The drone WILL NOT hover in place. It drifts left always, perhaps 50-feet, and GPS brings it back, then it drifts again. It is not being carried by the wind, but it seems to have a mind of its own. It is impossible to bring it straight down and land smoothly because it is always moving left or right as you descend. I have home location established and 10 satellites. It is also brand new. I have had a phantom 2 vision, and the vision plus is new. I have calibrated compass, controller and drone. All software up to date. I think it is defective. Any ideas?
