Amazingly I was all set to write how much I do not like the “Heath Robinson” Mavic controller that works with the iPhone when DJI decided to bring out a dedicated Smart Controller.
When you arrive at your position it takes forever to setup the controller making sure you have the lightening connector correctly positioned then scrunching the phone into position and lastly showing the iPhone X your face this all takes a horrendous amount of time.
The wiring from the controller to the iPhone is definitely a weak spot and the iPhone perched on two rubberised posts is asking for trouble.
Now this looks a lot better and your not relying on an Apple iPhone, scrunched either side. Plus DJI claim its twice the brightness of a smartphone so viewing the live feed should be far better. At £579 its not cheap but for budding pilots like me its well worth the money.
