Checking in With Sonex’s Mark Schaible — Update on the High Wing and Will it Be a MOSAIC Design?

Gemini Sparkle

Key Takeaways:

  • Sonex Aircraft is actively developing its High Wing model, initially planned as an Experimental/Amateur-Built version with future consideration for E-LSA and S-LSA variants.
  • The High Wing is expected to deliver performance similar to Sonex's low-wing designs, with the first example featuring a taildragger configuration and a 130-hp ULPower engine.
  • The impending MOSAIC rule changes are critical, potentially allowing the High Wing to exceed the current 1320-pound LSA gross weight limit, thereby increasing its useful load and accommodating more builder additions.
  • Enthusiasts can expect to see a cabin mockup of the High Wing at AirVenture this year.

Light Sport enthusiasts who appreciate light, simple, inexpensive airplanes have been watching Sonex Aircraft develop the High Wing model for a couple of years now. It’ll first come out as an Experimental/Amateur-Built version but the company is very much open to considering an E-LSA and even, with some outside help, an S-LSA version. (Or whatever we’re going to call that once MOSAIC is real.)

Company owner Mark Schaible joins us to talk about the airplane’s gestation and expectations for performance and when it might fly. Hint: You’ll be able to see a cabin mockup at AirVenture this year at the least. In general, Sonex is hoping for performance similar to the low-wing Sonex designs and will be building the first example as a taildragger with a 130-hp ULPower engine. Schaible also discusses changes to the design now that MOSAIC is closer to reality. Expanded Sport Pilot rules could allow Sonex to give the High Wing a gross weight above the current 1320-pound maximum for LSA.

By expanding the max-weight envelope, Schaible hopes that the High Wing will have even better useful load and will be a better option for those owners and builders who inevitably want more stuff in the airplane that ultimately adds weight.
