I'm building a quadcopter and have discovered that most ESC have a built-in BEC, but I was wondering if it wouldn't be better to use only one.
What if I delivered power to my four ESC with a unique BEC ? Would that work ? I think this would be easier to configure (you have to set it up only once for the four ESC) and it would prevent each ESC from having it's own behavior.
Am I doing it wrong ?
Here is an image of what I'm talking about :

Given the answer by Ian McMahon it appears that this schema is not the right thing to do, since I had misunderstood the role of BECs.
So would the right schema would look like this ? Edit : trying to find the original image and upload it. I'm still not sure if I'm getting it.
Do I need 4 ESCs with integrated BECs and connect all three cables to flight controller ?
