    Specifications of JR servo wire

    The majority of JR servo wire uses a common 3-pin connector and shares the same control signals, making RC servos mostly interchangeable.

    The fact that there are many color codes in use and that the wiring color code isn't always constant is one issue that may be perplexing. The good news is that although the colors may change, the pins are often in the same sequence.


    Specifications of JR servo wire:



    The color of the servo wire is black, red, and white. Power, ground, and signal are the three wires that servo motors have. Usually red, the power cable has to be attached to the Arduino board's 5V pin. A ground pin present on the Arduino board should be linked to the ground wire, which is commonly black or brown. With the aid of the third wire, known as the signal wire, the servo wires respond to the signals.



    The weight of the aircraft is a typical issue that affects flying performance, and the electrical components employed in the aircraft might have an impact on this weight. The extensions are one of these elements. The length and thickness of the wire have a significant impact on the weight of the wire. American Wire Gauge is a measurement that is often used to indicate wire thickness (AWG). In this gauge measurement, a higher number indicates thinner wire while a lower number indicates thicker wire.


    High-quality wire:

    JR servos have high-quality wires. They have a male connector on one side and a female connector on the other, making it possible to connect it to the steering engine and receiving set.


    How to safely connect the JR connector to the servo?


    Some of the servos may occasionally fail to connect to a JR extension because its male end is square around the edges, unlike the male ends of the Jr. and Futaba extensions, which are smoothened around the edges. Therefore, to connect the servo you must slightly polish the top edges of a JR connection. They may be quickly attached after being sanded down.



    Most of the major manufacturers of analog servos started to work together about 1991 or shortly after. Because of this, you may use any of these servo brands with any type of receiver, but you must be careful while connecting them in terms of polarity. Some servo brands are excellent for specific use in a specific aircraft, and other businesses sell their servos with connectors from other manufacturers already fitted you should know about the application you want to perform.


    JR Servo wire and Futaba Servo wire comparison:


    Have you ever wondered how to pick the best servo extension for your model aircraft? Is the JR type superior to Futaba, and if so, what makes them different? These issues are all covered in this article, which will also assist you in choosing the appropriate servo extension for your aircraft. Let's first discuss the specifics that distinguish the JR-type connector from the Futaba-type connector.


    Color of wire:

    The wire colors in a JR type are brown, red, and yellow. This is the first obvious change. Red is positive, brown is negative, and yellow is the signal wire. In a Futaba Type, the colors are Black, Red, and White. Remembering that your signal wire is always the lightest color—yellow in Jr. and white in Futaba—and that the negative lead is always the darkest color can help you avoid polarity confusion. Additionally, twisted wire extensions and JR Extensions in black, red, and yellow are available.


    Polarity of wire:

    Although the connectors are slightly different, the servo and battery connections in Futaba and JR Radio servos all share the same polarity (+/-) and signal to wire. You should only be careful about the polarity of these servo wires. The direction of servos can’t be changed by just swapping “+” and “–“wires. If you do, either the servo or the receiver—or both—will burn out. By switching the wires that link directly to the servo motor within the servo casing as well as the tiny servo wiper that moves, you can reverse the typical direction of the servo if you're particularly proficient at soldering extremely small wires.

    Applications of JR servo wire:


    • These servo extensions are appropriate for remote-control cars, RC cars, plane and helicopter servo connections, as well as JR and Futaba servos. These jumper wires are used on typical 0.1" breakaway headers.


    • Items that are used every day make use of servo motors. Servos are used to withdraw and retract disc trays in home electronics devices like DVD and Blu-ray players.


    • Servo motors are also used in automobiles. Servo motors are used in contemporary automobiles to regulate speed. The computer in the automobile receives electrical impulses when the gas pedal is depressed. After processing the data, the computer instructs the servo connected to change the engine speed. Even commercial airplanes utilize servos to push and pull objects within the aircraft.


    • Additionally, they are utilized for novelty goods like remote-controlled, scale-sized toy automobiles, robots, and aircraft. Servos are particularly useful for positioning control surfaces on radio-controlled aircraft.


    • However, servos are often employed in industrial settings. Servos are used in several significant sectors, including robotics, pharmaceuticals, food services, and in-line manufacturing.


    • Additionally, servos are best suited for electrically powered machinery including elevators, rudders, walking robots, and gripper actuators.
