I want to be absolutely sure that the firmware and settings are saved after I did some test flights. I flew it for the last time: 1) ran the 2 batteries down to where the phantom led were blinking red, meaning batteries were 10% or less. 2) removed the batteries and will store for 1.5 weeks 3) gonna remove propellers, etc and box it up for the trip. So... when I get to Colorado and I take it out of the box, I just pop the propellers on, do Compass calibration, then I can fly? no need to check the settings, firmware updates, etc??? running the battery and leaving it disconnected for a week or two will not lose the calibrated settings? This will be the first real flights, and I just been practicing for 2 weeks learning about GPS mode, ATTI, HL and CL, all good so far.
