JR DS3421 Digital Mini Metal Gear Servo

[JRPSDS3421]
JR's new smaller sized Digital Ultra Torque DS3421 Mini Metal Gear servo offers outstanding holding torque and quicker response. This is achieved by using a high-frequency digital amplifier with a pulse rate of 300Hz (the number of time the amplifier pulses the motor per second) versus the 50Hz found on a conventional servo. The extreme accuracy of digital precision gives a resolution of 5900 steps per 120 of travel and less than .001ms of dead-band. A durable composite-metal geartrain composed of hard-anodized aluminum and hardened steel and brass gears provides backlash- free operation.

Imagine locating servos where no servo has gone before. Due to their compact size, these small digital ultra-torque servos are perfect in applications that require servos driven by space restrictions, such as those found in a jet, sailplane, pylon racers, or a complex scale model. Eliminate long accuracy robbing link-ages by locating servos closer to the point of operation.

If you need to trim weight, you can lighten a model by choosing a smaller digital ultra-torque servo without the worry of losing torque normally associated with a larger standard servo. In fact, the Ultra-Torque Mid, Mini, and Micro servos all have more torque than most conventional standard servos and weigh considerably less. These servos are truly in a class of their own.
