Spektrum AR400 4-Channel DSMX RC Aircraft Receiver

The full-range Spektrum AR400 4-Channel DSMX RC Aircraft Receiver combines the speed and precision of DSMX control with the signal security of an active amplified antenna. This antenna is designed to enable 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 even in environments with heavy 2.4 GHz interference.
