Sonex Announces Immediate Closure

Originally published at: Sonex Announces Immediate Closure

Owner Mark Schaible cites sales decline, lender pressure and cash-flow constraints in video message.

Terrible news for all those who have bought partial kits and also for suppliers, employees and Mark’s family.

I can’t help wondering if this was an example of the Osborne Effect, in which a company finds itself competing with its own future products. In other words, I’m wondering if too many customers who might have bought a Sonex kit were holding off because they were excited about the High Wing and/or the 2-seater jet.
The Osborne Effect is named after an early 1980s home computer company, which announced an upcoming new model before it was ready to sell it. Buyers stopped buying its existing product to wait for the new one, which ruined the company’s cash flows and resulted in its bankruptcy. It sounds awfully similar.

First dibs on the high wing prototype!!!

No, i think that it sunk because people today have the attention span of a cat. And if one cannot do anything without a telephone in their hand, it won’t get done.

Karroilot the data does nit agree with you New Kit Planes

The kit industry is growing at about 7.3 percent which is much faster than the economy as a whole.

A reading of the release plainly stated the firm had Been doing poorly with declining sales and a significant carrying debt. IF you cannot service debt you go out of business. VANS would up in a similar position due partly to supply shortages but largely due to some poor engineering decisions which resulted in a large increase in costs with no improvements in revenue. They survived as thier creditors were willing to carry the debt and forgive a lot of money.

It would be interesting to see what percentage of people buy those kits, as opposed to just how many kits get completed. And actually flown. Me personally, am a rental pilot. I don’t have the time, space, money, and wherewithal to go the kit plane route. I would probably be retired and or dead before it would come to fruition…

Sonex is dealing with normal business and does not understand the power of their resale customer base. Let me explain this with another company example. A well known successful Recumbent Bicycle Mfg called “Easy Racers” of Watsonville, CA adjacent to the Watsonville Airport made the best recumbent bikes to date. They were so good that their most popular model
“Tour Easy” has been ridden Coast to Coast across the USA more times
than any other Bicycle Brand and model! 100% true. The owner died and the business was sold to a guy who liked motor cycles more than bicycles.
He combined the two businesses. He redesigned the Tour Easy and Gold Rush and I bought both because they were better. He complained to me that
the Easy Racer used bike market was killing his new bike sales!! I told him “No your used bike sales give your loyal customers value and advertisement
when they sell their old bike to buy a new bike from you!”. No one who does not know Easy Racer is going to buy a $5K bike cold off the press. By supporting the used bike market you are giving loyal customers value in the resale to buy your new bike because they know and trust your business.
Your new bike is not twice the bike value of your older bikes! I have always
bought used before this sale. I bought a great bike for half of what a new one was. I took a chance on it and now like your bikes enough to buy new!

All 100% true! In the end he convinced himself the problem with new sales was the used bike market so he stopped supporting those customers!
He promptly went bankrupt and shutdown the best Easy Racer line of Recumbent bikes ever! No old customers or new customers would buy anything. So Sad…. My point in telling you this story is because SONEX is telling us the used sales are starving the new sales! Bullshit! Sales come and sales go and the real truth is the high wing took too long to develop!

How many $200k Jet customers are there? How many High Wing customers are there. Well I know for a fact that about half of all aircraft sold are high wing and half are low wing…. Let that sink in a bit.. If Sonex just put all hands on deck to complete the hight wing it would immediately double its sales !!!

This is yet another sad story of mis-management and once again mis-blame
of sales data and failure to recognize the value of any customer who flys or rides your products! Guys this is not hard! What do car dealers do with used cars? Yea, trade them in all day long and all they can get!!! In the case of the
bicycle dude, I told him to offer a trade in for every new bike that was a previous customer. Get that bike for a song and resell it for more profit.
Then the mfg could make a market in the used value of his bike brand.
Set a floor price to support your new price!! And support every customer
who rides your bikes, build loyalty and value. Make it profitable because
you set the prices. Do not blame your customers for your ignorance and greed! Maybe ignorance is too kind a word, “Stupid” might be more accurate.
For sure it was the right word for Easy Racer!

To be fair, it is near impossible to sell used homebuilt airplanes and avoid
extreme financial risk. However, you could pass everything to a licensed broker to buy from your trade-in fleet and be hands off of that risk. Sonex could manage a relationship by having the customer sell directly to the
broker/dealer and that money goes to the purchase of a new airplane kit!
The broker does not even have to pay Sonex on delivery, just on re-sale.
Any number of ways this can work.

I just wrote a business plan and case study for it. Someone should buy Sonex and light the fire over there before its to late. They need to up the brand and hang on to the value they have built into the industry by upgrading their products. Double down and take advantage of MOSAIC!!!

From the business situation which is the topic the purchase of the kit is what is important. Are you are NOW asserting with no information to back you up that there is NOW a reduction incompletion rates heretofore NOT seen in the data? While there is no single official database for every kit sold, industry data from

KITPLANESand major manufacturers show that completion rates have improved dramatically from a roughly 10% success rate decades ago to roughly 50% today for modern kits.

Key Historical Trends

  • The Early Era (1960s–1970s): Building often required “scratch-building” from plans, necessitating master-level skills in welding, woodworking, or composites. Completion rates were low, with some experts estimating only 1 in 10 kits or plans-built projects ever made it to the air.
  • The “Kit Revolution” (1980s–1990s): The introduction of high-quality kits, like the

Christen Eagle II

and early Van’s Aircraft RV series, began to simplify the process with better manuals and pre-fabricated parts.

  • The Modern Era (2000s–Present): Advances in computer-aided design (CAD) and CNC-matched-hole technology have reduced build times from thousands of hours to as few as 500–1,500 hours. These “quick-build” options have pushed completion rates for popular models toward the 50% mark.

Support Limited to letters/calls Online communities & factory workshops

Why Projects Stall

Despite improvements, roughly half of all kits still go unfinished. Common reasons cited by builders on forums like Van’s Air Force and EuroGA include:

  • Time & Life Changes: Projects often span 5–10 years, during which family or career demands can change.
  • Financial Constraints: The total cost of an aircraft can be three times the initial airframe kit price once engines and avionics are added.
  • Technical Fatigue: Losing momentum during complex stages, such as wiring or fiberglass finishing.
