Hi, P2 with Gimbal is up an running. The new box of toys has arrived: AVL58 Datalink (for future use with Ground Station) iosd mini Lilliput 663 for FPV. I can just about figure out how to connect all the data oriented cables (I think). BUT: At the Ground End, what and how, specifically, to I get power to: 1. DataLink and 2. AVL RX? The docs keep referring to a battery -- what battery? Can I hook them up somehow to the RC Unit? Do I need to go buy something? If so -- what??? H-E-L-P (and yes, I am a rookie). s.
