    Most battery efficient speed to cover a distance

    There are a number of variables I can't control, but it will be the best information we have. My biggest concern is the battery strength meter. Those numbers we see are based on some sort of dji algorithm, and who knows how linear it is in respect to energy available. It's probably the best...

    Most battery efficient speed to cover a distance

    OK, I gave it a try and the results were Inconclusive. I'll extend the distance to see what happens.

    Most battery efficient speed to cover a distance

    Tomk suggested that the frontal area effect was subordinate to the other effects, rather than to suggest that there was no effect. I don't suspect that any of us are making things up to support our agenda, but why not test these theories out? I propose we get our MM2s up in the air to 200' AGL...

    Most battery efficient speed to cover a distance

    According to my line of thought offered previously in this thread, the airspeed reduces the range at speeds beyond what the drone is capable of, so the faster the better within the speed range offered by the mini 2. This seems to align with your anecdotal information regarding range. Of course...

    Most battery efficient speed to cover a distance

    I am using two different references for relative speed in this discussion, and I think people are following along, but to be clear, the drag associated with high-speed travel is most pronounced at speeds in excess of what our mavics are traveling at. As such, the max speed for the mavic mini 2...

    Most battery efficient speed to cover a distance

    I agree that our positions are very close to one another. In my hypothesis I did not explain this but the underlying assumption is that as the forward speed increases the drag increases exponentially and that this indicates that fast speeds will reduce the overall range because of the energy...

    FAA "NO DRONES" Sign

    I agree that the mini 2 is not a toy, but FAA has described the category 1 drones as such.

    Most battery efficient speed to cover a distance

    From a vector analysis standpoint, the force to maintain the drone in level flight remains constant while the forward force vector will be related to the forward speed and drag. This shows that the range for a slow forward speed condition is limited by the energy expended to remain at altitude...

    Speed Test!

    35 mph in sport mode, 22 mph in cine or normal mode.

    Samsung A51 compatibility with the DJI fly app.

    I have the 4G A51 with my mini 2. I dont seem to have the follow me or cirvle functions, but i can otherwise use the drone just fine
