  • 【Excellent Quality Workmanship】:The 21G Micro Digital Servo made with excellent Plastic Shell material (lightweight and fast heat dissipation) and high-precision Full Metal Gear (more durable and prevent tooth sweeping) with Hard Anodizing, combined with Dual Ball Bearings, has a longer service life.
  • 【High Performance Digital Standard】:The 21G Mini Digital Servo with Extra Large Torque can achieve Low Noise, Good Stability, Small Vibration, Smooth Operation, Excellent Linearity, Precision Control, Fast Response.
  • 【Electronic Protection】:The DS-S007M 21G Servo will undergo current reduction and power outage treatment when the locked rotor time and current exceed the preset values, preventing blockage and burning. A solid hardware foundation combined with more advanced software allows the servo to provide high torque output while significantly reducing the probability of damage to the servo under high loads.
  • 【Widely Use 】:The Mini Digital Servo is suitable for remote control vehicles such as Crawlers, Buggy, RC Car, Boat,RC Aircraft,RC Helicopters, On-Road,Off-Road,RC Drones,Toys,etc.Especially this servo is most suitable for micro control fields such as aircraft models, drones, toys, intelligent switches, etc.
  • 【Note】:In the frequency range of 500~2500us, the maximum controllable angle of the servo can be accurately achieved at 180 degrees, and the servo can achieve a control angle of 90 degrees under the control of a transmitter.


Product Description

Case Presentation-21G Micro Servo

High Quality 21G Digital Servo Suitable for Various Scenarios

DSPOWER high quality 21G Plastic Mini Digital Servo. One of the standout features of this servo is its impressive high torque and fast response in a lightweight condition, this means that it can handle heavy loads and provide a lot of force for RC Airplane or Robot. In addition to its strength, all metal gear can bring better collision resistance to the servo, making it more durable. At the same time, it also has excellent performance such as high control precision, good linearity and fast response speed.

DSPOWER high quality Digital Standard Servo can be widely used in 1:8, 1:10, 1:12 RC Car, Crawlers, Buggy Off-Road, Boat, Aircraft, Helicopters, On-road, ,Robot and other vehicles requiring high torque and waterproof. Whether it is hot rock, Gobi, beach, or wet rainy environment, it can still play superior performance.

It's a good choice for people who are interested in RC Model!

High Torque

Through our professional tests, the data of the 21G RC servo's Stall Torque (static) under the torque pound test is greater than or equal to 4.2Kgf.cm(6.0V), and the data of the Weighting Torque (dynamic) under the lifting test is greater than or equal to 1.5Kgf.cm(6.0V).

This Micro servo with strong torque can provide greater output force for your RC model.

High Torque-21G Servo
Waterproof-21G RC Servo

Waterproof Design

Excellent waterproof performance, the digital servo can easily handle complex road surfaces containing sediment, ice, snow, and water under various climatic conditions.

Full Metal Gear/Plastic ABS Shell

The error of precision machining metal gears is very small, which can prevent tooth sweeping, making your digital servo more durable.

The plastic shell has good heat dissipation effect, which is very light and durable, making it very suitable for RC drift cars and RC aircraft, robot, etc.

Full Metal Gear-21G RC Servo
Rotation Degree-180° 21G RC Servo

Rotation Degree：180°

When the pulse range of the input signal is between 0-2500 uSec, the control angle of the servo is 180 degrees.

No Load Speed:

  • 4.8V--≤0.10Sec/60°
  • 6.0V--≤0.12Sec/60°
Triple protection function-2KG RC Low Profile Servo

Triple protection function

The Triple protection function avoids burnout caused by excessive use or other environmental factors, effectively protecting the rc steering servo and extending its service life.

Bought these on chance. I am not disapointed yet. They are strong, but noisy. Seem to have decent control with a servo testor.

They are a bit noisy, but have not had any issues with them so far. Used them for steering in a hobby-swap RC project and they fit and work great.

I'm using this in a fighting robot and running them at 11.1 volts. They are frequently stalled. No failures. Very reliable.

These do not fit the TRX4M and I have 2 of them so I can use them in one of my 1/10th scale cars

I bought these to put in a plane that had plastic geared servos. They have lots of torque but they are so slow. You can count one one thousand going from full stop to full stop. Not great when flying aerobatics or hovering.
