Hi all ,has anyone worked out the best speed to fly in say calm conditions to get the most out of your battery. I usually go flat out in normal mode but wondered if anyone had worked out anything better

It should be right about 27mph, for the MA2, which is the max speed in N mode. It's been that way on all the DJI drones in P mode that max out at around 31mph. Tripod mode is too slow. Sport is too fast. Normal or Program at max speed is most efficient.From my usage it seems like flying around 20mph get's you the most miles per battery.
It's not hard to test actually. Just start flying at full speed at tripod mode (about 10mph) and look at how much battery time it calculates you have. Then switch it to 15mph but in normal and see it decrease, but not by too much. Try 16mph, 18mph, 20mph....where I found the sweet spot. Go to 22mph, 25mph, etc and you'll see the minutes drop significantly...at least they did for me.
That's a good idea I will try this and make a note of which seems best overallFrom my usage it seems like flying around 20mph get's you the most miles per battery.

While that is an interesting method, it depends entirely upon the remaining battery algorithm, rather than actual tested flight times to battery exhaustion from long distance flyers at different speeds on the different aircraft. The default RTH speed is always too slow, and you would assume it should be the most efficient, too, but it isn't. Try 27mph. It is likely far more efficient, for distance covered, than 20mph.From my usage it seems like flying around 20mph get's you the most miles per battery.

I agree with you...the default RTH speed is horribly inefficient. The drone is smart enough and should figure out the best speed to get back...but it doesn't do that. If you use the default RTH speed, you get home with less battery than if you speed it up.While that is an interesting method, it depends entirely upon the remaining battery algorithm, rather than actual tested flight times to battery exhaustion from long distance flyers at different speeds on the different aircraft.

What is your source for the max distance figure?
Isn't max time = 0kph?
If we're talking about time in the air, no. Hovering uses more energy than forward flight.Isn't max time = 0kph?
I don't have a specific source. When I got my MA2 about three months ago, the best speed for max distance interested me and I read up on it and watched max distance videos. Even came across some aeronautical engineers discussing it with formulae, although I don't recall where that was. The number was 36 kph. Interestingly with the current firmware and software, RTH is set by DJI at 36 kph.What is your source for the max distance figure?
In flight the drone generates turbulent air with a downward vector. The drone must then use more power to generate lift. By constantly moving, the drone will stay in stable air.If we're talking about time in the air, no. Hovering uses more energy than forward flight.
The 36kph/22.5mph is at least getting closer to the likely max distance speed of 27mph. What distance was covered at 22.5mph vs. 27mph, which is the max Normal speed? The RTH speed is almost never the max distance speed, although it always should be! RTH speed has always been around 22mph, yet the max distance speed on all Phantoms and the Mavic 2 series has always been the maximum speed in P mode, or roughly 31-34mph.
