One flight so far. Went back from the latest P3 Craft firmware to the previous version 1.3.2. No more FPV lag not even when turning around the craft, doing a 360 at distance. No more multiple random iPad Air 2 reboots. All signals are solid. I will fly the remaining 3 batteries and report back but I believe the latest firmware (1.4.2x) has issues. This is a night and day difference. My P3 is actually usable again like it was previously on firmware 1.3.2. Interesting tidbit. The intelligent modes still show in the GO App after you revert back to 1.3.2. The F-Mode switch works and brings them up. Each mode allows you to proceed to configure them but when you hit Apply the GO App merely answers with an error (function not found or enabled).
