ACCST D16 Compatibility – Firmware Downgrade

FrSky has now begun shipping R-XSR receivers with newer firmware, which is not compatible with many radio controllers running ACCST protocol firmware.

To downgrade the firmware, you will need to plug the R-XSR into a radio with an FPort (cable included with R-XSR) and downgrade using the firmware link below.
