A couple more things to check before we can be certain. leave the remotes where they are, but change channels with the problematic one. Does the problem persist? Also, change frequency.
If the issues persist with the same reciever, then it is likely the reciever.
One thing I would like to see is a debug mode/screen added to the Paul C Buff digital protocol (if not there already), CyberCommander, the Einstein, and elsewhere where possible, alongside a discovery mode.
Basically the purpose would be to capture any crash capture stack trace, and/or identify a reproducible sequence of steps leading to the issue, and/or eliminate the scenarios that work OK, in an automated or semi-auto manner. And save the info on the SD card. To resolve some bad crash cases the device could be put in debug mode to capture telemetry into a file on the SD card until crashes, at which point the card can be removed and the contents of the file emailed to you folks to significantly speed up and streamline this troubleshooting process.
