The Spektrum AR637T 6-Channel Receiver introduces a new level of connectivity, safety, and performance for fixed-wing RC pilots. Featuring SAFE® flight envelope protection, AS3X® 3-axis stabilisation, and full Smart™ telemetry, the AR637T is designed to deliver confidence and control across a wide range of aircraft, from electric park flyers to large petrol models.

Built around Spektrum Smart Technology, the AR637T allows seamless communication between your receiver, Smart ESC, battery, and compatible Spektrum transmitter. When paired with a Smart ESC, telemetry data such as voltage, current, temperature, RPM, altitude, and vario is transmitted via a single wire, eliminating the need for additional sensors, modules, or wiring.

Both AS3X and SAFE are configured directly from your compatible Spektrum transmitter using Forward Programming, meaning no apps, computers, or cables are required at the flying field. SAFE flight modes help prevent over-control by limiting bank and pitch angles, while SAFE Panic Recovery can instantly return the model to level flight at the press of a button.

The AR637T also features an integrated barometer, providing altitude and vario telemetry straight out of the box. Expansion ports allow connection of SRXL2 remote receivers and additional telemetry sensors for increased redundancy and system monitoring.
