Lancair Evolution to test Lycoming FADEC

The Lancair kitplane known, as Evolution, a blazingly fast form of transportation, first flew last year with a turbine engine, but now itıs flown with a piston engine.
The piston-powered Evolution flew for the first time in June and will become the demonstration platform for Lycomingıs iE2 series of muscle piston engines once it completes 10 hours of flight. It needs 10 hours not because itıs a new airplane, but because it needs to complete an aerodynamic profile before the iE2 can be mounted on the airframe. The engine is run by a computer, and these tests are telling the computer exactly how the airplane performs. Data is transmitted from the Lancair electronically for Lycoming engineers to view.
The first 10 hours will be done with the present Lycoming O-540 engine. The iE2 engine, capable of generating continuous power of 350 hp or 400 hp during takeoff and climb, is already waiting at the Lancair plant in Redmond, Ore. Lancair will install it and test fly it a total of 40 hours, a requirement for an aircraft that is experimental and powered by an experimental engine.
