So I know a lot of you don't push the range limits on your P3s but that's one of the things I really enjoy. My phantom ran faultlessly up to 4 miles out before I did the latest DJI 1.4.0010 update alone with the iOS 9.1 apple update. Now I'm lucky if I can get close to thee miles. Has anyone else had this problem and reverted back to 1.3.20? I'm not saying it's the DJI update, it could well be the apple one but I'm wondering if anyone has gone back to the old firmware and if it has had positive results?
