The full-range Spektrum™ AR400 receiver is easily one of the best receiver values in RC. It combines the speed and precision of DSMX® control with the signal security of an active amplified antenna. This antenna enables the AR400 receiver to "see around" reflective materials on a model and avoid antenna polarization blind spots. It also allows the AR400 receiver to pick out its transmitter's signal with remarkable clarity in the noisiest 2.4GHz environments. All of this is complemented by SmartSafe™ failsafe protection and the security of Spektrum QuickConnect™ technology that provides lightning-fast reconnection in the event of a low-voltage brownout.

NOTE: The AR400 receiver is not compatible with the original DX6 DSM park flyer radios, not to be confused with the newer DX6 DSMX full range radios
