Hi,
I am building a quadrotor from the full kit provided by store.DIYDrones.com.
The power distribution board refers to a 5V out. Giving me the idea this thing runs on 5 volts...
when I first asked the sales team what batteries to buy, they sent me to some 3 cell 11.1V turnigy nanotech 2200mAh 45-60C discharge batteries.
I was surprised the kit doesn't seem to come with any kind of voltage regulator to bring 11.1 volts down to 5volts. Would this imply that the kit (motors, APM 2.5, etc.) are tolerant of a 11.1 volt supply?
OR, am I missing something like a voltage regulator, or possibly have purchased the wrong batteries?
Thanks for your help!

You were right that the electronics run on 5V, and you do need some form of regulated power supply.
The simplest method is to use one of the built in BEC's in the ESC's, but I personally don't like this and install a separate BEC connected to the main battery rail of the PDB.
The PDB's are setup to take the 5V from the ESC's BEC, if you look closely at the wiring diagrams in the Wiki.
