You could easily reverse these so that the BEC is primary and the PLR5 is the backup. You can check in the ESC after a flight with a Jeti Box whether or not it had to draw from the BEC. I have turned on only the BEC side to verify it works, and it works great, but I like having the redundancy and a way to tell if it was ever used.

Basic ser up would be a PLR5 set to 6.8 volts while the BEC is set to 6.2 to draw current from the PLR5.
Is there any issue with one being linear and the other switching regulator?
