Just bought an open box P3A, have ~15 days to return it. I noticed that the back rotors had a couple of nics (warning sign #1) and that there is a little scuff on the back of the phantom. (warning sign #2) I decided before trying to power up and go for a flight I should see if there are leftover flight logs on the device...I see about a months worth of flights. (About 10-12 total) I could use some help discerning if there was a problem with the drone...can anyone assist? What files are needed? DAT, CSV, Config/log text files?
