Apologies if this has been posted before. I'm new here and didn't read every thread so . . . My phone (LG Stylo 2) wears a rugged armored case that is necessary due to the fact that I destroy phones on a regular basis without them. I'm just not that careful with them. Whatever. But, my Spark controller couldn't hold this phone because the phone in it's case is too thick. I'm not going to remove and replace the case every time I want to fly my drone so I did a little mod on the controller's arms. I just removed one of the little rubber "grabbers" inside the arms and the phone now fits perfectly. Remove these three little screws and the little "grabbers" slide out of the ends of the arms. I initially removed both from each arm, but then realized I could use one on each side. Works like a charm. Using a tiny little Torx driver, remove these three screws and slide the "grabbers" up and out. I'd show a pic of the controller with the phone mounted but my phone is my camera so I can't.
