I am using the latest firmware and on an iPad mini 2. Every flight results in random "No Signal ". Sometimes I can fly for 5 minutes, other times less than 2 min. I can still control the PH3 with the remote but all info to the app is n/a... Including the battery. I have to turn the drone off and then back on a few times to get it to get a signal again. Then it will give me the green "safe to fly GPS" and off I go. And again I will get 1 to 7 min of flight before I lose signal again. I have three batteries and it seems to get worse the longer I am flying. Really frustrating to loose the app mid flight. Any suggestions? Thanks.... New PH3 owner.
