    OK, this just crossed my mind. You've allowed it to find all the sats (light is green), you do the compass dance again for the heck of it. You fly for 12+ minutes. It gets wobbly so you set it down.

    Now you swap out the battery to fly again. What happens to your compass/GPS info.? It would have to hold it in a CMOS type arrangment with a battery (or at least a trickle charge cap.)

    So, how long does this info stay in memory? What about the Phantom on the shelf with no battery attached? Do I have to do the compass dance again since its been powered down for weeks? Of course, it will pick up on the sats once you power it up and leave it alone.....but the compass?

    Maybe I was just over thinking this.... :twisted:

    It has to be stored in non volatile memory along with other data like Phantom/Naza mode, gimbal settings, S1 & S2 switch assignments etc

    Ah, NVRAM. Of course. I was preoccupied with something else and it seemd like a good question at the time...
