DFA is pleased to announce the release of our new XBus programmable servos, allowing not only serial servo connection, but also individual servo programming with servo adjustments to suit every application. 

Highlights : 
This servos automatically detect the type of output they are plugged into - conventional receiver PWM outputs, or XBus. This means Programmble servos are XBus compatible, and also compatible with PWM receiver signals without any converter, allowing modelers to use conventional receiver systems. 
* Compatible receiver systems : DMSS · DSMJ · 72MHz · 40MHz 
 
*Wide Voltage
* Double ball bearings
* Slow start function
*Compatible with any radio using PWM control
*XBus compatible allowing *120 to 180 deg travel
* featureYou can adjust Dumping,Hold,Deadband...etc
* Do not use this servo under the different voltage other than specified
* If used on a large and Heavy control surface
*Try to adjust Dumping.Hold .Dead band.Boost etc... You will set it up perfect condition.(use RX Xbus port    and Xbus TX)
