Aerobatic pilot Sean D. Tucker’s signature red Oracle Challenger III biplane weighs in at only 1200 lbs but has a souped up 400 hp Lycoming engine! The high power-to-weight ratio makes his biplane one of the most powerful aerobatic piston aircraft on the air show circuit. The fuselage structure of the Oracle Challenger III flown by Sean D. Tucker is made of aluminum tubing where instead of connectors, each tube is drilled and the next tube inserted and welded, creating a networked series of voids that is then pressurized with nitrogen gas- this is then connected to a pressure gauge in the cockpit- should a crack in the structure develop, the gas pressure drops and Sean D. Tucker is instantly alerted of a problem. With a roll rate of 400 degrees per second and a top speed of 300 mph, such a system lets him monitor the integrity of the structure even in the most punishing of aerobatic maneuvers. #Avgeek #aviation #aircraft #planeporn #KAFW #AFW #AllianceAirport #FWAAS2018 #AllianceAirShow2018 #airport #planespotting #Oracle #TeamOracle #OracleChallengerIII #SeanDTucker #instagramaviation #aviationlovers #aviationphotography #Avgeekery #instaaviation #aviationlovers #aviationphotography #flight #AvgeekSchoolofKnowledge (at Fort Worth Alliance Airport) https://www.instagram.com/p/BpqW6wQFkai/?utm_source=ig_tumblr_share&igshid=fw5c60jjabvm
