Interesting facts about the Sonex Xenos-B
✈ Sonex Aircraft produces the Xenos-B as a two-seat kit aircraft in Oshkosh Wisconsin, with buyer outcomes heavily influenced by build quality and documentation.
✈ The Xenos line first flew on 19 July 2003, then Sonex introduced the Xenos-B in early 2017 with deliveries beginning the same year.
✈ Buyers choose the Xenos-B for dual-purpose flying, it can motor-soar with the engine off like a self-launch sailplane, or cruise as a powered sport aircraft.
✈ The B-Model widened the forward fuselage and revised seating geometry to add shoulder, hip, knee and foot room, it also expanded panel space for modern avionics layouts.
✈ Utility wingtips are removable for storage, owners can swap to shorter aerobatic wingtips for solo aerobatic category operation when configured and operated within limits.
✈ The airframe uses 6061-T6 aluminium construction, a practical advantage for owners who want corrosion resistant metal structure and straightforward field repairs.
✈ Sonex lists AeroVee 80 hp and Jabiru 3300 120 hp as common engine paths, the higher power option typically improves cruise speed and takeoff performance.
✈ The published glide ratio is 24:1, that gives powered-aircraft buyers a very different engine-out profile than short-wing sport designs.
Model Variants for buyers to consider when purchasing a Sonex Xenos-B
Sonex markets the Xenos family in two main versions, the original Xenos and the updated Xenos-B. The Xenos-B keeps the same motorglider concept but adds the B-Model cockpit and fuselage improvements that increase space, improve entry and expand instrument panel area. Sonex also increased fuel capacity on the B-Model which can matter for cross-country motor-soaring missions. When comparing listings, buyers should confirm whether a given aircraft is an original Xenos or a true Xenos-B, then match that version to their cockpit comfort goals, avionics plan and mission profile.

Find Finance for buying a Sonex Xenos-B
Need financing to purchase your Sonex Xenos-B Aircraft? Some lenders treat motorgliders and experimental aircraft differently than factory-built airplanes, so prepare a clear equipment list, build documentation and recent condition inspection details. Engine choice, avionics capability and the quality of the build record can influence terms and required down payment. Ask finance providers how they value kit-built aircraft and whether they require a specialist appraisal.
