AR631+ 6 Channel AS3X+ & SAFE Receiver

Spektrum AR631+ 6-channel AS3X+ and SAFE receiver

The AR631+ is the AR631 with the new AS3X+ stabilisation and Smart Transmitter File Download. AS3X+ counters wind, turbulence and other external forces, so the plane flies smoothly and precisely – no delay in the controls, no limit on control surface throws. SAFE limits bank and pitch angles, so the plane does not end up in extreme attitudes.

Six channels, DSMX with DSM2 compatibility and an extra-long 230 mm antenna (approx. 9"), which lets you mount the receiver in tight spots and still get the antenna clear of batteries and ESC – keep it at least 75 mm (approx. 3") away. AS3X+ and SAFE are set up via Forward Programming directly from your Spektrum transmitter, and the throttle port (channel 1) automatically detects a Smart ESC and sends current, voltage, temperature and RPM to the transmitter.
