What else would you do with old tires but roll them off a desert cliff? Tried to make it from the tires point of view, but though it looked fast from the cliff, it didn't translate that way to video. Second part is in sport mode- nearly crashed into the cliff when the wind blew my hat off and I went after it instead of paying attention to the drone! Spark gets hard to see from on top- looked closer to the ground even on the phone than it really was. Anyway, enjoy
