Got a Monster Patrol 27 mhz controller. It worked fine but now it doesn't respond once charged. Not sure if the kid blew the internal battery so I charged it w/button on, while on red the lights go for abit but once green it's dead as a door knob. New batterys in the controller and still nothing. Left it for a couple of days and still nothing. What should this lady do .... change the internal battery or something else. If I have to do the battery is there a tutorial for that on site?
