Development
Former SZD sailplane engineer Adam Kurbiel designed the predecessor of 3X55, the EOL-VLA, to conform to European JAR-VLA rules. That plane was modified through the years to meet Canadian Advanced Ultralight and US Light Sport Aircraft rules. The 3X47 version is specifically for the European market to meet those standards.
The designation 3X55 means “3Xtrim Aircraft - 550 kg gross weight” while the 3X47 refers to its 470 kg gross weight.
The European versions feature extensive structural use of carbon fibre to achieve lightness, while the 3X55 is predominantly of fibreglass construction. Otherwise the two aircraft are similar in appearance and performance.
The 3X55 first flew in 1996 and by the summer of 2006 about 60 aircraft of both types had been produced by 2006.

Famous quotes containing the word development:
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
—Lawrence Kutner (20th century)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
