My mini 2 has recently started to show this when I fly , it first happened in my garden , I launched and sent it straight up to around 250 ft , I thought it may have been my metal shed causing interference , so I went to an open area  and flew   It was marginally better but at a height of 150ft and a distance of 350/400 yards the signal went from strong to moderately weak very quickly.
Does anyone have any suggestions please ? I love my mini 2 and want it to be at its best if possible.
