Generally, if it looks like a duck and sounds like a duck ... well, you know the rest. But the devil's in the details and as much as this engine looks (and presumably sounds) like a Lycoming 360, Superior Air Parts says its Vantage engine is "the newest FAA certified 180-horsepower piston engine." Last week, the FAA granted Superior a full production certificate for the engine, which was certified in April. Although in form it appears to be a Lycoming, Superior says there are significant improvements in design over the 50-year-old example and demand is strong for its "new" engine.
