Sonex Aircraft LLC

Sonex Aircraft is one of aviation's best-known brands offering exciting performance, easy building, prices to match the budgets of most pilots, and you will do business with some fine people. Taking years of success to new heights, Sonex debuted the "B" models with numerous upgrades.

Price isn't everything. Most pilots know this. Yet every pilot, no matter how wealthy, keeps a focus on cost. A complete Sonex airframe kits is priced at $23,000. Even a quick-build B-Model kit sells for $30,900. That's less than average price for a new car these days. OK, so it's modestly priced. What do you get for the money?

Why are the B-models a move forward in the Sonex universe? They have more... room and comfort (Bs are wider and the seat is further aft); panel space (more room for big screens); fuel (now 20 gallons usable, up from 16); engine choices (a new Universal Cowl fits many popular engine options including AeroVee or turbo, Jabiru 3300, UL Power 350i, and Rotax 9-series) and Sonex provides engine mounts for all of those engine options; and, standard features (too many to list but, for example, fully assembled wing spars and more laser-cut, formed and machined parts to reduce fabrication time). On the other hand, B-models have... less build time.

One thing does not change. Sonex B models have the same great flight characteristics the brand has long properly boasted. Specs remain strong: empty weight 620 lbs; range 687 miles; cruise speed at Sea Level 130 mph (with 80-hp AeroVee) or 135 mph (with 120-hp Jabiru 3300); cruise Speed at 8,000 ft 150 mph (AeroVee) or 170 mph (Jabiru). As you can see, Sonex Bs do very well measured speed per dollar, too.

Put it all together with the AeroVee engine and Sonex said you can get airborne for $36,000, barely over the average price of new car but you'll fly twice as fast as the car drives and you'll have have ten times the fun. Add more money and get a SubSonex jet for even more airborne joy. In fact, Sonex has a line of models to satisfy most pilot interests:

  • Sonex-B and Waiex-B (discussed above)
  • Onex: Single-place folding-wing sport aircraft with a base completion cost of $28,699
  • Xenos: 2-place motorglider
  • SubSonex Personal Jet
  • AeroConversions: AeroVee Engines, AeroInjector carbs, AeroBrake hydraulic brakes, Throttle Quadrants, Trim Systems and more!

  Sonex -- AeroVee engine and airframe models
Sonex is one the world's most successful kit aircraft producers and they do it all. Sonex makes several interesting airframes and we'll have a look at them. Yet first we'll have CEO Jeremy Monnett show us around their AeroVee engine. They sell kits, and the engine is also a kit, not that it takes too much time to assemble. Hear all Jeremy's advice about powerplants and airframes from the Oshkosh, Wisconsin company that does it all and very well.
  $4.95 Homebuilts Under $40,000
"Budget Builds (Low Cost Homebuilts)" by Dan Johnson. Published in Kitplanes Magazine, June, 2005.
Pilot Report begins: Yes! You can build and fly a "real" airplane for the cost of a new SUV. Contrary to popular opinion, airplanes don't have to be outrageously expensive-at least not all of them. The Sport Pilot/Light-Sport Aircraft initiative is one program that promises to lower the cost of ready-to-fly aircraft. But many of these Special LSAs and Experimental LSAs will be priced well more than $40,000 and can run upwards of $85,000. One way to get airborne for less than $40K is to choose an ultralight, powered parachute

"Sonex Aircraft's Y-tailed Waiex" by Dan Johnson. Published in Kitplanes Magazine, April, 2005.
Pilot Report begins: Pedal to the Metal The Y-Tail Waiex combines unusual style with refreshing speed. The airlines may be suffering and Light-Sport Aircraft (LSA) has yet to coalesce into a coherent industry segment, but Sonex Ltd. is having a fine run of business. During my visit on a beautiful fall day in Oshkosh, Sonex said it was ready to break ground on a new hangar, the third building of what has become the Sonex campus on Wittman Field. At press time, it was nearly complete. Sonex is clearly ready for LSA, but
