One Week Wonder
February 3, 2022 –When volunteers gather at EAA AirVenture Oshkosh in 2022 to build an airplane in a week, that Sonex Waiex will feature a Rotax 912iS engine, bringing top engine technology to the One Week Wonder project. The One Week Wonder will start construction on Monday, July 25 — the opening day of AirVenture — with a goal to taxi the airplane during the final day’s air show on Sunday, July 31
The Rotax 912iS was also the choice for EAA’s One Week Wonder projects in 2014 and 2018. The fuel-injected engine provides durability and outstanding fuel economy for kit aircraft. “Rotax’s involvement in the One Week Wonder project will help our volunteers and those participating in the project at Oshkosh next summer create a superb aircraft and show how aircraft construction is within the abilities of most people,” said Charlie Becker, EAA’s homebuilt community manager. “Quality, reliability, and economy are attributes that we seek in this project, and the Rotax engine helps us get there.”
The installation of the Rotax 912iS will also be a first for Sonex factory-designed installations, as Sonex expands its level of support for Rotax 912-series engines installations in its airframes. “The inclusion of a Rotax engine in the One Week Wonder shows the flexibility available with the Sonex airframe designs and the additional possibilities for builders,” said Mark Schaible, owner of Sonex Aircraft. “We’re working with our suppliers and technicians to ensure that the first factory-designed Rotax installation is an excellent fit for the Waiex and other airframes, and is fully supported by us.”
Additional details of the 2022 One Week Wonder project will be announced as they are finalized. Thousands of AirVenture attendees participated in the previous builds at Oshkosh, with each of those airplanes continuing to fly today as excellent examples of amateur-built aircraft quality and workmanship.
