Even better, spherical collision avoidance, like a bubble around the aircraft.
Radar, I believe it's called.
As much as I may be tempted to trade up or simply add another quad to the collection, I just got an Inspire 1 a month ago and will be paying that off for some time now.
The big negative with getting a P4 for me would be the need for a third type of battery, buying ($159 or $169?) spare batteries, and it using a different charger.
Can't dji standardize the batteries somewhat? Will the Phantom 5 also have its own different battery?
Then again, Phantom 3 batteries should be getting much cheaper soon.....
