JR DS3717HV High-Voltage High-Speed Mini Servo MG


JR - JRPS3717HV - DS3717HV High-Voltage High-Speed Mini Servo MG

The JR 3717HV servo is the latest update to the JR mini servo lineup. Based on the original and successful DS3517MG servo, it has a new JR high-voltage motor, allowing it to be used unregulated when using 2-cell Li-Po power. With the added performance generated by the new HV motor, this servo packs quite a punch. It has many options for use, including 500-size helis and many sailplane configurations, and is suitable for the many new jet offerings now available to the market, especially the new and exciting EDF’s.

Battery chemistries such as Li-Po, Li-Ion and Li-Fe have become very popular within the RC community. They are the standard for powering electric motors and have also gained popularity as receiver battery packs. The issue is the output voltage of these batteries is higher then the previous standard 4- and 5-cell Ni-Cd and Ni-MH packs, 4.8V and 6V respectively. The higher voltage is not an issue with the receivers but can be for the servos. Many servos will not operate at these higher voltages for very long before burning out the motors or electronics.

To get around this issue modelers have had to use a regulator to drop the voltage to an acceptable operating range for their servos, usually around 5–6 volts. The addition of a regulator adds a component that, should it fail, can cause the loss of a model.

JR HV servos are designed with motors and electronics that operate off the direct voltage of a 2-cell Li-Po, Li-Ion or Li-Fe receiver battery pack (6.6-7.4V nominal voltage). This eliminates the need for a regulator and lowers the chance for a power failure that can cause a catastrophic failure of your model. Also note that the HV servo specs are shown at the higher voltage (7.4V 2S Li-Po) but will still operate on a standard 5-cell 6V Ni-Cd or Ni-MH battery with a reduction in performance of approximately 10% in speed and torque.
