Plug it into the USB port on a computer. Mine did the same thing but plugging it into the computer seemed to work. My tiny brain says it was charging too fast otherwise so it never fully charged. It charges slower on the computer but will always fully charge that way.My RC will charge to three lights then turns off. I retry and get the same thing. Without the charger connecter, when I turn it on, it
shows 3 lights. How do I make it fully charge?
