Seems like the remote for my P3A won't "show" full charge. Had it on the charger for a good while and the lights at the bottom were still chasing. Booted up the craft and remote and it showed full charge. Is this normal? And..the remote won't update. I was using a reader they sent with the unit. My son is in IT and seems to think the reader is bad. Regardless, the remote refuses to update. It would just single beep then eventually turn off. I was apprehensive on removing the sd card or turning the remote off but, after 30 minutes, I decided it was safe. Tried again...same thing. Any clue why?
