It's hot as hell in Nevada. I can only fly 8 minutes without the screen going completely dark on the iPhone. I'm waiting for a new Smart Controller which hopefully will solve the issue. Don't want to buy one now only to have them release a new one in three months. I can only fly very early in the morning - under 90˚- or very late, almost dark which can still be a problem when it's 103 degrees at 7PM. Two weeks ago I tried to shoot my grandsons cliff jumping at the Colorado River and by the time we go up to the top, the screen was gone. What a pain.
