Hi guys I try to fly near river. I just take him up fly over barrier  after went down and he lost conection with remote controler.... He was  so close and I had full battery but I canot do enything...  River was  bottom... After around minute he connect back with remote   I was so scarry because if battery will be empty he will fly back but  on the same level is barrier and he will crash, on top of me was  trees...  I was so lucky....

And now i realize that was strange because if he lose connection he  suppouse come back to home point. I set this up after couple secound but  that was almost minute and nothing...

Somebody can explain me what I done wrong ?

Just to let u know there was trees but top on me.... between me and dron was only barrier similar to this from events seriosly nothing was blocking signal... thats so strange

Seems like it went under the river at point c for its altitude is -5.9

Brother I was starting from embankment. That will be always higher than river but 100% he wasnt under river first thing was ice but so tiny to go there. Secound thing all time I had wisual contact he was so close
