Sonex Celebrates 25 Years with 19th Homecoming Open House

Tom Helm participated in the Sonex mass-taxi with his Oshkosh-based Onex.

Sonex LLC held its 19th open house on Sunday, July 23rd at their multi-hangar campus on the east side of Oshkosh’s Wittman Regional Airport. The annual event invites owners to display their aircraft among the Sonex hangars and provides an opportunity for Sonex enthusiasts to gather, explore the customer and factory aircraft on hand, meet the Sonex staff and fellow enthusiasts and tour the factory.

The JSX-2T prototype was on hand with its sleeker profile.

Sonex’s JSX-2T 2-place jet prototype was on display. Since its roll-out at last year’s open house it has been refitted with a much-lowered turtledeck and other system changes influenced by the prototyping process. It will remain in the Sonex hangar and will not be displayed in the Sonex AirVenture booth.

The High Wing prototype has yet to take shape in physical form though design and structural analysis continues. Mark Schaible, Sonex Owner and President, said “We’re really excited about the High Wing and are disappointed we were unable to exhibit it this year. We continue to make progress on the engineering side of the project but have to focus on navigating on-going supply-chain issues so we can service our existing customers. That takes precedence over new-product development.” Mark recommends that anyone interested in the High Wing subscribe to the High Wing mailing list.

Since AirVenture the 2022 the JSX-2T’s turtledeck was lowered significantly while preserving ample headroom for most pilots.

The event ended with a traditional mass-taxi of factory and customer aircraft to the homebuilt display area. Customer aircraft came from near and far. Tom Helm had his Oshkosh-based Onex on display and Noel Wade represented the upper west coast with his fresh-out-of Phase One AeroVee Turbo-powered Sonex.

If you missed the open house, you can sign up for a Sonex factory tour by visiting the Sonex booth (booth 602, on the corner of Wittman Road and Galatin Ave. in the homebuilt display area) or online.
