The landing gear was beefed up, that was nice. You could see the camera wires hanging out of each one. DJI sent me a email before the end of the year and asked me to go to a link to answer some questions on what I would like to see if another new model came out. I can see the quads shown here had sensors on all sides which would go along with a couple of the questions I was asked. Basically, you can be flying towards the side of your house, a brick wall, a tree, and the sensors will stop the unit from crashing. Can't wait for this new setup. I'm ready to pay, get on a list, whatever I'm ready for this new technology that is out now.
