Many of us who enjoy soaring flight love the Pipistrel Sinus as it offers some wonderful gliding capability. Even the prop can “feather” to reduce drag. It works marvelously and can exceed 50 miles per gallon. U.S. representative Rand Vollmer shows us around the Sinus but then took us outside to see the “Flex” capability. Basically this refers to a variable wing span with extensions that remove in a matter of minutes. You’ll want to watch the whole video to see this feature set.
