I took my 12th flight today and noticed a strange sort of buzzing sound when I landed and the props stopped.
I used RTH to land as I've done for every landing to this point. When I noticed it at the first landing, I took her up again and landed one more time to see if it would do it again. Sure enough, same buzzing sound.
I don't know if this makes any difference, but the outside temperature was 32 degrees (F). Maybe a bit colder than my other flights, but that's the only difference relative to those other flights. I was also flying in a location that I've flown before.
Oh, and I haven't done the firmware upgrade (given some of the horror stories out there).
Any thought or suggestions?
