    Hi
    I was out fly at sea today. I'm guessing the wind was probably about 15 -17 mph behind the p3a on the way out. I was out to about 1.5 miles. I did some flying around ships for a while. My p3a initiated RTH at 39% battery and got home with 23% in the tank flying into the wind. It did the same on all 3 batteries. My RTH is set at 25% in the settings.

    So, my question is does Litchi dynamically adjust the RTH battery setting based on distance and battery used to get there?

    Thanks
    Phil

    Yes, it calculates distance from home, altitude, average battery drain and it "decides" the point of return to home engage for battery remaining time.
    It was killing my P4 few days ago because I didn't know about this function (was activated in DJI Go: Smart RTH) and I was on a boat.
    After 3 NM and battery at 45% it suddenly started to fly back to home.
    Using sticks I was able only to stop it but, when I released sticks, it flied back.
    I was a bit scaried so I didn't notice that RTH was deactivable but, running with boat, I've been able to get back my P4.
