I'm new to litchi, (its still cold here to do long range mission) but i did 1.2km (total 2.4km)
my signal became bad at 600m , mission still go ok.
You need to choose a speed fast enough for the battery range ,
(my record without litchi was 1.7 km but i used sport mode to be able to come back...
please check the manual ,for the correct number
but i have a split level house and in Atti mode my spark
can not even go up to the ceilling
maximum 5 or 6 meter high Atti (15 feets)
Ok I found the solution,
I made a "reset to default" with the Dji assistant
(With the spark connected to the computer)
Now I have access to the sport mode !
This video look , like the video from the phone dji cache , and you also have your sound. It s not the real video from the spark. My video from the cache also lag , but from the soark sd card its perfect
Hi,
I can confirm , I have the same problem here. Same message on the screen .
I tried everything listed here.
I tried firmware refresh with the Dji assistant.
For now i dont really need the sport mode , but I hope to find the solution
Someday
