As an owner of a DJI mini se for the last 3 months in the Uk I thought the following point regarding transmission might be of interest to other users. I live in a small country town now almost surrounded by new housing developments, but as I normally fly no further out than 200 to 300 mtr radio contact is easily maintained. Being a CE dual band model set to automatic mode I had always assumed the drone would be flying on 2.4ghz frequency by default but on checking during a flight saw that it was on 5.8ghz. Tried to change in manual mode to 2.4ghz but although there were a few green channel bars as soon as one was selected that too turned to red. Although as I mentioned a new housing development as been built, most of the houses are not yet occupied so unlikely to be wifi interference from there preventing the use of 2.4ghz transmission. There is a mobile phone mast less than a hundred metres away so perhaps that is the problem. Anyone else had a similar experience?
