Reversing Motor Direction - Reverse Radio Button
Getting my ESC setup and got to the step where I check motor spin direction. Two of the motors need to be reversed, so I went to the Servo Output menu and clicked the "reverse" radio button. Seems pretty intuitive, and also aligns with this Ardupilot Youtube video saying to do the same: Part 1 - Hardware and Setup: Complete ArduPilot Tuning Guide (ArduCopter).
However, this did nothing to change the motor direction, and after some further digging, it appears my two options are to swap any two motor wires, or change the direction through the AM32 Configurator software.
My question is: why are these reverse buttons in this menu to begin with if they don't actually work? Did they used to work in the past and that's why it was also recommended in the Youtube video above?
I'm trying to understand the setup at a slightly deeper level than surface level, and I'm wondering what the thought process is having these reverse buttons available and if they are possibly legacy buttons that need additional footnotes within the software to help avoid confusion.
