Help the almost helpless. I am very new to this but want to extend my photography abilities.I purchased a second hand quad running a Naza lite controller and Tabot gimbal which I run off the balance cable from a 4s battery. I have purchased a Fatshark Predator for FPV (of course). Since I have the Tabot running from the balance cable how do I power the FVP? Thanks in anticipation of solving my problem and although I may (or may not) sound like I know something I don't, so please keep it simple and in plain English with instructions a 5 year old can follow. Cheers.
