Practical Utility Meets Builder Flexibility
Sonex Aircraft’s new Highwing is fast becoming a phenomenon among experimental aviation enthusiasts, blending advanced utility with aerobatic handling and builder-focused customization. The October 8 webinar, hosted by EAA and archived online, offers an in-depth look at the Highwing’s progress since its first flight on June 30 and its wildly successful public showcase at AirVenture 2025. Since AirVenture, the Sonex team has focused on integrating pilot feedback, optimizing kit production, and refining details for builders eager to start their projects.
Modular assembly meets modular kit pricing
The Highwing stands out for its modular assembly offerings and transparent pricing. Builders can choose a Complete Airframe Kit for $39,000 or step up to the Quick Build Kit for $55,000, saving considerable build time. For those who prefer to manage costs or time, Sonex’s sub-kit approach allows targeted purchases: $2,250 for the tail, $15,600 for the fuselage (with a Quick Build upgrade at $10,000), $15,000 for the wings, and $6,200 for gear and controls. Tri-gear options are available as standalone add-ons for $1,250, giving builders the choice to tailor their aircraft for bush strips or paved runways.
The Highwing’s powerplant compatibility, streamlined gear swaps, and large cabin access have caught the attention of both first-time builders and those graduating from other Sonex models. Designed for both STOL efficiency and spirited flying, the aircraft supports a robust 130-HP engine and is eligible for both tri-gear and taildragger configurations. The model’s approachable build experience and ergonomic cabin make it an attractive option for solo flyers or those carrying passengers and baggage over longer cross-country routes.
Sonex President Mark Schaible highlighted in the webinar that ongoing test programs are being shaped by builder feedback, and improvements are rolled out rapidly to support real-world needs. Builders investing in the Highwing not only benefit from technical updates but are welcomed into a vibrant online community—forums, builder groups, and factory support remain a cornerstone of the Sonex ethos.
We didn’t set out to build a bushplane. It’s meant to be aerobatic and fast, just like a Sonex. People compared it to a Wittman Tailwind, which I think is a compliment
Looking to the coming months, Sonex plans to ramp up kit deliveries, expand its support offerings, and continue to refine the build documentation thanks to input from its growing pilot network. As builders report progress and share experiences, the Highwing’s modular architecture and practical cost structure are transforming the expectations for utility kit aircraft. For pilots seeking a blend of adventure, true builder engagement, and value-driven utility, the Sonex Highwing is setting the pace for modern homebuilt aviation.
Randall, thanks for the coverage, but I think it’s hilarious that you make mention of the aircraft being for “bush strips” and STOL despite the huge block quote of me saying that the aircraft was not designed to be a bush plane. Could this have something to do with the fact that an AI detector says there’s a 98% probability that this was written by AI? Also interesting that you asked me for permission to use our images but didn’t ask me any questions about the aircraft or mention that you were running something about our most recent webinar. The “Easy Button” approach that KITPLANES has now applied to journalism has really degraded the quality of the coverage, but again, thanks for the effort I guess.
Amen.
Well, since The president of Sonex is here in the comments section of this article, I feel compelled to take this opportunity to ask. Mark, where do you recommend someone with no prior experience in mechanics learn the basics of kit plane building, like riveting? Is there a way to learn to build one of your planes without having to get some kind of formal aircraft technician certification training?
Having built one Sonex (A-model Sonex) and looking at the possibility of building a second (High Wing), I can can honestly say perseverance is the key to building an airplane. I built the first one with no experience in aircraft construction. I’m and Electrical Engineer by training, but never shied away from any home improvement tasks. Having good peer support is also great to have. That includes EAA, EAA Chapters, Facebook Groups, Sonex Forums, etc. Sonex used to do a Builder’s Workshop that introduces you to all the parts you’ll face building the airplane. Mark can expand on this, I am sure.
