JR's small-sized Digital
Ultra Torque DS3421 Mini, 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.
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
Need to trim weight?
Lighten your model by choosing a smaller digital
ultra-torque servo without losing the torque of a larger
standard servo. JR's
Ultra-Torque Mid, Mini, and Micro servos all have more
torque than most conventional standard servos and weigh
These servos are truly in a class of their own .
