I was just out flying my typhoon h for the first time and while trying different things taking it slow. I had the unit about 5 ft off the ground with landing gear up. As I have read that some have landed with gear up I tried to lower drone but would not get closer to the ground than about 4 ft. I tried this in both flight modes and OA turned off but would not go any lower until I lowered the landing gear. I'm probably not the first to try this but have not seen anything about this on line.
