I have the 3 4k, and after the controller would not turn on, or charge, I found a guy on Ytube that had and easy fix. Open it up, unplug the battery and plug it back in. Works like a charm. Only what I want to know is why it shut down like it did. Some say over charge fail safe. Others say bad battery. Does anyone know? If it's an over charge fail safe I'm ok with opening the controller up now and then, but a battery issue could be an in flight disaster. Thanks for any info and KEEP FLYIN!!
