194 flights with my P4, 30 hours and 25 minutes. Everything OK with the exception of weak transmission signal and iPad mini4 screen not receiving well the video signal since a couple of months ago. This never happened before until last new updates, and I have tested in several occasions that this is happening to me only when ambient temperature goes 30 degrees Celsius or higher ( 86 Farenheit). IPad case gets really high, probably due to extra processing which was not as demanding on previous software versions.
