9 best mini servos for rc models

Mini servos are small, lightweight devices used in the field of remote control (RC) modeling and hobbyist applications.They play a crucial role in controlling the movement of various components in RC models, such as airplanes, cars, boats, and drones. Here is what you need to know about mini servos:

  1. Function: Mini servos are essentially small motors that can rotate a shaft to a specific position. They are used to control the movement of control surfaces, such as ailerons, rudders, elevators, and flaps in RC aircraft, or the steering and throttle in RC cars.

  2. Size and Weight: As the name suggests, mini servos are compact and lightweight. Their small size allows them to fit into tight spaces within the RC model without adding excessive weight, which is crucial for maintaining balance and performance.

  3. Types of Mini Servos: There are various types of mini servos designed for specific applications. These include standard servos (for general-purpose control), digital servos (for precise and fast movement), and analog servos (for basic applications). The choice depends on the specific needs of the RC model.

  4. Torque and Speed: Mini servos come in different torque and speed ratings. Torque determines the servo's ability to exert force, while speed dictates how quickly it can move. The choice of servo should align with the requirements of the RC model and the control surface it operates.

  5. Compatibility: Mini servos are compatible with a wide range of RC receivers and transmitters, making them versatile components in the world of RC modeling.

  6. Power Source: Mini servos typically operate on a low voltage (around 4.8V to 6V) and can be powered by the RC model's battery pack or a separate power source. It's essential to provide the correct voltage to prevent damage to the servo.

  7. Construction: Servos consist of a motor, gears, a control circuit, and a potentiometer. The motor drives the movement, while the gears ensure precision. The control circuit interprets signals from the RC receiver and adjusts the servo's position accordingly, with the potentiometer providing feedback on the servo's current position.

  8. Installation: Installing a mini servo in an RC model typically involves securing it in place using mounting brackets and linkages to connect it to the control surface.

  9. Remote Control: Mini servos are controlled remotely by signals sent from an RC transmitter. The transmitter allows the operator to make precise adjustments to the control surfaces, enabling the RC model to perform various maneuvers.

  10. Hobby and Enthusiast Use: Mini servos are popular among hobbyists and enthusiasts who enjoy building and customizing RC models. They are essential components in the world of remote-controlled vehicles and aircraft.

Mini servos are vital for achieving precise control and maneuverability in RC models, making them indispensable for hobbyists and enthusiasts who enjoy remote-controlled vehicles and aircraft. The choice of mini servo depends on the specific needs and performance requirements of the RC model in question.

KOOKYE 2PCS Mini Servo Motor 360 Degree Continuous Rotation w/Servo Horn Set (Arm, X, Wheel, Star) for RC Car Robot Helicopter Airplane Model

Based on 53 reviews Check latest price

Product description

The signal terminal needs to be input with one 50 HZ square wave, then the duration of high level pulse, which is used to control signal cycle, can control speed and forward/backward rotation as well as stalling. The duration of high level corresponds to a speed. When high level is 1ms~1.5ms, servo rotates forward(the rotate speed is the fastest when it is 1ms, the higher the lower, servo will stop rotating when reaching 1.5ms). When high level is 1.5 ~2ms, the servo rotates backward(The servo stops rotating when reaching 1.5ms, when the duration is closer to 2ms, the closer, the faster. The backward rotation speed, the fastest when reaching 2ms)



This servo carries meso-position adjustment potentiometer(it can only be seen by peeling off the outer cover and circuit board). We can set high level pulse at 1.5ms to observe that whether servo stops rotating. If it doesn't stop rotating, we keep adjusting the potentiometer until it does.

User questions & answers

Question: On the ds-04 360 degree motor, how can i stop it from suddenly moving/jumping when i attach power for first time
Answer: Let us be clear about this up front, the 360 degree RC (Continuous Rotation) servo can never stopping at a given location like the 180 degree or 90 degree servo. The 360 degree RC servo just spin around in one direction or another, varying speed. For 360 degree RC servo,If using arduino. write 90 for stop moving. You could write 0 for full speed in one direction and 180 for full speed in another to control the servo speed. For 180 degree and 90 servo, you could control it at a given location.
Question: How many teeth are on the spline? (Generally 24 or
Answer: there 25 teeth, that is if I didn’t double count a tooth. The outside diameter is 6.8mm
Question: What size coupler would fit on the DS04 servo
Answer: The coupler diameter of DS04 servo is 5 mm.
Question: is there any simple tutorial / or code example that works with arduino
Answer: Hi ,there are lots of tutorials about servo motor on our kookye website(www.kookye.com). You could visit the following links for your reference:http://kookye.com/2017/01/06/use-raspberry-pi-to-driver-servo-motor/http://kookye.com/2016/10/30/using-arduinorfidlcdservo-to-make-sample-security-project/http://kookye.com/2016/12/13/use-nodemcu-to-control-servo-motor-through-mqtt-iot-protocol/http://kookye.com/2016/04/19/drive-servo-motor-with-raspberry-pi/You could click the tutorial and search servo motor, and there are some simple tutorials and code examle.
Question: Has anyone tried running these at higher than 4.8 volts? I want to know if I can get away with running them at 5.5v
Answer: Yes,Working voltage of this servo is 4.8-6.0V ,but is do not exceed 6v, otherwise it will be burned.

Question: Will this servo fit a traxxas rustler
Answer: Yes,this rc servo can fit traxxas rustler
Question: Does the pulse width need to vary beyond the range produced by a typical hobby receiver to get the full 270 degree rotation
Answer: Yes,you're right! Generally speaking, the output pulse width of the remote control is in the range of 1000-2000,so the displayed angle is 135 degrees;To get the full 270 degrees rotation, the output pulse width should be 500-2500. :)
