Narrative:
Uav was being flown over parent's home and surrounding neighborhood within visual line of sight. At time of incident; uav was being flown at approximately 200 ft AGL. Upon hearing an approaching helicopter; uav was immediately commanded to descend and land as quickly as possible. While uav was descending; helicopter entered view of pilot on the ground and helicopter flew overhead of uav without altering flight path. Uav was never in the direct path of helicopter. It was originally assumed operation was conducted outside of class B due to distance to cle being greater than 5 statute miles. Upon review after the incident; operation was only 4.5 nautical miles from cle and within the class B.
