Ok so I told my phantom 3 pro to run a waypoint sequence. It rose up , flew to starting point, flew straight up into overhead tree. My bad. Destroyed drone. Would the Phantom 4 avoidance system have stopped this straight up rise collision??
Probably would not have helped. Piloting requires that the operator does 99% of the avoiding. The systems currently integrated are designed to help in certain situations such as when the machine may be behind a building and it loses r/c connection. If it tries to fly RTH and the building is taller than the height, it may be able to avoid it. I'm sure you learned some of these lessons already - but the basics of a flying camera are that you don't "see what it can do" and test out features and/or just fly it around (in general). The reason is simple - this would be somewhat like steering a car into the tree to see if the airbag works. Every minute you put on your drone increases the chances of a mishaps. If you are at the point where you want to be familiar with how things work...best bet is extensive reading and then some testing in a large and wide open space. There are many things which could have caused such a crash as you describe. Your logs may show why - but if you were using a 3rd party piece of software, that may be another hint. Also, various scenarios are programmed into the drone which make it rise up quickly (RTH - so if it lost connection for some reason, etc.). If you don't have a warranty (extra cost crash warranty) you can still probably get a decent amount of money for various parts. Sorry to hear about your crash.
