While I understand there is obstacle avoidance in the new Phantom 4, there still is a need for Prop Guards. Hard landings/tipping, backing into obstacles, or small obstacles like wire/string may all be potential hazards. I do not see a place to mount prop guards on the new Phantom 4. The new LED under the motors appear to take up the old mounting points. Does anyone have any clarification on adding a prop guard? Better safe than sorry. Thanks. C.
