Recently i made a trip to Sumatra, indonesia to visit family and to record a small home made doco about the pekanbaru death railway which was built during the war by pow's and locals. I had issues with my osmo at first but a clean up of the battery terminals got that going and it worked well from there, even in the hot humid jungle. I also used my dji phantom 3 std which worked awesome and in some cases i managed to push 1200m without signal loss most likely due to the lack of interference. Only my fear of losing it stopped me going further. I also used a small dashcam wich was ok for in the road stuff but thats about it.
