Man scalped by remote-controlled helicopter Roman Pirozek was killed in an accident while flying a remote control helicopter. A teenager has died after being struck in the head by a remote-controlled helicopter he was flying in a city park in the US. Roman Pirozek, 19, suffered the fatal head injury at Calvert Vaux Park in Brooklyn on Thursday afternoon, police said. Witnesses told police the helicopter Mr Pirozek was flying crashed into him, cutting off part of the top of his head and slashing his throat. He died at the scene. Mr Pirozek's father, who introduced his son to the hobby, is believed to have witnessed the tragedy. Mr Pirozek was vice-president of a local hobby club and appeared to have been an avid enthusiast of the remote-controlled miniature helicopters. Videos posted by Pirozek on YouTube and photos on his Facebook page show him working on the machines and flying them. One clip shows him performing tricks with his Trex 700 helicopter. The video culminates with him dropping the $1500 model from the sky and restarting the rotor when it was just centimetres from his head. A law-enforcement official told the Wall Street Journal that Mr Pirozak "was known to be aggressive in his flying and often executed tricks. He was executing a trick when he was struck. Pictures from the scene show the remote control near his covered body. Mr Pirozek's sister, Amy, told the Washington Post that her brother, who worked as a cargo handler for an airline, was ""the best person ever"." ""He had the biggest heart," she said. ""I think he was just doing it because it was his day off. He always protected me. He was a good brother. I'll never forget that. Calvert Vaux Park is designated by the city as a model aircraft field for enthusiasts. Fairfax Media, with wires Correction: An earlier version of this story incorrectly said the man was decapitated. He had part of his head removed, not his entire head.
