Dumb newbie question. My Mini 4 takes off and I set it at 50 feet and fly towards an almost cliff, about a 400 ft change in elevation. The Mini 4 recognizes the obstacle and the avoidance mechanism take over and the drone rises to avoid the cliff. How far from the cliff does the avoidance mechanism take over? How high will it rise and once over the cliff what elevation will it fly at? Or do I have to fly it over the cliff and adjust the elevation with the controller? Same scenario with a tall pine tree?
