Review on PERGEAR Quadcopter Real Time Tracking Controller by Fernando Beck

Mine turns off when I'm over 200ft up or about 300-400ft away. Tried new cables. Flight without connection to the iPad. Try Android devices instead of iPad. New cables, different cables. A new controller and finally a brand new drone. It's not in beginner mode. Distance limit settings are irrelevant. The "Wifi-RC" switch doesn't matter. Reconnecting doesn't matter. Turning off my underground dog fence doesn't change anything. Checked for unusual magnetic fields, nothing. just typical suburban disturbances. In the "bubble" everything works fine. RTH recognizes the landing pad and lands right in the middle. The signal usually returns and I can cancel the RTH, but not always. Very discouraging. :(
