Figuring folks who discuss prop efficiency would also be interested in overall/range efficiency...
I'm flying a Pixhawk on a hexacopter (F550 frame).
But I am really just looking for a general answer as to the usually most efficient tilt angle for the average multi-rotor (as in milliamps used vs distance flown).
Specifically...I'd like to know my approximate max range when flying a mission...how far can I fly out and back and still land, with, say, 20% battery left? And at what tilt angle is that?
Is that maybe a 30-degree pitch forward? More? Less?
I'd like to program in a tilt angle or speed into my mission planning so as to be able to achieve max range and/or be able to spend the most time "on station".
Of course I realize wind will be a factor, but that is beside the point of this discussion.
Thanks...

Gererally speaking, for a multirotor, higher velocity will "always" give lower energy consumption while travelling a given distance.
How much it *can* pitch is not really related to speed. You may command 80degree pitch if you like, but it's not very likely you have the power to maintain altitude at that attitude.
if you are really interested in max pitch, just turn it up to a level where you can , in manual mode, still maintain altitude while giving max input - then you will find what's the max for your hexa - if you want it to be max whithout descending.
Andre,
So you are saying, essentially, that 100% throttle is the most efficient for max distance traveled per mah used?
In other wrods, find the max pitch angle where altitude can still be maintained at a given weight?
Thanks...
