When sending an item into our service center we ask that you:

    This web page also includes estimated service turnaround times as well as a link to check the status of your repair.

If the replacement part we are sending you is on back order, you can follow the status by periodically checking the product page. Unless the stock status reads "In Stock", then availability has not changed.

Items that are discontinued are no longer in production. We apologize for the inconvenience. It may be worth checking a third party online retailer or used hobby markets for these items.

  • You will need the SPMA3065 PC programming cable and online PC Spektrum program application.
  • Cable and software can be found here.
  • Sign into your spektrumrc.com account from the Program and connect the receiver to the Programming Cable. The PC application will display the serial number and allow you to register and update the firmware directly within the application

You will need to send a picture of the serial number to our product support staff. We will reach out to the original owner for permission. If we do not hear from them in 30 days, at that time we can deregister the transmitter.

Check out our Comprehensive video tutorial on YouTube that walks you through the entire process of setting up your AR637T Receiver.

  • A serial number will be emailed to you as part of your purchase receipt.
  • If you do not receive an email with 24 business hours, please check your spam folders.

  • No, if your computer is connected to the internet then it will register and activate automatically.

Using a computer with internet access visit http://activation.knifeedge.com/RealFlight9/ and enter your serial number and activation key from the install process. An activation code will be generated which will need to be entered in to Product Activation screen.
