Most ultralight aircraft (officially: “ultralight vehicles”) are rather simple constructions. They must be to stay within the tight constraints of a 254-pound maximum empty weight.* That’s not a negative comment about them. Actually, it’s the opposite. To build a flying airplane that weighs less than the engine alone on a Light-Sport Aircraft, a designer has to be unusually clever. All aircraft are constrained in weight by the laws of physics. Ultralights are further constrained by regulation. A key way to keep an aircraft light is to keep it simple. Indeed most 103 ultralights are quite basic. However, as years passed some engineers have found intriguing solutions. I recently wrote about the composite Swan. Why not one using extensive carbon fiber? Carbon Corsair German developer Jörg Hollmann took a different approach, one that consumed a few years of effort. He wanted an aircraft that resembled the famous World War II F4U Corsair fighter.

In our original, longer video (below) you hear the sound of Corsair's engine with its distinctive low rumble. Some call it a "bark," others have said "growl."https://youtu.be/k5EF-RU8qMs
