AR631+ 6 Channel AS3X+ & SAFE Receiver

AR631+ 6-Channel AS3X+ & SAFE Receiver is a compact DSMX receiver that brings AS3X+ stabilization and SAFE flight envelope protection to model aircraft. It helps counter wind and turbulence, delivering smoother, more controllable flight and making handling feel more stable and reliable.

Designed to work with Spektrum DSMX transmitters, this receiver features a bind button for quick pairing, supports wireless Forward Programming, and uses a long 230mm 2.4GHz antenna for flexible installation. It also offers fly-by telemetry and, when paired with a Smart ESC and a telemetry-capable transmitter, enables Smart Telemetry to report data such as voltage, current, temperature, and RPM back to the transmitter; with a standard ESC the throttle port operates normally in PWM mode. The AR631+ is compatible with Spektrum Avian ESCs for Smart features and is not recommended for turbine-powered aircraft.
