But as always if you find PID settings on the internet: they dont apply to every quad. You have to have a really similar setup than I do. Every quad is usually different. Many variables influence the outcome. But this can be a good startingpoint for you if you have simlar motors and ESCs...
I used a nice PDB (power distribution board) which has 2 switches for LED or VTX
So I can choose if I want my LEDs to be powered on with this easy switch.
I guess you can also hook up LEDs to be controlled by the NAZE32 board as well - but this is more advanced - the PDB is really easy.

You need a really small FPV cam for it to fit between the front booms!
I use the Fatshark 600TVL which as a really small housing. I even had to file it down on the side a bit for a good fit.You can tilt it a bit by using more double sided tape on the top of the cam holding frame than on the bottom. Works ok for me.

HD Cam:
initially made to mount the Mobius/runcamHD type of flat cams - but gopro or SJ5000+ in my case works also. Vibration dampening works really well - even wih unbalanced motors / Props I have no jello issues!
