Overview

Spektrum™ high-voltage, brushless servos deliver dependable power and digital precision with amazing efficiency. Finely tuned electronics and software integrate with powerful brushless motor technology to offer ultra-powerful/ultra-fast heli performance more efficiently than servos with conventional motors. Heavy-duty servo lead-wire includes the convenience of a quick-release cable connection. The all-aluminum case provides the ultimate solution in durability and heat dissipation. Precision metal gears satisfy even the most critical racer who wants hassle-free control.

The Spektrum S6340BL uses this solid foundation to achieve its wicked-quick .07 second transit time and incredibly strong 241 oz-in torque rating, plus the peace-of-mind over-current and over-temperature protection offers. It’s a brilliant feature combination that, along with its low-profile size, makes it an outstanding servo choice for any driver who wants precision control in a 1/10-scale sport or racing vehicle.

FAQs

What's the difference between digital and analog servos?

Digital and analog servos have very similar construction and components. They both use the same type of motors, gears, cases, and have a potentiometer. A digital servo is different in the way it processes the incoming signal and converts that signal into servo movement. 

An analog servo when it receives a command to move, takes that signal and sends pulses to the servo motor at about 50 cycles per second, which in turn moves the motor to its required position determined by the potentiometer.

A digital servo has a micro-processor that receives the signal and then adjusts the pulse length and amount of power to the servo motor to achieve optimum servo performance and precision. A digital servo sends these pulses to the motor at a much higher frequency which is around 300 cycles per second. This helps eliminate deadband, provides a faster response to the servo motor, smoother motor movement, and has higher resolution and holding power than an analog servo.

There are some disadvantages to digital servos, but the disadvantages are not in any way close to out weighing the advantages. A digital servo will have a higher power consumption (Around 10 to 15 mAh per servo at idle) than an analog servo due to its higher pulse frequency, so larger capacity battery packs are recommended. Digital servos also are more expensive than analog servos which can get very costly in applications that require many servos.

What grease should I use on my servo gear train?

For JR servos we recommend Tamiya ceramic grease (TAM87025).

Why doesn't my servo center properly?

There are several scenarios which may attribute to this problem.

1. The servo arm fit on the output spline may be loose.

2. There may be slop or wear in the gear train.

3. There may be slop or binding in the linkages.

4. You may have a faulty servo saver.

5 The push rods may be too flexible.

6. Improperly mounted servo (screws too tight, mounting rail too tight against the servo)

7.Faulty extention, damaged lead or dirty connector.

8. Worn or dirty pot.
