Notes

The discontinued Align DS520 is a high-speed digital 'mini' servo that is designed to provide lightning-fast response times for the most demanding of helicopter applications. Building on the solid foundation of the DS510, the DS520 is optimized for speed, making it the ultimate choice for the tail rotor control of 500-class helicopters. Its blistering transit time allows it to keep up with the rapid-fire commands of modern heading-hold gyros and flybarless systems, resulting in a locked-in, consistent tail that holds steadfast through even the most aggressive of 3D maneuvers. The DS520's coreless motor provides instantaneous acceleration and a crisp, precise feel, giving the pilot the confidence to push the limits of their machine.
The DS520's impressive speed also makes it a formidable cyclic servo for pilots who prioritize agility and responsiveness above all else. When used on the swashplate of a 500-class helicopter, the DS520 delivers a level of quickness and agility that can transform the handling of the machine, making it feel more responsive and alive in the air. The servo's aluminum mid-case and durable composite alloy gear train ensure that this high level of performance is delivered with reliability and consistency. For the pilot who is looking for the ultimate in speed and precision for their 500-class helicopter, the Align DS520 is the definitive choice.

Application(s): TREX 500

Comments: As above stated are not true statements. These were due to failure of incorrect mechanical setups. Align makes a really good servo for the money and many in the hobby use these servo's without failure unless due to a crash. I personally have had zero issues with them and yes when i crashed they do strip sometimes but the rebuild kits are pretty cheap. Strong and fast servo's and performance achieved at half the cost compared to higher end servo's with similar spec's.

Application(s): trex500

Comments: these servos work fine while operating. the only problem is that they posses quite some slop in the gear, which resulted in me having to adjust cyclic trim on a random basis. the trim seemed to be different from flight to flight...
besides that they work fine, are fast and strong.
