Pawel a keen Drone enthusiast I bumped into, in an open industrial area, where he was practicing his skills with two types of drone. His skills from what I seen are beyond enthusiast, a pro drone operator. He does it as a hobby for now while he works in a good job he said. You can check out his skill via his Youtube page as called Airdrone Longford, link below, just click on image to go direct to page.
