I was flying a photo shoot of tornado damage yesterday. The drone was about 1/4 mile from me when the radio controller went totally dead. The message said "RC not connected to your mobile device. The RC was totally dead after that. I unplugged the RC from the phone, tried to turn off the RC but it wasn't responding. Turned the phone off and then back on, but nothing. So, I'm standing there wondering how I'm going to get the drone back home, and in a few seconds I can hear it getting closer, and it lands right on the home point!!! Thank the LORD!!!! I've put the RC on the charger and there is no response. So, what do I do now. I purchased the bundle when Amazon had a sale last September. Obviously I could by a new RC, but any other suggestions are welcomed.
