Been having problems while flying, from 100% it drops to 0 and starts to return home, definitely not the controller, can anyone help me with this situation. Also it does this while it’s just idling and in flight[/QUOTE
I rarely pushed my P3S very far, maybe 500-600 feet at most. Didn't need to go further till recently and realized I was losing signal beyond 500 feet. Sent it in to DJI and they sent me a new RC and P3S. All repairs were covered under warranty.
I don't know if was always like that or if one of the updates caused some damage. I was extremely pleased with their service. Had it back inside a week.
So if you're sure it's not the RC, then you may need a new main board.
