I have been flying for a couple days and I noticed that one of my motors stutters during start up, but when I take off it seems to work just fine. Do I have a bad motor or esc board? I also notice it gives off a high pitch noise. 2nd issue I have is one of the red lights in front flickers on and off like it doesn't have a solid connection and sometimes goes out completely. Any advice would be great.
