This thread is to track all the known issues with the Phantom 2 in one place. Last updated 18 June 2014. Compass Declination Defect - Cause identified, beta software in test. Description: Curving and hooking, unable to fly straight, course lock deviation experienced by flyers in areas of high magnetic declination. Status: Beta testers have been evaluating the 3.05 beta firmware and sending data to DJI for analysis. Consensus is the beta fixes about 80% of the problem. A second beta will hopefully be issued by 20 Jun 2014. More information: viewtopic.php?f=19&t=10317 - Mid-Flight Shutdown - Cause unknown, no solution, no workaround. Description: The Phantom will simply shut down in the middle of flight resulting in a uncontrolled fall and crash. Cause unknown. No known solution. This is not to be confused with VRS. There are two variations of this issue. The "power on" version where the Phantom motors power down to idle or less. The "power off" version is a total loss of power across the Phantom in mid-flight. Status: Some incidents have been traced to cold solder joints. A safety circuit in the battery is suspect in the "power off" version. No acknowledgement as yet from DJI. No known defective batteries sent to DJI. More information: viewtopic.php?f=19&t=16801 - Premature Autoland - Cause unknown, no solution, no workaround. Description: The Phantom will initiate an autoland sequence earlier than expected and is not consistent. Normally the autoland function only kicks in when the voltage falls below 10.7v which is normally below 15% remaining. Status: There are about 12 users reporting the same issue, there is no known cause or workaround. More information: viewtopic.php?f=19&t=17324 - Un-commanded Yaw with the H3-3D Gimbal - Cause unknown, no solution, possible workarounds to be explored. Description: The Phantom 2 with the Zenmuse H3-3D gimbal suffers from intermittent un-commanded yaw. It is most noticeable during descent. An exploration into the gain settings has been undertaken to see if they can help or even eliminate the issue. Status: Early exploration into the issue. No conclusive information as yet. More information: viewtopic.php?f=19&t=14325&start=30 - Incorrect No FLY Zone Assignments - Not fixed. No workarounds. Description: Some small airports are deemed as group A and even smaller ones group B while some big ones are left out. - Zenmuse H3-3D Compass Calibration Freakout - Not fixed. No workarounds. Description: The Zenmuse H3-3D gimbal jams and generally goes bezerk when you calibrate the compass. - Loss of Horizontal Control During Vertical Descent - Fixed in v3.04. Description: The Phantom stops responding to elevator and aileron when descending at max rate (2.0m/s) under firmware 3.02. Fixed in v3.04.
