Xenos-B: The New Motorglider Reality Check
The Bottom Line: What Will My B-Model Cost? |
|
About the Aircraft
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.
About the B‑Models
What is the B-Model? It’s what you’ve been asking for! More of everything you want in a sport aircraft:
Room to Share!
Sonex, Waiex and Xenos B-Models are enlarged via straightening of the forward fuselage sides, and feature improved creature comforts:
|
 |
Glass it Up!
| 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. |
 |
Stretch Your Legs!
| 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! |
 |
Horses for Courses...
| 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.

Best Part of a Sonex: The Way it Flies!
The best part of a Sonex Aircraft is the way it flies, and the B-Model generation of aircraft is no-exception!
|

The Next Generation
B-Models have completely replaced the original Sonex, Waiex & Xenos in the Sonex Aircraft product lineup.
- Original model Sonex, Waiex and Xenos Sub-Kits will still be available to those needing to complete their existing projects.
- All original Sonex, Waiex and 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.
- Original Sonex plans will still be available for scratch building.

B-Model News & Development

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. See the B-Model News & Development Archive for all the developments along the way and any recent B-Model news! |

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?
