When it comes to what controller I prefer, I have a foot in both camps. I previously used my Android phone with my
M2P Controller; as my Gen 2 Apple iPad was not compatible with the DJI GO 4 app. Then one day my phone ran hot and the GO 4 app kept freezing while my drone was still flying, which really freaked me out. Soon after, and not wishing to have that experience again, I bought the
Smart Controller (
SC) which as others have already discussed now enables me to get into the air far quicker, is more convenient (no cable connection issues), has a bigger brighter screen than my phone; plus I have never experienced that freezing issue again.
Last year when my old iPad finally needed to be retired I replaced it with an iPad mini, and now I also use that with the original
M2P controller as a Secondary Controller to the
SC. The iPad allows me to run any Apple-only drone apps that the
SC cannot. I run this Secondary Controller setup as a “fail-safe” which can take over in case there are issues while I am flying with the Primary; plus it can be used by a photographer or other interested parties while the pilot in charge uses the
SC to focus on flying the drone. I have also used this setup to introduce new users to flying a drone, allowing a trainee to use the Secondary Controller to get a feel for the drone while the Primary Controller can be used to immediately take control back when the need arises.
In summary, I do like the bigger screen when using an iPad with the controller (versus a phone), but I much prefer to use the
SC for its convenience and reliability.
