My p4 is at 84 feet height altitude, my rth is set at 50 meters (164 ft). My drone is not facing the sun. Upon engaging the rth, my p4 ascended to the maximum height of 394 feet and just hovered. I waited a few seconds but it seemed like it will not come home. I wouldn’t have known if I waited longer if it will actually come back if I hadn’t cancelled rth and just flew her back though. Gladly, she’s in line of sight. I will do my best to upload the log as I’m so ignorant on how to figure that out. Tried before my previous post but failed. I’m sure that if that happened while she far away, I wouldn’t see her again.
