Litchi, why flying speed are changing

[rattanat]

Make waypoint mission where all way points are height 60m, speed 0.9m/s(3.2kmh) and distance between all waypoints ~6m.

Why does the flying speed of M2 change during mission so dramatically? Can't understand the logic behind these changes. Also flying speed is too high most of the time. Have already try tweak all possible in litchi, l.ike "online elevation, speed, different amaount of curve, etc

I know it's not a drone error. I see the same change of speed when running that mission on Google earth. Also have an export *.csv file of the mission and there seems to be nothing weird.

My mission: Mission Hub - Litchi

I reply myself

figured out that if distance between waypoints are short like 6m the heading of drone obviously affects too. I mean camera have to travel longer distance if yaw change 50degrees instead of 25degrees. This obviously is not big issue when distance between waypoints are longer, but this case it makes the difference.

My new problem is how to adjust correctly when planning missions like this :\
