The Black Tiger was custom-created to become the ultimate modern art piece. The materials used by the artist RT include 3 authentic aircraft propeller blades with 3-bladed hub and cylinder. All parts are made of aluminum and have been highly polished and painted. The parts were manufactured by McCauley and modernized by Plane Pieces Inc. The propeller used to be part of a real flying airplane that had eventually been grounded. Each of the blades measures approximately 35" in length and 6" in width. The art piece has a total diameter of approximately 72". It weighs around 50 lbs. The art piece comes complete with gloss red cylinder, gloss red snap rings, steel bolts, gloss black hub, and set screws so the blades can be adjusted and held in a fixed-pitch position.
