Weight:600g.Product included: 550kg Servo*1, Accessories: big Bracket *2,small Bracket *2,cable*1 - You can use like normal Servo or motor, DIY an advanced robot, robotic arms, PTZ cameras, Remote control vehicle, and other mechanical projects. At Motor Mode, you can use like wheel-drive, or DC motor. It can perfectly compatible with for Futaba, for JR, for SANWA, for Hitec and other remote systems and Arduino PCB - Two modes: servo and motor drive, which is selected by a DIP switch. In servo mode the shaft move 0-360 degrees for 5 to 20 mSec pulse width. There are gain and offset potentiometers to calibrate the motion . There is also a reversing DIP switch to change the sense of the rotation. - NOTE! As this is a high-power servo, so a high-power power supply (16-24V, 25A) is required, We recommend using 20V battery. - The signal port will provide 5V/1A for the control device, such as remote control receiver,arduino PCB, and we can greatly simplify the power supply of the device. - could double-shaft positioning: one is the driving shaft, one is the assistant shaft. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #132,756 in Toys & Games ( See Top 100 in Toys & Games ) #180 in RC Servos | | Customer Reviews | 4.5 out of 5 stars 53 Reviews | ## Images ![550kg High Torque RC Servo, 2 in 1 Servo and Motor 16V~24V High Voltage Full Metal Gear Digital Servo - Image 1](https://m.media-amazon.com/images/I/71MNZHVlZ+L.jpg) ![550kg High Torque RC Servo, 2 in 1 Servo and Motor 16V~24V High Voltage Full Metal Gear Digital Servo - Image 2](https://m.media-amazon.com/images/I/71K2sCsbgUL.jpg) ![550kg High Torque RC Servo, 2 in 1 Servo and Motor 16V~24V High Voltage Full Metal Gear Digital Servo - Image 3](https://m.media-amazon.com/images/I/719Sotad3xL.jpg) ![550kg High Torque RC Servo, 2 in 1 Servo and Motor 16V~24V High Voltage Full Metal Gear Digital Servo - Image 4](https://m.media-amazon.com/images/I/81ZoOC7s5fL.jpg) ![550kg High Torque RC Servo, 2 in 1 Servo and Motor 16V~24V High Voltage Full Metal Gear Digital Servo - Image 5](https://m.media-amazon.com/images/I/61dxQeDmiJL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Please can I use arduino uno to program this motor and also it need driver or not?** A: You do not need a driver, all you need to do is provide 12-24 VDC. I have corresponded with the manufacturer and they recommend 18 VDC. I plan to use this at about 21.5 VDC (what a typical 24 VDC power supply can be turned down to), in which the manufacturer approved as an upper limit. To control the servo, you need to provide a PWM signal, which I think is available from an arduino. The PWM needs to be at 50-400 hz and have a pulse width from 500 usec to 2500 usec. Sorry for the remedial math here, but .5 to 2.5 milliseconds would be the correct pulse width to make this go from 0 to 360 degrees of rotation. I have tested this with inexpensive RC servo test devices and it definitely works. There is 5 VDC available for the signal input, so you could use an open collector output. If the arduino has a lower voltage, such as 3.33 VDC, I'm not sure if that would work, but the sales data on Amazon supports this. This servo is accurate and has a great deal of torque. With 21.5 VDC power applied I was able to get about 67 rpm out of it. I hope this helps! **Q: How many amps does the servo pull at full power and 18V?** A: no load is 0.34A/18v, max load is more then 20A/18v, very powerful **Q: Are servo arms available for this product?** A: No but there are some cool examples on how to use this for a quadrupole robot **Q: Can this motor be used to steer wheel to specific angel? In continues servo mode?** A: Yes. The servo has two modes: servo position and motor drive, which is selected by a DIP switch. In servo mode the shaft rotation can move 0-360 degrees for 0.5 to 2.5 uSec pulse width. There are gain and offset potentiometers to calibrate the motion over any standard servo range. There is also a reversing DIP switch to change the sense of the rotation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***G on October 18, 2023* ### ⭐⭐⭐⭐⭐ Review *by R***K on December 30, 2025* ### ⭐⭐⭐⭐⭐ Review *by B***Y on March 6, 2026* ## Frequently Bought Together - DOCYKE 550kg High Torque RC Servo, 2 in 1 Servo and Motor 16V~24V High Voltage Full Metal Gear Digital Servo - DOCYKE Servo Accessories - DOCYKE Servo Tester 0-360° RC Digital Servo Tester Servo Manual Controller for RC Car Airplane Robots Tester Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/560004172-550kg-high-torque-rc-servo-2-in-1-servo-motor](https://www.desertcart.us/products/560004172-550kg-high-torque-rc-servo-2-in-1-servo-motor) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-10*
