So, okay let's it launched at 98 percent, and the only thing I did was turn off recording half way through the flight. Should I turn off OA Too? I have to tell you that today the wind was 3mph.
It looks like you tried very hard to lose your Phantom.
NEVER run the battery down that low - aim to be back on the ground before 20%
The time you are cutting it close is the day you can count on complications that slow you down so aim to always have a reserve.
Yes, you should have turned OA off if you want to go for distance.
You will get about 50% more speed with OA disabled.
You dawdled on the outbound flight with the speed all over the place and never going above 20 mph.
Traveling so slowly, the Phantom is using a lot of it's energy just to hold it up in the air.
The less time you fight gravity the more power you have to make distance.
RTH is a slow driver. You can drive 50% faster (with OA off) than RTH on auto.
Either cancel RTH and drive yourself or just leave it in RTH and push the right stick forward.
You came home at 273 feet.
If you are running low on battery, start your descent while returning rather than get home and then descend.
You got to 512 feet from home at 17:29 ... but then flew away to 2165 feet when the battery was at 7% and kept it in the air for another three minutes !!??
Don't do any more adventurous flying until you understand your Phantom a lot better.
