Xenos Motorglider

B-Model Features Have Made it to the Xenos!

Sonex Aircraft is extremely pleased to announce the new Xenos B-Model! The Xenos-B is available to order now, and kit shipments will begin in March, 2017.

The Xenos-B combines all of the great enhancements of the Sonex and Waiex B-Models with the outstanding motorglider performance and value of the Xenos:

More Cockpit &
Panel Space

Room to Share! Sonex and Waiex B-Models are enlarged via straightening of the forward fuselage sides, and feature improved creature comforts:

  • More width and comfort at the shoulders, hips, knees and feet.
  • Seat back is moved aft, and new seating geometry accommodates taller individuals. Staggered seating is available via upholstery seat back cushions.
  • Center “Y-Stick” offers dual controls with easier cockpit entry and roomier seating.

More Panel Space: The enlarged B-Model instrument panel offers plenty of space for today’s popular dual-screen avionics installations (including the MGL iEFIS Explorer 8.5” displays) with room to spare.


More Engine Options

A new Universal Cowl is designed to fit many popular engine options. Builders can experience the same great firewall-forward support for AeroVee/AeroVee Turbo and Jabiru engines, and in addition, B-Model engine mounts are available for UL Power and Rotax 912-series engines.

More Fuel

The new B-Model fuel tank holds 20 US gallons – a 4-gallon increase over the original Xenos!

More Standard Features and Less Build Time! Xenos B-Model kits come with more of what you need to finish your aircraft in the shortest time possible:

  • Machined Angle Components Included*
  • AeroBrake Hydraulic Brakes Included
  • Dual Throttle Quadrants Included
  • AeroConversions Trim System Included
  • ABS Molded Cockpit Side Panels, Cable and Pushrod Fairings Included
  • Precision-molded cowling is installed quickly and easily
  • Engine mount bolts quickly and accurately to the airframe
  • More laser-cut, formed and machined parts to reduce fabrication time and ease construction
  • Machined Canopy Bows for easier canopy installation with a perfect fit
  • Plus all the great features of existing kits: See What’s Included!

*Some Xenos angle parts are fabricated by builder, Assembled Wing Spars available at additional cost.

The Same Great Xenos Flight Characteristics: The best part of a Sonex Aircraft is the way it flies, and the B-Model Xenos will be no-exception!

  • Lightening the aircraft in key areas without sacrificing structural integrity gives the B-Model a very similar weight despite it’s larger size.
  • Performance specifications are equal. Takeoff, climb, cruise, stall, landing: the specifications are the same between B-Models and the original generation aircraft.
  • More engine options with 100 hp or more offers more options for enhanced performance with your B-Model.

About the Xenos: The XENOS follows in the Monnett tradition of bringing the cost of motor gliding to a highly affordable level. Using the same cost-effective and easy-to-build construction techniques and materials of the Sonex and Waiex, the Xenos offers another Reality Check for the soaring world. The Xenos comes standard with utility wing tips that can be easily removed to fit inside a 40 foot hangar, and can be quickly interchanged with optional aerobatic wingtips.

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 Xenos can be flown as a powered aircraft, a self-launched glider that soars with the engine off, or it can motor-soar over great distances with incredible fuel economy.

Xenos Development Archive: First released in 2003, the long-awaited Xenos motorglider was developed over a period of years by Sonex Aircraft, LLC and the progress of Xenos development, including Wing Load Test Documentation, has been preserved in this archive.

The Next Generation of Xenos: B-Models have completely replaced the original Xenos in the Sonex Aircraft product lineup.

  • Original model Xenos Sub-Kits will still be available to those needing to complete their existing projects.
  • All original Xenos aircraft will continue to receive full support, including legacy parts availability, if registered with Sonex Aircraft. As demand for legacy parts decreases, lead times may increase.
