JR XP3810 Radio System (JR XP8103)

3 Radios In 1

The JR XP8103 is really 3 radios in 1. With its extensive list of specific software features for airplane, helicopter, and gliders, it's a radio that can handle your entire fleet of models and any you may be thinking of adding to it. The XP8103 was also designed with the notion that modelers would rather spend more of their time flying instead of programming their radio. As a result the XP8103 is loaded with sophisticated features that not only enhance your flying experience but simplify it as well. These include:

  • JR's 3+1 Digital Trims: JR's 3+1 Digital Trim arrangement utilizes Advanced Digital Trims on the roll, pitch, and yaw channels and a mechanical trim lever on the throttle channel - the setup most preferred by modelers we spoke to.
  • Auto Trim Memory: Moving the digital trim switches automatically stores the new trim position in memory for that model. This allows switching between model set ups without having to reset trim position each time and prevents accidental displacement of trim position when the radio is off.
  • Adjustable Trim Steps: This allows servo adjustment of 1 to 10 steps per "click" of the digital trim switches for fine or coarse adjustments of the trim position.
  • Audible Trim Position Tones: Trim position and direction of movement is audibly indicated with "beeps" of varying frequency and tone whenever a digital trim switch is moved. This allows modelers to make in-flight trim adjustments without taking their eyes off the model.
  • Easy-to-Read LCD Screen: Multi-point programmable curves, dual rates, and exponential settings are all graphically displayed to help take the guess-work out of getting the perfect mix.
