to clear the chassis.
