I was flying my Spark with my phone, but I had an iPad Mini 2 which fit on an Mavic Air controller just fine, but the grips on the Spark would not open quite wide enough. So I used my side grinder and trimmed back the restricting plastic just a bit on each side of the remote control and voila! the iPad Mini 2 fits nicely. A small Dremel tool would work well as I did scratch up the side of my remote a bit with the bigger grinder, but it is strictly a cosmetic problem only.
