The Bottom Line: What Will My B-Model Cost?
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.
What is the B-Model? It’s what you’ve been asking for! More of everything you want in a sport aircraft:
|Sonex, Waiex and Xenos B-Models are enlarged via straightening of the forward fuselage sides, and feature improved creature comforts:
|The enlarged B-Model instrument panel offers plenty of space for today’s popular dual-screen avionics installations (MGL iEFIS Explorer 8.5” displays shown here) with room to spare.|
|The new B-Model fuel tank holds 20 US gallons – a 4-gallon increase over the original Xenos with a range increase of approximately 100 miles!|
|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 UL260 and 350 series, Rotax 912 series engines, and the Zaero Electric Propulsion Package.

The Xenos motorglider has been developed over a period of years by Sonex, LLC and the progress of Xenos development, including Wing Load Test Documentation, has been preserved in this archive.
The B-Models first began development in the Sonex Aircraft Hornets' Nest R&D Center in the Fall of 2015 and the B-Model Sonex and Waiex aircraft were announced in February 2016 with the B-Model Xenos being announced in January, 2017.

Sonex Aircraft's Waiex, Xenos and SubSonex aircraft models all share a very special feature: the Y-Tail! The Y-Tail is our unique version of the V-tail that many pilots are familiar with. What makes it a Y-Tail? The rudder! Y-Tails feature not-only a V-tail set of mixed rudder and elevator controls, but also a small rudder at the base of the tail, changing the shape of the V-tail to resemble the letter "Y." Y-Tails not-only make Waiex, Xenos and SubSonex aircraft look cool, but they also offer superior handling vs. conventional V-tails, offer a simple way to drive tailwheel steering, and gives the exhaust of the SubSonex turbojet engine a place to go. The Y-Tail's rudder gives the configuration enhanced rudder authority and stability vs. a conventional V-tail -- you need a rear-view mirror to tell whether you're flying a Sonex or a Waiex!
So what makes a Y-Tail work? Kitplanes editor, Xenos and SubSonex builder Paul Dye recently posted an explanation and videos of the Y-Tail in-action to his Kitplanes blog -- Check it Out!
Why a Y-Tail? Why Not?
