Spektrum AR637T+ 6-Channel Telemetry Receiver Overview

The Spektrum™ AR637T+ 6-Channel AS3X+ Telemetry Receiver is a DSM2® and DSMX® capable receiver with a compact design that fits a variety of aircraft. The full-range receiver features integrated AS3X+® and SAFE® stabilization and provides better flight performance, improved sensor accuracy and increased data rate with the all-new AS3X+ stabilization algorithm, giving pilots a completely different flying experience compared to AS3X. There is no delay in control response, nor is there a limit to rudder deflection. You will simply have the feeling of flying an expertly tuned model that does exactly what you want it to do.
AS3X+ and SAFE are tuned and set up directly from your Spektrum transmitter* with simple 3-step forward programming. To use SAFE and AS3X+ technology with the AR637T+ receiver, the receiver must be programmed with a compatible Spektrum transmitter. With Forward Programming, no apps or cables are required to program or make changes at the flying site.
The AR637T+ features full-range telemetry and an integrated barometer to provide altitude and vario telemetry data without the need for additional sensors. XBUS, RPM, voltage and temperature sensor ports can be used to utilize additional telemetry sensors that are sold separately. It also features an SRXL2 connector for a separately available SRXL2 satellite receiver (SPM9747) to benefit from additional RF redundancy. An SRXL2/Bind/Programmer/Battery and Servo Slot side connector panel is built in to connect smart devices, program and update the receiver, bind it with a conventional bind plug or connect a battery. The AR637T+ also features a bind button for easy binding without a bind plug and offers SmartSafe™ technology as well as hold-load command and other failsafe types that can be set through forward programming. In addition, Smart Transmitter files can be used to store BNF models on the receiver to automatically apply programming when binding the model.
Please note: The Spektrum DX7S and DX8 Gen 1 transmitters do not display altitude or variometer telemetry with the AR637T+ receiver.
These transmitters do not support forward programming components: DX6i, DX6G2 (EU version), DX7, DX7S, DX7SE, DX7G2 (EU version), DX8, non-computer transmitters.

Spektrum AS3X+ Receiver Firmware Update Guide

Spektrum AR637T+ 6-Channel Receiver Features

• AS3X+ and SAFE are programmed directly from your Spektrum transmitter using Forward Programming*
• Bind button enables easy binding and eliminates the need for bind plugs
• Optimized design with servo connector header in a lightweight housing
• Connectors for use with SRXL2 satellite receivers and telemetry sensors
• Standard servo connectors

NEXT LEVEL FLIGHT STABILIZATION
The all-new AS3X+ features a significantly improved stabilization algorithm that has been thoroughly tested by experts with extensive model flying experience. The system is even easier to tune and can be easily optimized and set up for any of your aircraft types. Never again spend hours tuning and optimizing until you find the settings for your model. We were able to program most aircraft in less than 5 minutes, including tuning for the first flight.

Key improvements to the AS3X+ include:
• Snap and release value parameters
• Heading hold improvements
• Improved gyro filtering
• Support for canard and thrust vector control

SUPPORT FOR SMART TRANSMITTER FILES
Smart transmitter files are a new feature on the AR637T+ receiver that makes transmitter programming easier than ever. They consist of a set of transmitter configuration parameters stored in the model file in the receiver. When binding to a receiver that contains one of these model files, the user can choose to download said model file from the receiver and overwrite the currently selected transmitter model memory with the model file stored on the receiver. This provides the user with an easy way to import a new model setup for their BNF model into the current model memory without having to program the model themselves or search for and download the relevant model programming online.
Note: Supported transmitters are currently the iX20, iX14 and NX transmitters with the latest firmware updates.

FORWARD PROGRAMMING
You can wirelessly configure the AR637T+ receiver directly from any compatible Spektrum™ transmitter via Forward Programming. No separate computer or mobile device is required for setup and customization.

SAFE® TECHNOLOGY
SAFE® (Sensor Assisted Flight Envelope) flight mode helps pilots avoid over-controlling their models. SAFE uses AS3X+ to achieve normal flight performance, but with limited bank angles to prevent the aircraft from entering extreme flight envelopes.

SMART TELEMETRY
Use the AR637T+ receiver with a Smart ESC and a telemetry-enabled Spektrum DSMX® transmitter to take full advantage of Smart™ technology. Important telemetry data such as current, voltage, temperature and RPM are sent directly to your transmitter in real time. For more information on Smart Technology, visit our Spektrum Smart Technology page.

INTEGRATED BAROMETER
The Spektrum™ AR637T+ receiver features an integrated barometer (built-in pressure sensor) to provide altitude and vario telemetry data without the need to purchase additional sensor modules.

SAFE® PANIC BUTTON FUNCTION
Sometimes referred to as a rescue function, the panic button is a momentary, push-button SAFE stabilization that returns the aircraft to level flight from any attitude. The push button is normally used for this purpose.
