If you thought JR's release of the DS8411 Digital Ultra Torque Standard Servo was
a breakthrough in power, precision, and durability, you're absolutely right. In fact,
this revolutionary servo has become JR's biggest selling premium servo ever! JR is
now introducing the same benefits of the Standard Digital Servo to a full range of
smaller servos, offering serious RC modelers a host of unprecedented options.
JR's new smaller 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.
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 .
