Every inch of the Mavic Air is a testament to thoughtful engineering. Before handing off a review unit, a DJI rep takes us through the process of getting up and running. He flips open the smartphone docking arms from the bottom of the remote, revealing two hidden replacement joysticks nestled inside.

Getting the Air up and running feels a little like solving a 3D puzzle. The drone maker has crammed so much into so little space here, it’s a constant process of flipping, twisting, removing and inserting to get the thing operational. It’s all a very clever feat of industrial design and engineering, but none of it is particularly intuitive.
