Exclusive Spektrum AS3X+ technology enhances flight stability by countering the effects of wind, turbulence, and other outside forces to help your aircraft fly smoothly and with precision. You'll feel like you're piloting an expertly tuned model that performs exactly as you want.

SAFE (Sensor Assisted Flight Envelope) technology flight modes help pilots avoid over-controlling their models. SAFE uses AS3X+ to deliver normal flight performance, but with limited bank and pitch angles to prevent the aircraft from getting in extreme attitudes.

The AR631+ features an extra-long 230mm 2.4ghz antenna (approximately 9 inches), specifically engineered for use in tight installations. When installing your receiver into an aircraft where there is less then ideal space away from batteries and other devices, a long antenna is key. This allows users to install the receiver in tight spaces and isolate the antenna for optimal reception and link quality. When positioning your antenna, it is best to have it at least 75mm ( approximately 3 inches) away from batteries, electronic speed controls (ESC), ignition systems, and other electronic devices. Use the integrated flight log telemetry to perform a through range test to better evaluate your setup.

You can configure the AR631+ receiver wirelessly, directly from any compatible Spektrum transmitter, through the Forward Programming menu. No separate computer or mobile device is needed for setup and adjustments.

To enjoy the full benefits of Smart technology, use the AR631+ receiver with a Smart ESC and telemetry capable Spektrum DSMX transmitter. The AR631+ features fly-by telemetry and will provide vital telemetry data such as current, voltage, temperature and RPM is sent directly to your transmitter. The AR631+ is not compatible with Spektrum telemetry sensors. For more information on Smart Technology please visit our Spektrum Smart Technology page.
