So I recently purchased this 40amp ESC from amazon because my 4-in-1 broke and while searching I noticed some of the ESC's online only had two cabes (black and white) on their servo cable plug thing. I was wondering why their are only two. Also, I was wondering if my ESC supposedly has BEC, if it automatically supplys the said voltage to the FC, and if I have 4 ESC's with BEC, does it still only give the said voltage. Finally, if I wanted to control a servo via APM, is BEC required?
Thanks in advance!
