The UAS Company has ZZZ's permission to conduct UAS Operators out of ZZZ Airport. Our operations are always South of Runway XX/ XY and at or below 400 feet AGL to comply with Part  XX7 Regulations. We were conducting UAS Training out of ZZZ. We were in the air in cruise flight just south of Runway XX; staying clear of the departing and departure ends of all Runways. Mid-afternoon; [Aircraft Y] made a call mentioning he was coming into landing Runway XY. The individual did an extremely low pass down Runway XY near the aircrafts max speed. Everything was ok; until the individual decided to make an immediate left turn towards us which departed the runway heading and cut short of the end of the runway. At that point; we tried to direct the UAS the best we could to stay clear of the aircraft; but there was little to no time to do so. The individual did a 60 to 90 degree bank maneuver over our operations around 300 AGL to 500 AGL and came extremely close to our UAS which weighs around 15 lbs. Where we operate; there should be no manned aircraft in this area as it is not a part of the standard traffic pattern. The individual also knows that there is UAS operations in that area and that people are in the area.
UAV ground crew reported a NMAC with low flying aircraft that was not flying the airport traffic pattern.
