Did you know that you’re supposed to register a drone with the FAA before you fly it? DJI knows this and made its Mini 4K drone weigh in at 249 grams to get around the rule. Right now, Amazon has the Mini 4K down to just $239 right now, which is the lowest price I have seen. The 4K camera sits on a 3-axis gimbal that keeps it extremely steady, even during high-speed flying. One of the best parts about this drone is the fact that it has access to all of DJI’s filmmaking tools.
