Interesting facts about the Sonex-B
✈ Sonex-B is the B-Model evolution of the Sonex two seat, all metal, low wing homebuilt aircraft family, with kits produced by Sonex Aircraft in Oshkosh, Wisconsin.
✈ Sonex introduced the B-Model to give builders more interior space, it removes the forward fuselage taper and delivers a 40 inch wide cockpit across the full width.
✈ The B-Model adds endurance, it uses a 20 US gallon fuel tank, which increases range compared with the earlier legacy configuration.
✈ Many Sonex-B aircraft qualify for Sport Pilot style operations in the United States when built and equipped within the applicable limits, which can expand the buyer pool.
✈ Sonex-B commonly flies with engines in the 80 hp to 130 hp class, including AeroVee installations and Jabiru options, which changes cruise performance and useful load.
✈ Buyers often value the B-Model panel space, the larger firewall and instrument area can support modern avionics layouts that do not fit as easily in earlier builds.
✈ Sonex offers B-Model conversion kits for some legacy airframes, so a listing may be a factory B-Model kit or a converted aircraft, paperwork clarity matters.
✈ The design targets efficient cross country sport flying, owners often highlight strong speed per gallon when the aircraft is built light and rigged correctly.
Model Variants for buyers to consider when purchasing a Sonex-B
Buyers will see two main Sonex generations in listings, the earlier legacy Sonex and the Sonex-B B-Model. The Sonex-B keeps the same general two seat, low wing concept but reshapes the forward fuselage to create a full width 40 inch cockpit, a larger panel area and room for more engine choices. Sonex also supports B-Model conversion kits for some legacy aircraft, so the airframe history can differ even when the listing title says Sonex-B. Engine selections also create meaningful sub types in the market, AeroVee and AeroVee Turbo installations often prioritise lower engine cost and builder involvement while Jabiru powered aircraft often target higher cruise performance, these choices affect resale, maintenance planning and insurance requirements.
