JR NX8931 Programmable WV XBus Servo


This servo replaces the NX8921

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.

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 gain, dead band and boost to suit your aircraft and desired response. This precise setup allows servo hunting to be eliminated and precise feel maintained.

Purpose of use: For Aerobatic Aeroplanes in competition and Giant scale aeroplanes use.

NX series servos can be programmed for up to 180 degrees of travel, and can therefore be used as proportional retract servos.
