Overview
The AR631 includes fly-by range telemetry and a bind button that makes it simple to bind without any plugs required and uses both SmartSafe technology and Hold Last in addition to pre-programmed failsafe types set through forward shows. A long 230mm 2.4gHz antenna, ideal for getting optimal reception when set up into tight areas. The AR631 also includes Smart Telemetry support.
With Smart Innovation the typical servo port delivers the throttle signal to the ESC, plus the ESC can send out telemetry information like voltage and existing back to the receiver. The AR631 receiver throttle port (Channel 1 port only) will automatically spot when a Smart suitable ESC is linked. ESCs with Smart and IC series adapters can also pass along battery information from suitable Spektrum Smart batteries. Spektrum Bird™ ESCs work with the AR631 receiver for Smart Innovation features.
For Smart to work you should have a Smart ESC coupled with a Smart telemetry receiver, and a Spektrum DSMX transmitter with telemetry. An upgrade for your transmitter may be needed for Smart features. See the Spektrum website to sign up and upgrade your transmitter. If a standard ESC or servo is plugged into the throttle port on the AR631 receiver, the throttle port will run typically (PWM signal) like any traditional RC system.

Please Note: These transmitters do not support Forward Setting devices: DX6i, DX6G2 (EU Version), DX7, DX7S, DX7SE, DX7G2 (EU Version), DX8, Non-computer transmitters

Long 230mm 2.4GHz Antenna

Long 230mm 2.4GHz Antenna
The AR631 includes an extra-long 230mm 2.4ghz antenna (around 9 inches), particularly engineered for usage in tight installations. When installing your receiver into an airplane where there is less then ideal space away from batteries and other devices, a long antenna is essential. This permits users to set up the receiver in tight areas and isolate the antenna for optimal reception and link quality. When positioning your antenna, it is best to have it at least 75mm ( around 3 inches) away from batteries, electronic speed controls (ESC), ignition systems, and other electronic devices. Utilize the incorporated flight log telemetry to carry out a through range test to much better assess your setup.
