Because I am building a hex (or maybe a octopus) I want to understand and confirm that each motor requires a PWM output channel from the FC? So for a octocoper I would be using up 8 of the available 14 on the FC leaving me with 6 channels for grippers, camera gamble, etc.
Yep, that is exactly right! The remaining channels can be configured just as you desire. I believe we use PWM 14 or 13 for the taco holding servo in the course.
Also, I actually lol’d at your octopus line
