About the Waiex Aircraft WAIEX

The Waiex is a single-seat, all-metal sport aircraft designed by Sonex Aircraft of Oshkosh, Wisconsin, and offered as a kit for amateur builders. Introduced in the early 2000s as a derivative of the two-seat Sonex, the Waiex features a distinctive Y-tail configuration and was engineered to meet Light Sport Aircraft regulations while delivering spirited performance on modest power. Built primarily from aluminum using simple hand tools and solid rivets, the design emphasizes low cost, ease of construction, and aerobatic capability, making it popular among first-time builders and budget-conscious sport pilots.

Powered typically by converted Volkswagen automotive engines, AeroVee powerplants, or small Rotax and Jabiru units producing 80-120 horsepower, the Waiex cruises around 150 knots and climbs briskly despite its light weight. The aircraft's empty weight of roughly 580 pounds and maximum gross of 1,320 pounds place it squarely in the LSA category, yet its +6/-3g aerobatic envelope and roll rate exceed many certified trainers. The Y-tail reduces parts count and weight compared to conventional empennage designs, though it requires careful rigging during construction.

The Waiex has found a niche among recreational pilots seeking an affordable path to aircraft ownership and the satisfaction of building their own machine. Kit prices start well below typical factory-built LSA costs, and the estimated 600-800 build hours make completion realistic for hobbyists working evenings and weekends. While the single seat limits its utility for training or travel with passengers, the type's low operating costs and engaging handling have sustained a loyal following in the experimental aircraft community.
