The Spektrum AR637T+ 6-Channel Receiver combines next-generation AS3X+ stabilization, SAFE flight envelope technology, and full telemetry in a compact, lightweight receiver for RC aircraft. Compatible with DSMX and DSM2, the AR637T+ offers pilots precise, responsive, and stable flight across a wide range of models.

Featuring Forward Programming, you can configure AS3X+ and SAFE settings directly from your Spektrum transmitter without the need for apps or cables. The all-new AS3X+ algorithm provides improved sensor accuracy, faster response, and better control feel, giving your aircraft an expertly tuned performance right out of the box.

The AR637T+ also includes an integrated barometer for altitude and variometer telemetry, along with XBUS ports for additional telemetry sensors, an SRXL2 port for RF redundancy, and Smart Transmitter Model File support to simplify BNF model setup. Built-in SmartSafe™ technology and panic recovery help prevent crashes, making it ideal for both advanced pilots and those looking for an extra safety net.
