A new generation of Spektrum™ AS3X® (Artificial Stabilization – 3-aXis) receivers is about to make it easier than ever for fixed wing pilots to transform their flying experience with this amazing technology. Like their predecessors, they combine AS3X technology with a DSMX® receiver in a single unit. What sets them apart is programming software that makes setup and adjustment of their AS3X settings much easier.

The software’s easy-to-understand, graphical user interface will allow pilots to:
- Select which AS3X mode to fly with: Off, Conventional Rate and Heading Hold
- Activate flaperon/dual aileron, delta/elevon, V-tail or dual elevator mixing
- Take advantage of servo setup options like balancing, travel adjust, absolute limits, reversing and more
- Map output and gain settings for individual channels
- Programming made easy via PC or iOS/Android mobile devices
- Uses AS3X Programming Cable or Audio-Interface AS3X Receiver Programming Cable (sold separately) for programming
- Convenient Bluetooth Module available for wireless connection between AS3X Programming app and AS3X Receiver (SPMBT1000)

In order to activate AS3X technology in a Spektrum AS3X receiver (AR636, AR6335, AR7350 & AR9359), you must program the receiver using the AS3X mobile programming application. Until AS3X is activated, the receiver will operate as a standard DSMX aircraft receiver and will not provide electronic stabilization enhancements. For more information on programming a Spektrum AS3X receiver (AR636, AR6335, AR7350 & AR9359), please visit www.SpektrumRC.com/AS3X

Android and Spektrum iX12 users please note, due to the changing nature of Android FSK modulation, the audio programming cable (SPMA3081) no longer functions with those devices. The best interface for all devices is the Spektrum Bluetooth Module (SPMBT1000). It is faster, more reliable of a connection and you can simply leave it plugged into your receivers and access when you need to make changes.

It sounds like you may have flashed the receiver to an open-stock configuration, with no specific model file. Try reloading the EC-1500 model file, which is located here: https://bit.ly/3Bv6cWX

Some AR636s installed in BNBF Basic airplanes had SAFE Select, an optional feature similar to Beginner Mode (bank angle limits and self leveling). Open stock AR636 receivers do not offer SAFE.

Generally speaking, origin is the difference between AR636, AR636A, and AR636B. Which is to say, which BNF Basic airplane they were installed in. Some versions of AR636 can not be reprogrammed. No versions of the AR636 series support Forward Programming.
