The DSP60J is a digital servo housed in an attractive transparent grey case and features programmability with Spektrum's Digital Servo Programmer (SPMDSP). It also has JST connectors that are compatible with Spektrum AR6300 Nanolite receiver (SPMAR6300). The DSP60J offers superior speed, torque, and precision for its class, and includes complete mounting hardware and an assortment of servo arms.

The DS821 is Spektrum standard digital servo design. The servo is the equivalent to the JR DS589 from which it’s based. The servo accepts standard JR output horns and features a new longer-lasting gear train. The servo is a perfect upgrade for sports pilots in small/medium size applications. Not recommended for helicopter use or installations subject to high vibration levels. Key Features: New, longer-lasting plastic gear material Same size as standard servo Ball bearing-supported output shaft JR servo lead and plug.

The DSP75 offers superior speed, torque and precision for the class, and includes complete mounting hardware and an assortment of servo arms. You can optimize its performance for specific applications like airplanes, helicopters and tail rotors, by adjusting the end points, gain and even direction using the Digital Servo Programmer (SPMDSP- sold separately) The DSP75 is a great choice for parkflyers as well as mini- and micro-helis.

Spektrum's Digital Servo Programmer offers the ultimate combination of precision and customization for digital micro servo users. Features like 3-point programming, high-speed input and three servo modes make the Digital Servo Programmer perfect for park flyers, micro heli pilots and indoor foamie pilots. The DSP allows users to program their servos for optimum operation in whatever function they need, and the customization potential offered by the Digital Servo Programmer lets micro servo users experience the precision and smooth response offered by larger servos and aircraft without sacrificing performance.

Spektrum’s optional Flight Log is a unique tool that allows you to view the performance of your radio system like never before. With the revolutionary Flight Log, you can now quickly and easily view the real-time voltage supplied to your receiver, how many fades each internal receiver and remote receiver gets each flight, and see if the system received any frame losses or failsafes (holds). The Flight Log is an optional component that was originally designed for testing, but now it is offered as a handy device that gives you a clear digital read-out of your radio performance. The flight log is not required, but for complex aircraft, it provides an intuitive analysis of the overall performance of the radio installation. Some of today’s models can be very demanding. The Flight Log ensures confidence that your system is working properly and you have optimized the radio installation. The Flight Log provides the following information: System voltage - receiver pack voltage Antenna fades – represent the loss of a bit of information on that specific antenna. Typically it’s normal to have as many as 50 – 100 antenna fades on any one of the antennas during a flight. If any single antenna experiences over 500 fades in a single flight, the antenna should be repositioned in the aircraft to optimize the RF link. Frame Loss – represents simultaneous antenna fades on all attached receivers. If the RF link is performing optimally, frame losses per flight should be less than 20. Hold – a hold occurs when 45 contiguous (one right after the other) frame losses occur. This takes about one second. If a hold occurs during flight, it’s important to re-evaluate the system, moving the antennas to different locations and/or checking to be sure the transmitter and receivers are working correctly.
