This applies to Vision and Vision+ owners too: viewtopic.php?f=19&t=16598 For those not familiar with the Compass Declination Defect If you live in: Western US and Canada Northeastern US and Canada Eastern OZ and all of NZ Northeastern South America Southern Africa This applies to you: Affects all P2x in areas of high magnetic declination (+/-8 or higher). Curved flight and hooking is worst when first flying. It improves during flight but may take several minutes. Once power is removed, the P2 forgets any adaptions it made during the previous flight. It appears to not affect the P1. Areas with very high declination will experience TBE during initial hover. Several people have returned their P2x thinking it was defective only to get a new one with the same problem. This is a firmware defect. Possibly a signing bug in the code. This defect is still present in versions 2.0 and 3.0 of the firmware. Measuring the angle between initial true heading and initial course lock heading will give you the real margin of error. Rotating the compass is not a recommended workaround. Using a very rough bottom up model, it is expected that at least 1 in 4 P2x users experience this problem. "Beta testers" have submitted data to DJI for analysis. We are waiting on DJI to provide us with an update.
