Sonex and Waiex B-Models have been enlarged by making the forward fuselage sides parallel, rather than tapering towards the nose, and the cockpits feature improved creature comforts. Specifically:

There is more width and comfort at the shoulders, hips, knees and feet.

The seat back has been moved aft, and new seat geometry accommodates taller individuals.

Staggered seating is available and the central, shared ‘Y-Stick’ offers dual controls with easier cockpit entry and roomier seating.

Electric Flaps reduce cockpit clutter and dual throttles are standard.

The enlarged B-Model instrument panel offers plenty of space for dual-screen avionics installations, including MGL iEFIS Explorer 8.5in displays. The new B-Model fuel tank holds 20 US gallons – a four-gallon increase over the original Sonex and Waiex.

Sonex Aircraft is expanding engine options with the Sonex and Waiex B-Models, offering AeroVee/AeroVee Turbo and Jabiru/CAMit 3300 engines, while adding engine mount options for UL Power 350i, 350is, and Rotax 912-series engines. The new universal cowl has been designed to fit all four options.

B-Model kits will ship with more standard features, and will require less build time. Assembled Wing Spars and Machined Angle Components are now standard. Upgrades and accessories such as the AeroBrake Hydraulic Brakes, dual AeroConversions Throttle Quadrants, and AeroConversions Trim System are now included. Build time improvements include more laser-cut, formed and machined parts, machined canopy bows for easier installation with a better fit, an easy-fitting horizontal-split cowl, and engine mounts that bolt quickly and accurately to the airframe.

B-Models will completely replace the original Sonex and Waiex in the Sonex Aircraft product lineup. Kits for the original aircraft will only be available for a limited time, however sub-kits will still be available to those needing to complete existing projects and legacy service parts will still be produced, according to demand. B-Models will only be available in kit form, however, the original model Sonex plans will still be available to scratch builders.
