I did not find that topic with the search function, so here it goes:
I have flown waypoint missions with my DJI Mini (where flight time was always less than calculated time by the app) and now I want to fly one with my new DJI MA2. When I plan the mission with Litchi the app calculates for a 13.3 km roundtrip 27 minutes of flight time even if I set the cruising speed at 39.9 km/h (which is within N-mode capabilities). This is strange since mathematically flying 13.3 km with 39.9 km/h should take exactely 20 minutes! Why does Litchi then show a total flight time of 27 minutes for that waypoint mission?
20 minutes is very much doable with a full battery - 27 minutes might not be!
I have looked at some Youtube MA2 review videos and they confirm a max. total flight distance (not to be confused with max. range!) in excess of 15 km (DJI gives 18.3 km if I remember correctly).
So why the miscalculation of the flight time by the app and shouldn´t 13.3 km be within the capabilities of the drone? Has oneone already flown such a long waypoint mission with the MA2 and how did it go?
Thanks for some input!
