I have noticed that since I did the firmware upgrade and app upgrade I have been having lots of lag, and video freezing and cutting out. Before the new app and e new frimware I could fly out 2 miles on stock setup with no problems but now I'm only getting out 2000' or so and I get video freezing and cutting out. I also noticed I drift when I'm hovering at 10 feet. I have the controller version A and I did both upgrade the controller and the bird. Anybody else having those issues or anybody got a fix?
