Hi...."Disable VPS, fly at least 20m above water"
OK but what does that do or how does it help over-water flights?
The questions are:
"Hi guys, I'm will sorry for my bad english but I'm a italian guy and my english is very poor ...

I live in Bellagio, near the lake of Como, and usually I fly near the Mountain. The days go on and now I want to Explore new area, here now rest only the lake ( to cross it I have about 3km), I have a lot of pain to cross the lake, because if I have fault of battery or engine ( motor), I have only to saw bye bye for my drone...the lake is deep 412mt.
Do you have experiens or many hour without problem due your drone? Now I have 90 hour of flight and I hope to fly more again but with the water is not possible take a prank.
Thanks a lot guys!
Ciao
