Greetings, i'm not new to RC (i own many rc cars) but i'm new in drones. I have a drone with f450 clone frame and naza m v2 controller. i have some issues and i believe that the esc is giving me troubles. My drone specs are: F450 clone frame naza m v2 controller hobbywing (or hibbyking) 4in1 esc 1045 propellers sunnysky 2212 980kv motors storm32 gymbal i fly with 3s or 4s, mostly with 3s Anyway, i'm gonna buy the original dji f450 frame so i can solder the esc's direcly on the frame. But beeing noob i really don't know what esc's to buy. 30a? 40a? 50a? I see some options like opto or BEC but i dont really understand them So having that specs..what are the appropriate ecs to buy? what should i check first before i buy them? P.S. i really would like to buy ecs with the connectors built in cause i'm really bad at soldering Thanks a lot!
