    Has anyone figured out if there is a maximum "altitude" below take off for the Phantom 3 series? Is there a set limit like the 1640' above takeoff?

    I'm assuming there isn't since, generally, flying below takeoff would be a flight into a deep canyon or a crash. I'm curious because of the desire to fly in places with really dramatic changes in topography...

    There is no minimum altitude set in the firmware.

    Gringorio, no answer to your question but, my son- in law and I love flying on the mountain and are always looking for fellow phantom pilots!

    Not sure of a limit, but dropped into the Milk River, Alberta coulees last weekend. Vertical drop was just over -700 ft.

    Are you confirming this for the latest firmware?

    I haven't tested it, if that is what you mean, but there has never been a minimum. That would not even make any sense.

    I recall hearing about a -200m altitude limit. I haven't had anywhere to test this though. Although the -700ft is more than that, so perhaps there's no limit to negative altitude.

    At some point it may be possible to exceed the max pressure measurement range of the barometer but even then it would just remain at that value.
    There's just no reason to put a flight limit on a negative altitude.
