Sonex Aircraft, LLC is very excited to announce its latest aircraft development project: Sonex and Waiex B-Models. What is the B-Model? Itís what youíve been asking for! More of everything you want in a sport aircraft:

  • More Room and Comfort
  • More Panel Space
  • More Fuel
  • More Engine Choices
  • More Standard Features
  • Less Build Time!
  • Same Great Flight Characteristics!

 

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.
  • Electric Flaps reduce cockpit clutter and Dual Throttles are standard.

 

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 Fuel: The new B-Model fuel tank holds 20 US gallons – a 4-gallon increase over the original Sonex and Waiex!

More Engine Choices: 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 will be available for UL Power and Rotax 912-series engines.

  More Engine Choices


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

  • Assembled Wing Spars Included
  • 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!

 

The Same Great Sonex Aircraft Flight Characteristics: The best part of a Sonex Aircraft is the way it flies, and the B-Model generation of Sonex and Waiex 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.


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

  • Original model Sonex and Waiex Sub-Kits will still be available to those needing to complete their existing projects.
  • All original Sonex and Waiex 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 Frequently Asked Questions:

  1. I previously bought a Sonex or Waiex Tail Kit, can it be used on a B-Model project? Yes! The tails are the same. Wings and fuselage are changed.
  2. I’m 6’4”, 220 lbs. Will I fit in the aircraft comfortably with a passenger?: As always, your fit in any light aircraft very-much depends on your individual body geometry, your standards of comfort, and the size of your passengers. The new aircraft is very comfortable with a lot more room than the original Sonex and Waiex, but we encourage everyone to try it on for size, either at our upcoming Workshops, at Sun ‘n Fun, or AirVenture.
  3. Is the aircraft Sport Pilot eligible?: Yes. B-Model aircraft powered by engines between 80-120 hp will definitely be Sport Pilot eligible, as are the original Sonex and Waiex designs. Aircraft with more powerful engines installed may not meet the Sport Pilot maximum speed limitations.
  4. How does it fly?: Just like the original Sonex and Waiex!
  5. Are the Sonex and Waiex B-Models be Aerobatic?: Yes, they are approved for the Aerobatic Category when flown at 950 lbs gross weight or under, exactly like the existing Sonex and Waiex.
  6. Can I still put Sport Acro Ailerons on the B-Model Aircraft? Yes, the flap and aileron kit parts will stay the same, and the Sport Acro control surface optional instructions will remain in the plans.
  7. Where can I see a B-Model in-person?: Come to our factory, or visit us at EAA AirVenture Oshkosh 2016!
  8. Can I scratch Build a B-Model?: The B-Model versions of the Sonex and Waiex are not available for scratch building. The original Sonex design is still available for scratch building, however, and we remain committed to serving the scratch building customer with that design.
  9. Can I get support to convert my Sonex or Waiex project into a B-Model? Yes! Conversion Kits are available!
  10. Can the B-Model fuel tank, or enlarged instrument panel be used in my original model Sonex or Waiex? No. The change in fuselage shape demands that these components be specially fitted for B-Model aircraft only. It is the changes to the B-Model fuselage that make these new components possible.
  11. Can I get a B-Model UL Power or Rotax motor mount for use on my original model Sonex or Waiex? No. B-Model motor mounts are wider, and attach to the fuselage differently. Other vendors may be able to help you engine mounts for Legacy Sonex and Waiex aircraft, or for your Xenos or Onex. UL Power dealer Kaolin Aviation Services can do custom UL Power mounts for homebuilt aircraft, for example.
  12. What kind of Firewall-Forward Support can I expect for UL Power or Rotax installation in my new B-Model Kit? Sonex Aircraft is providing engine mounts for these engines, and a cowling in-which these engines will fit. Sonex customers have successfully used these engines in original model Sonex and Waiex aircraft in the past, but the Sonex factory does not have a UL Power or Rotax installation its factory prototype fleet at this time. Beyond providing engine mount and cowling for B-Model kits, added installation support is not provided by Sonex Aircraft for these engines. There are, however, many support materials available for installation of AeroVee/AeroVee Turbo and Jabiru/CAMit 3300 engines in Sonex Aircraft.

 

B-Model Conversion Kit Considerations:

B-Model Conversion Kits are now available! Please Read the following important information:

  • No exchanges of legacy Sonex or Waiex parts are available.
  • Builders will have to get their projects to a defined "starting point" for conversion. That may mean either building-up to the point where changes begin to take place, or removing parts to get "back" to the starting point of conversion changes. See our B-Model Conversion Process Description document for more information.
  • Depending upon a project’s status and condition, builders may need to fabricate or purchase replacement legacy (A-Model) parts at additional expense that are not part of the conversion kit. This will be more likely if builders need to remove parts to return to the conversion’s defined "starting point."
  • No "partial conversions" will be supported — Sonex Aircraft can only offer support for construction as defined in the plans that are provided for conversion.
  • Wing conversion kits do not include new B-Model wing skins, as the conversion is most economically made by trimming existing wing skins. Builders may opt to purchase new B-Model wing skins at additional expense.
  • Builders must retain their original legacy plans set with their projects and legacy aircraft serial numbers will not be valid for building additional projects. Legacy aircraft that have been converted will receive a version of their original serial number that includes a conversion designator.
  • See our list of legacy Sonex and Waiex kit parts NOT used in B-Model Conversions (preliminary, subject to change without notice).
