Key Takeaways:

The Sonex Highwing is actively under development, targeting a new market segment including pilots who prefer high-wing designs, older individuals seeking easier access, and those with disabilities, emphasizing aerobatic capabilities and higher cruise speeds over STOL performance.
Sonex plans to offer the aircraft as traditional, quick-build, ELSA, and SLSA kits, aiming to broaden its appeal to a wider audience, including the primary flight training market.
Preliminary specifications target Light Sport Aircraft (LSA) compliance with a 1,320 lbs max gross weight, 720 lbs empty weight, multiple engine options, 30 gallons of fuel, and features like a BRS ballistic recovery parachute system.
The prototype of the Sonex Highwing is scheduled to debut at EAA AirVenture 2023.
