I flew two 13-min flights with my P3 Pro on SEP 20th using an iPad Air 2 with iOS 9.0 installed. The P3 Pro flew very stably with VPS system, compass, GPS, flight controls, and telemetry all working well and accurately. Although my HD video was rock stable (using Custom Channel 20 with 4 Mbps video transmission rate) out to 7900 feet distance from Home Point, I did get "Weak RC Signal" starting at 5000 feet distance at a location where I have flown out as far as 11,000 feet multiple times in the past in similar temperature and weather conditions before losing RC signal. I had no problem maintaining HD image quality and signal strength (4-5 bars) out to 7900 feet, but the RC signal strength was down to 1-2 bars at that distance, so I turned aircraft around and returned home. But two data points is not enough to make a definitive evaluation of whether this is a change in performance due to iOS 9.0 upgrade or local signal interference. Note: the RC antennae were perpendicular to ground, parallel to one another with wide flat sides kept facing the P3 Pro throughout the flight.
I did note one anomaly (bug) in DJI GO software performance under iOS 9.0. When playing back Flight Records, the Red Arrow aircraft symbol never moves from the Home Point, although it does rotate to show the correct aircraft flight direction. Previously, the Red Arrow aircraft symbol would trace the aircraft flight path at the advancing end of the yellow highlighted flight progress path. |
