Spektrum AR631+ 6 Channel AS3X+ & SAFE RC Receiver - SPM-1031

The Spektrum AR631+ is a 6 channel full-range receiver with AS3X+ and SAFE flight stabilisation, built for fixed-wing RC aircraft running Spektrum DSMX and DSM2 transmitters. Part number SPM-1031, this RC receiver combines a stabilisation system and standard receiver in one compact unit, so you can add gyro-assisted flight or beginner-friendly safety modes without bolting on a separate flight controller. AS3X+ smooths out wind and turbulence for steadier flight, while SAFE technology adds self-levelling and bank-angle limits that make a plane far more forgiving for newer pilots. It suits everyone from first-time flyers using SAFE through to experienced pilots who want clean, locked-in handling with AS3X+ alone.
