I got my Q500+ from DronePros thru Amazon @ the first week in April. I have had my ST10+ lose signal and video when I flew her from my house at the top of a cul de sac to the entry, no more than 200 feet away. The screen goes black and the pop up on the screen is the same as when I initialize the ST10+. Now the aircraft remains in the air and if I am recording video, i see no interruption on the SD card. The ST10+ will reconnect in approximately 10 to 15 seconds, but I don't like that temporary loss of connection. Have any of you experienced anything like this?
