I just took my Mavic on the beach for the first time. There was fog in the AM, but we took it for a flight, nonetheless. Always LOS. But when we finally landed, there was moisture on the arms. Wiped it off and ran the Mavic a while to ensure the inside was dry. So question is, any risks here with salt mist from the waves or moisture from fog? Would leaving the lens cover on help, or make a difference? Thanks.
