That looks great, One question for you, I am building my first Naza Mavic 4.1.  What does everyone doe for a PDB?  Do you use a small one or do you just build a power "web"?  since the PMU is running most everything?  I was looking for a small PDB with a built in BEC for the camera / extras but wanted to ask.  I have read a bunch of these and see very little on it other than the PDB in the BOM.  Thank you,
