I was flying today on a pretty new battery (just got it a week or so ago and only had 2 flights on it). I wasn't going too crazy in terms of speed (never full throttle) and was more or less just easing it out there and once I reached around 2200 feet or so away, it started giving disconnect type errors but it came back again a few seconds later. When I started to get this message as well as a few other errors (iirc, video signal lost, rc signal lost) I turned back. I also got an error message stating that it was switched to ATTI mode (which is fine as I'm comfortable flying in ATTI) but then changed back to GPS again. As I was turning back to return, I got disconnected again (3rd time i believe) and at that point it didn't come back again for a few minutes. I pushed RTH and the RC made the expected beeps for RTH engagement. I was happy to see a minute or so later that it was back. As it was coming down to home, connection was re-established and I took it out to RTH mode and just landed myself. I briefly considered going back up and continuing the flight since the battery still had plenty of charge left but decided not to tempt fate too much and just landed and pulled the battery and moved on to another battery. I flew on 2 more batteries and it was fine...no more problems. I did go and disconnect and reconnect the usb cable just to be safe. i am using an ipad mini 4 (cellular version but not actually subscribed to any cell service) connected to my phone's internet via wifi. healthydrones link: HealthyDrones.com - Innovative flight data analysis that matters Is it just a problem with distance? Is this pretty common?
