    Here's a problem to test your mathematical and engineering skills.

    How big would a Phantom have to be, to fly on Mars?
    (Imagine a ground station flight returning to an auto-recharge station. ;)

    The Mars atmosphere is about 7.5 millibars, compared to Earth being just over 1,000 millibars.
    Gravity on Mars is 38% that of Earth.
    Average temp -63C

    Doing a few calculations, I decided that an up-scaled Phantom would have to have a diameter of about 200cm or 80in, yet still weigh about 2kg on Earth, and without dirk's "passenger."

    Bonus question: Would DJI replace a fly-away on Mars?

    Biggest problem being the temperature and Dirk's passenger who has only grass skirt for protection.

    Edit: And unknown amount of contraband.

    hmmm.. reminds me of what they say about kilts (re what she's packing)...

    Would the thin atmosphere contribute to or cure VRS issues?
    And would the hula shake make VRS worse?

    Hula counteracts VRS.

    Put the large Phantom on an even bigger bouncy ball. Then descend and ascend over and over and over, with little power from the battery, assuming you develop a heated chamber for the battery. Then we need several GPS satellites orbiting Mars. I'm sure our next president will approve this mission...
