Took the Razor out to see how the Spark would do. Needless to say, I needed an air compressor to clean it out afterward. Very windy on the boat but the little spark kept tracking pretty well! Landing on the bow of the boat was tricky (and scary)!
I wonder if your app froze on your tablet. If it happens again, double press the home button on your iPad and close out. Then reopen the app and see if it works. Could be some sort of conflict.
Yeah, that one turned out amazing. Love the three colors of the water. I don't even know what I'm doing so that says something about the Sparks capabilities!
