Hi has anyone experience this? I wanted to my phantom 4 to fly waypoints. So i record my way points preflight using the apps. When i went to fly it. It move like 1 kph at an altitude of 500m. When i realize its not gonna even make it to the second waypoint i press go home button and it when home but because it when to an altitude of 500m it took a long time to come down and it came down longer than usual. So i phantom came crashing down at midair and was completely destroyed.
