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.

- 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-SPMA3065 or Audio-Interface AS3X Receiver Programming Cable-SPMA3081 (sold separately) for programming
- Convenient Bluetooth Module available for wireless connection between AS3X Programming app and AS3X Receiver (SPMBT1000)

Products: Spektrum™ SPMAR7350 and SPMAR9350 receivers with PID numbers beginning with TRA. This bulletin only applies to receivers with PID number starting with TRA. Receivers with a different PID number are not affected.

Issue: If you connect a temperature sensor to the receiver and the temperature sensor reaches 110°F, the receiver will shut down.

What To Do: Please visit http://spektrumrc.cachefly.net/apps/updater_instructions.html to update your receiver firmware. You will need a Spektrum USB Transmitter/Receiver Programming Cable (SPMA3065) to complete the update.


Finding the PID number:

The PID number is a manufactured identification number located on the product box as well as on the bottom of the receiver.

Corrective Action:

  1. If you have not already, register your Spektrum receiver at www.spektrumrc.com.

  2. Connect your receiver to your computer using the Spektrum USB Transmitter/Receiver Programming Cable (SPMA3065).

  3. Visit https://spektrumrc.cachefly.net/apps/updater_instructions.html to update your receiver firmware.

  4. Follow the instructions listed under Spektrum Updater.
