Here is the link to the report
Your flight distance to home would have only been 6 km which should be easy.
I'd be doing quite well if I got $5 for every flyer that goes too high and pays no attention to the wind.
You flew at 670 feet where the wind is always going to be much higher than down on the ground.
At 4:20 you made an easy 14 metres/sec with obstacle avoidance enabled.
That tells me there was a good tailwind at that point.
Around 5:20 you took it up to 670 ft and kept powering away further downwind.
Now if you zip away with a raging tailwind, how do you think the return trip is going to go?
<<Hint>> You're going to have to turn around well before 50% if you want to get home
<<Hint>> You should get down out of that wind if you want to see the drone again
Around 7:27 at the turn, things slow down so you switch to (battery burning) Sport Mode.
You seem to have trouble steering straight and wiggle all over the sky while your battery goes from 50% to 40%.
You give up on Sport Mode at 8:20 and continue wandering, switching to RTH after a while at 9:38.
You've been making 1.8 metres/sec in P-GPS and the drone is still up 538 ft.
You bring the drone down to 260 ft and the speed picks up to 4-5 m/s
At 13:23, battery at 9% and 730 metres from home, the drone gives up and autolands before it runs empty and falls.
Any ideas of what did happen or maybe a setting or 2 that I can tweak or maybe this is a common issue that has a fix that I haven't heard about yet. thanks in advance everyone ..fingers crossed there is a fix!
Yes, it's a common issue.
What you have to tweak is your awareness of wind speed and direction and think what it will mean to the drone, especially the return trip.
