Sonex Aircraft recently announced a new Xenos B-model aircraft kit, which combines the enhancements to the company’s Sonex and Waiex B-Models with the motorglider performance and value of the Xenos model.

In a written statement, Sonex Aircraft’s General Manager Mark Schaible said the company was thrilled to be bringing the improvements to the Xenos B-Model, adding that “This change has been requested by many prospective Xenos Motorglider customers and brings all of our two-place aircraft up to the same enhanced B-Model specification.

Enhancements to the Xenos B-Model

According to the company, though the B-Model is larger in size, it’s actually lighter due to modifications in key areas, all without sacrificing any structural integrity. In addition, the takeoff, climb, cruise, stall, and landing performance specs are the same between the original generation and B-Model Xenos aircraft. Here are some of the improvements the B-model provides:

  • A new Universal Cowl will allow for additional engine options, which offer enhanced performance. According to the company, in addition to “the same great firewall-forward support for AeroVee/AeroVee Turbo and Jabiru engines,” Xenos B-Model kits now have available engine mounts for “UL Power and Rotax 912-series engines.
  • New B-Model fuel tanks hold 20 gallons, an increase of 4 gallons over the original Xenos model.
  • The new Xenos B-Model kits come with a number of improvements aimed at aiding builders in completing their aircraft in the shortest possible time:
    • Machined Angle Components are included
    • AeroBrake Hydraulic Brakes are included
    • Dual Throttle Quadrants are included
    • AeroConversions Trim System is included
    • ABS Molded Cockpit Side Panels, Cable and Pushrod Fairings are included
    • The new precision molded cowling is able to be installed quickly and easily
    • The engine mount is able to be bolted to the airframe quickly and accurately
    • In order to reduce fabrication time and ease construction, there are more laser-cut, formed and machined parts.
    • Inclusion of Machined Canopy Bows for an easier canopy installation and perfect fit.
  • The B-Model comes standard with utility wing tips that can be easily removed in order to fit the aircraft inside a 40-foot hangar. They can also be quickly and easily interchanged with optional aerobatic wingtips.

According to Sonex, the Xenos can “either be flown as a Sport Pilot/LSA, or it can be flown by pilots that hold a glider rating with a self-launch glider endorsement.

The company says that Xenos B-Model kits are available for order now, with a base price fo $27,495 for the complete airframe kit. The company estimates that kit shipments will start in March 2017. For more information, and to order a B-Model kit, you can visit the Sonex website.
