It should work with the 3S wi-fi if you can use the DJI Go app, it comes with different pilots apps the DJI Go, the DJI Go4 and the DJI Pilot embedded into the android system
It acts like a android phone or tablet but more limited in some areas.
The only issue I see is the mounting on the 3s controller
Depending on the size of Crystalsky your going for , you might need to do something like this if your considering the 7.85in otherwise you probably don't need to drill
Didn't think it would work with a P3S. Now I'm tempted. Though at $599 for I can have a Galaxy S8 phone! (well, almost). The Ultra-Bright is $849 plus all the other stuff I would need to go along. Nevermind, I just talked myself out of it. :>
