So took my mini 3 for a quick test run out in backyard, ( did my updates yesterday), i know airflow is key to keeping the drone cool, but just flew around for about 20 mins in normal mode and both the rc controller and drone seemed hotter than normal, controller was as hot as my android phone after a couple of packs in my mini 2 before switching to the smart controller which does not get hot. Had the screen brightness at 75%. Will have to test at flying field this weekend.
