I have a new problem with my P3P controller. When I try to power it up now, the left most led does not ligtht at all and the other four light up for about three seconds and then go dead. The battery is charged and shut when I charged it. Nothing I have tried works. UPDATE: I went ahead and opened the controller and found the battery was swollen and apparently not able to provide enough current to keep the controller active. Thanks for the replies, After many flights, I know that it turns on with one push followed by a second just like the quad. But thanks for the suggestions! Now off to find a replacement battery.
