Downloaded the latest firmware for the BB2. 4.0.6. decided to fly with the new tablet without the skycontroller. To my surprise it had much better range than the old mini ipad 1. If I moved while the drone was flying the distance indicator went way off. I landed within ten feet of me and it said it was 629 feet away. I discovered that the dead spot in the sky wasn't there anymore using just the tablet. That's a spot that the drone won't cross.
I went back and got the skycontroller and the distance measrement problem went away but the dead spot in the sky came back. That has something to do with the skycontroller. It's a place I usually don't fly at anyway.
