Single ESC's
GetFPV is home to many different electronic speed controllers. Single ESC's are typically mounted on each arm of your drone, one for each motor. Single ESC's are perfect for quads that don't have a lot of space in the center of the frame (electronics stack). Drone racers tend to fly single ESCs because, after a crash or a burnt up ESC, they only have to replace one, not an entire 4-in-1 or stack.
