Ok, so they are happening across the board then. Has anyone tracked the flyaways based on firmware version?
Hi, welcome to the forum.
The version differences are not electronic - they are mechanical.
A-B Change of carbon fiber weave
B-C Supply of QR props
C-D Slightly redesigned landing gear mechanism (2 parts instead of 4)

Well DJI do when they analyze the flight log data.
I'd be curious to see the data for the number of flyaways on various firmware and various versions of the platform. Even if the changes from A-D are all mechanical, I think the information would be valuable.
Hi, I'm sorry for your loss, I myself crashed my inspire 1 (my fault) but only brake bumpers and camera, so I had to buy another one. That felt terrible, very expensive.I am still trying to re-engineer what happened during the fly away. At this point, I only have the flight path from my iphone. Device seems beyond repair, but may be DJI has some secret tricks.
Some key lessons learned though:
a) DJI disables multiple flight modes following firmware updates as was pointed out above (not sure how they can be so stupid to erase the previous setting given the quality of the firmware), but according to my flight plan, I could not enter in ATTI mode although I tried. MAKE SURE TO CHECK THIS AFTER EACH UPDATE OF FIRMWARE.
b) The Inspire accelerated to 17.1 m/s horizontal speed during its fly-away which is 40 mph. Given the weight of the drone, this represents a substantial risk for hurting a physical person or damaging property (Ironically I was actually relieved that the drone crashed in a solid house rather than something else).
c) The range before crash in case of a fly-away is substantial which raises the question about the safety of flying in open spaces within agglomerations (at least from my personal point of view).
d) The most scary part for me is that there is still no complete explanation by DJI of what really happens (IMU and compass calibration seem to be one, but I also found post http://www.phantompilots.com/threads/anatomy-of-a-dji-flyaway.42997/ that indicates more serious issues).
I will keep you posted on DJI feedback following the fly-away report that I filed.

With point a) are you confirming that that happened to you, so switch to ATTI is still safe? I agree, very stupid move from dji to reset settings, maybe they have a reason for that?
Having experience with DJI and their flight controllers (especially naza in the past) I rarely fly in GPS mode. Too many things are communicating with each other (GPS, barometer, gyro, compass, software) (ironically the app actually tells you to switch to GPS mode when you switch to atti mode) but as you said, GPS mode is just not 100% secure. Neither is flying solely in atti mode but it takes the risk down a factor in my pov.
it will remain altitude within a few feet give or take.If I take off with gps and then switch from GPS to atti mode, I know the inspire will drift with the wind freely, but will it maintain altitude? Is the craft able to hold altitude without input? What about updrafts?
He hasn’t been on here since July of 2015.Hi French, did you get any conclusion from the DJI investigation in the end?
