This is the Spektrum AR400 4-Channel DSMX Aircraft Receiver. The Spektrum full-range AR400 receiver is easily one of the best receiver values on the RC market.


  • 2048 resolution
  • Antenna is amplified for greater signal clarity
  • Flight log and telemetry compatible
  • Full-range DSMX receiver
  • 4-channel - throttle, elevator, aileron and rudder channels for park flyers, trainers and most sport planes

The Spektrum AR400 combines the signal security of an active amplified antenna with the speed and precision of DSMX control. This antenna enables the AR400 receiver to "see around" reflective materials on a model and avoid antenna polarization blind spots. It also allows the Spektrum AR400 receiver to pick out its transmitter's signal with remarkable clarity in the noisiest 2.4GHz environments.

All of this is complemented by the security of Spektrum QuickConnect technology and SmartSafe failsafe protection, providing lightning-fast reconnection in the event of a low-voltage brownout.

The Spektrum AR400 receiver is not compatible with the DX6 park flyer radio system.
