**Frame:** Carbon fiber 250mm  

**Motors:** 2300Kv 2204  

**Power board:** Matek built in BEC’s 12V + 5V  

**FC:** CC3D  

**ESCs:** HLGRC 30A opto (no BEC)  

**Battery:** Turnigy Graphene 14V 75C 4S  

**Receiver:** Turnigy iA6B

My question is, this is the first time I’ll be using the opto on a drone. How do I power the FC without frying it, seeing as how there are no BECs on the ESCs?
