We are pleased to be stocking JR Propo's XBus NX series servos, allowing not only serial servo connection, but also individual servo programming with servo adjustments to suit every application

The NX range of servos automatically detect the type of output they are plugged into, conventional receiver PWM outputs, or XBus. This means NX series 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/DSM2/35MHz/40MHz

When used on a JR XBus system, the NX series servos can be programmed in ways not previously possible. No additional programming device is necessary these servos can be setup using a JR XG series transmitter.

Changes made to servo programming are immediately apparent. Not only can servo direction and travel be adjusted, but it is now possible to fine tune servo holding power, stopping speed, deadband, starting power, total servo travel and slow start to suit your aircraft and desired response, you can even set an alarm if the servo exceeds the user set limits. This precise setup allows servo hunting to be eliminated and precise feel maintained.

This servo features an upgraded heatsink center case to improve cooling. If you are looking to take the performance of your model to unprecedented levels then the JR NX smart servos must be your first choice.

These servos are perfect for serious IMAC competition aircraft as well as giant scale aircraft, or anywhere where you require one of the best servos on the market.

* Do not use this servo with any other voltages other than those specified.

** If used on a large control surface - typically aileron, rudder, elevator or flaps on an airplane, digital servos may move slightly around center while on the ground. This is an expected phenomenon, and will not occur in the air.

  • Servo Torque(kg)(min. 0.01kg) 36.50
  • Servo Speed (Sec/60deg) 0.13
  • Servo A(mm) 46.00
  • Servo B(mm) 40.00
  • Servo C(mm) 40.00
  • Servo D(mm) 21.00

sehr gutes Servo aber leider noch zu teuer! Bin aber im ganzen begeistert von der Idee von Hobbyking. Gute Sache hier, bestelle immer wieder mal was und das in einer Woche alles bei mir in der Schweiz ist, ist Super.

Danke Hobbyking TEAM!
