For giant scale and precision competition airplanes, JR’s DS8411 servos are the ultimate choice thanks to their high output torque and incredible accuracy and holding torque. To transfer all that available power to the servo arm, JR’s DS8411 features a composite metal gear train that includes a combination of hard anodized hardened steel and brass gears that are virtually unstrippable. This combination of metals gives a long, backlash-free gear life. In addition, ball bearing spacing on the output gear has been significantly widened, offering greater radial output play and further improving accuracy.
JR’s digital amplifier, developed in cooperation with the electronics giant Mitsubishi, features a high frequency 250Hz pulse rate (the number of times per second the amplifier sends power to the motor) versus the 50Hz pulse rate of conventional servos. This provides quicker response and gives up to 5 times greater holding power.
