I've heard numbers around 45 km/h for best "milage" and used that for my litchi missions but then I thought that it would be nice to see if the theoretical values match with the real values....
In the litchi log you have current draw and battery voltage which gives you the power consumption in watts.
You also have speed and time and that gives you the distance.
By dividing the power consumption with the distance covered over one second you get watt*seconds/meter.
I did a mission in litchi with speeds from 10,15,20,25,30,40 km/h (no wind at all) and also used sport mode to get higher speed. I opened the litchi log in excel and calculated the numbers and it actually matched up really nice!
The best milage seems to be around 40-50 km/h so for long flights use sport mode.
But what happens when you add wind to the equation?
My gut feeling is that you should use sport mode and full speed against the wind and also fly low (just like the birds handle head winds).
Y-axis is (Watt x Second) / meter, X-axis is speed in km/h
