Hyperion ATLAS Digital Servos                                   

ATLAS Digital High-Voltage DH Servos run on 6.0V~7.4V input, and are ideal for direct input via LiFePO4 or Lipo 2S receiver packs.  Models which use 2S main packs of between 6.6 and 8.4V - such as many gliders and RC cars - can power the DH servos from the main power pack, saving the weight and hassle of Rx batteries or BEC units.  Standard Voltage "DS" Series ATLAS Servos run on 4.8 to 6.0V nominal input.

  Top competition glider makers are the harshest servo critics in the world, and the very best are insisting on Hyperion DS09 servos for their models.  AVIONIK took the top spots in recent Japan Open F5B competition using Hyperion ATLAS servos, for just one example...

Hyperion ATLAS Digital, Programmable Servos are among the finest servos in the world.  They are made strictly to Hyperion specifications at one of the foremost electronics companies in South Korea, from components made only in Japan and South Korea.  The gears - a key element in any quality servo - are made to exceedingly fine specifications.  The CarbonPoly type, using a mix of long-polymer plastics and carbon fiber, more than double the sheer strength and wear compared to normal plastic gears.  The metal gears used in ATLAS servos are extremely tough and - because they are produced with very tight specifications - are also quiet, smooth, low-lash, and long-wearing.

In terms of centering accuracy, consistency, and ability to deliver rated torque regardless of temperatures encountered, ATLAS servo testers worldwide have favorably compared the ATLAS to the finest offerings from top Japanese servo producers.

Of course, the Hyperion ATLAS have some rather large advantages compared to other Digital Servos on the market.  They are fully programmable for a wide variety of settings, using an inexpensive USB adapter cable. And - considering the huge investment in precision molds and highest quality components Hyperion has made - they are very attractively priced.  You may find cheaper Digital Servos, but you won't find a higher value...

A note on specifications:  R/C modelers often consider torque to be the single most important specification when buying a servo.  As a result, the general trend has been for manufacturers to advertise very high torque figures for their servos.  In many cases, manufacturers simply pluck these figures "from the air", rather than base the figures on test results.  In other cases, the servo may perform as advertised - at least while cold - but draw very high current while operating.  Such high currents can cause models to crash when BEC circuits are overloaded, or receiver packs depleted - and servo life will always be shortened.

Hyperion has a different philosophy.  We have designed servos that draw lower-than-average currents; increasing safety, consistency of performance, and reliability/longevity as motors are never overstressed.  By using quality motors and digital technology, we are able to obtain dynamic torque figures which are always much more than adequate for each model application.  And due to the digital controller, "holding" torque figures are typically DOUBLE the dynamic torque figure. In short, our servos have all the torque you will ever need, combined with speed and reliability over a wide voltage range...

Atlas Digital Servos are programmable for a wide variety of settings, via either a USB Adapter or by Emeter II.

Here are some of the accessory horns available for 12~20 series servos, pictured below. We expect to also have single-arm CNC Aluminum horns - as well as RDS Adapters - for DS09/DS11 and DS095 Wing servos for release in AUG/SEPT 2010.
