My Cheerson cx20 fell from 150 feet to the ground. I am rebuilding it onto a 450 frame. I have attached the original Cheerson ESC to the 450 PCB. How do I get power to my flight controller? It received power on the old Cheerson board.

So I thought I would answer my own question just in case anyone else needed help. I added a UBEC from the PCB into the Cheerson cx20 flight controller. I soldered the battery end of the UBEC directly to the soldered area for the main plug to the battery. The other end I simply plugged straight in to an open plug on my flight controller right next to all of the ESC plugs. I now have power to my flight controller and everything is working great. Converting my Cheerson cx20 to the 450 was the best thing I have done so far.
