so this was a few weeks ago and i still think about it. was flying my Mavic Air 2 out over a reservoir near my house, maybe 400 meters out and probably 60 meters up, totally normal conditions, clear sky, very light wind. and then the RC just goes grey and i get the disconnected warning.

i had return to home set to hover which in retrospect was maybe not the smartest choice over open water but i panicked a bit and just waited. it felt like forever but i think it was maybe 20 seconds before the signal came back and i just immediately flew it back. no idea what caused it, there wasnt any obvious interference i could see. someone mentioned 2.4 vs 5.8ghz switching could cause a brief dropout but i dont really understand how that works technically.

drone was totally fine, footage actually looked great from that flight which is kind of funny. just shook me up a bit. anyone had similar dropouts over water specifically? i feel like water does something weird to signal

water absolutely messes with signal reflection, its a well known thing. the signal can bounce off the surface and cause multipath interference which confuses the OcuSync or whatever version is in the Air 2. your instinct to just wait was actually the right call in that situation. and yeah hovering over water with RTH set to hover is a bit sketchy, id change that to return to home altitude and make sure its set high enough to clear any obstacles on the way back if you're going over open water again.

glad it worked out though, those 20 seconds feel like 20 minutes when it happens

had almost the exact same thing happen over a bay last summer. mine came back after maybe 30 seconds and i was already mentally calculating how far i'd have to swim lol. changed my RTH settings the same day. water flying is just a different kind of stress honestly
