Understanding logs ESC instances

I was reviewing the log of my drone, and the FCU used is Matek H743 BDShot. While going through the logs, I noticed that there are 5 instances of the Electronic Speed Controller (ESC), as shown in the picture below. However, I only have 4 motors connected. Why am I getting 5 instances of the ESC, and why do all of them have data and RPM values? Am I missing something? @andyp1per

ESC[0 … 3] are your 4 instances.
Ignore ESC

Thanks @amilcarlucas. So what does ESC signify then?

Its just an artifact of how mavproxy does it - you won’t see these in mission planner
