Elevate your RC setup with Hitec’s D645MW Digital Servo, a robust, high-torque solution built for demanding radio control applications. Whether you're piloting a high-performance aircraft, navigating tough terrain with an off-road truck, or upgrading your robotics project, the D645MW delivers exceptional precision and durability.
Featuring a powerful cored motor, heavy-duty metal gear train, and advanced digital circuitry, this servo provides smooth, responsive control with consistent torque. Its high-resolution performance is ideal for hobbyists and professionals alike seeking reliability and speed.
NOTE: The D645MW is the upgraded version of the HS-5645MG.
Key Features
- High Torque Output: With a torque rating of up to 168 oz-in @ 6.0V, the HS-5645MG delivers exceptional strength for steering, throttle, and control surface applications.
- Metal Gear Train: Built with 1 MP (Metal + Plastic) & 3 Metal Gears, it provides long-lasting performance and increased crash resistance over plastic gear counterparts.
- Cored Metal Brush Motor: Designed with Hitec’s cored motor, the D645MW provides dependable speed, torque, and long service life.
- Ball Bearing Support: Even during heavy-duty use, the dual ball bearings on the output shaft ensure smooth operation and reduced wear.
- Universal Fit: Its standard size and 25 tooth output spline makes it compatible with the most popular RC platforms.
- 32-Bit High-Resolution Processor: This resolution ensures smooth, ultra-precise motion and excellent holding power.
- Fully Programmable: Via the Hitec DPC-20 and/or HFP-30 digital servo programmers, the performance of the D645MW can be fined tuned for customized response curves, fail-safe settings, and more.
