Description
Built in AS3X Stabilization System with SAFE flight envelope protection
AS3X and SAFE set up through forward programming directly from your Spektrum transmitter
Ready to use with Spektrum Smart ESC for one-wire telemetry data without the need of modules, links and wires
Streamlined, end-pin design in a light weight hard-case
Bind button allows for easy binding and eliminates the need for bind plug
DSMX protocol receiver with DSM2 backwards compatibility
Fly-by range telemetry support
Standard servo connectors
With Smart Technology the normal servo connector delivers the throttle signal to the ESC, plus the ESC can send telemetry data like voltage and current back to the receiver. The AR631 receiver throttle port (Channel 1 port only) will automatically detect when a Smart compatible ESC is connected. ESCs with Smart and IC series connectors can also pass along battery data from compatible Spektrum Smart batteries. Spektrum Avian ESCs are compatible with the AR631 receiver for Smart Technology features.
For Smart to function you must have a Smart ESC paired with a Smart telemetry receiver, and a Spektrum DSMX transmitter with telemetry. An update for your transmitter may be required for Smart features. See the Spektrum website to register and update your transmitter. If a standard ESC or servo is plugged into the throttle port on the AR631 receiver, the throttle port will operate normally (PWM signal) like any conventional RC system.
AS3X Technology
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 Technology
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.
Long 230mm 2.4GHz Antenna
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.
Forward Programming
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.
Smart Telemetry
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.
