Hello
I own the Phantom 3 professional and I upgraded to version 1.3.20 firmweare.
After a while 'flying remote control completely lose the signal for a few seconds and returns home the phantom. Before it had never happened, what should I do?
Thank you

In effect the settings have been the same, so what should I check? because there is complete loss of the remote control signal

Did you actually get a red LED on the remote?

that's pretty usual. probably your environment is not so good for the flight , or has a lot of interference. so its a good news that it get auto RTH

Thank god for RTH . Lost connection once , about 700m from home . My knees went weak , then RTH engage itself . Oh the sweet sound of 4 propellers beating the air getting louder as the Phantom was coming home .

You should calibrate the IMU, gimbal and compass. Especially the IMU and gimbal after all updates. Search the site for instructions if you need further clarification. Lot's of discussion on this topic already exist.
