April 2017 logged 12 years of Light-Sport Aircraft. The FAA regulation creating the category was introduced in 2004 but it was at Sun ‘n Fun 2005 that the agency presented Evektor SportStar and the Flight Design CT the first and second Special Airworthiness certificates.
My friend and LAMA associate, Jan Fridrich, gave a presentation at Aero 2017 showing many graphs that examine this new airplane sector and how it has developed over the last decade. This article looks at a portion of his analysis.
In those dozen years, the market has developed interestingly.
In the first vigorous years of growth — filling pent-up demand for a two-seat aircraft pilots could fly without a medical — European light aircraft producers dominated the market (chart). Jan’s home country, the Czech Republic, was one of the most prolific, in the early days leading all other countries. Czech designs remain a key player but the field has shifted.

Google’s Larry Page Building an Ultralight? Yes!
Mainstream media outfits exploded with news of Google’s flying car. Although such news outlets rarely seem to notice recreational aviation other than when an accident occurs, the reports I read did a respectable job of covering flying car projects we already knew about (reported here and here earlier; some projects have advanced, some have dropped out, and others have arrived).
One glance at the images tells you this is no “flying car,” as no car is involved. More accurately, Kitty Hawk’s Flyer is an ultralight vehicle in the water thrill craft or all-terrain vehicle category … making it sort of one of “ours,” if I’m permitted to stretch the possessive.
Funded by Google founder, Larry Page — an uber rich tech personality — Kitty Hawk is not simply an exploratory project. They actually plan to sell this cool little rig. Flyer is an open-seated, 220-pound empty weight octocopter with seat (saddle?) for one person.
Vessel of South Korea and Flight Design Offer KLA-100
Recently, Vessel Co., Ltd., and Flight Design made a joint announcement after debuting their new KLA-100 low-wing, light aircraft at Aero Friedrichshafen 2017. Few expected this from the make of the very popular CT-series most recently including the CTLSi. Through 2016, this has been the most popular Special LSA in America.
The companies’ KLA-100 development program started quietly two years ago.
“The first flight was performed in Sumperk, Czech Republic in late March 2017 with test pilot Richard Ponizil at the controls. Since that time the plane has made seven more flights and met all expectations,” said Flight Design COO, Daniel Gunther.
KLA-100 is a brand new design destined to be certified as a Light Sport Aircraft for sale in countries that accept ASTM-compliant aircraft, with plans to meet the European EASA’s CS-LSA regulation. The companies think this will allow access to virtually every major aviation market in the world.
Remos Light-Sport Aircraft Has a New Owner: Stemme
On April 13, 2017, only briefly after the Aero Friedrichshafen show ended, LSA manufacturer Remos has a major announcement. “Remos has a New Owner,” exclaimed the German company on their website home page.
Stemme and Remos decided to work together more closely. “The only logical step was to merge both companies. Stemme AG ist the new owner of Remos AG. Remos now is a 100% subsidiary of Stemme,” said Stemme CEO Paul Masschelein. Stemme’s facility in Strausberg and the Remos facility in Pasewalk will continue to operate.
To reassure customers old and new, Masschelein added, “The Remos GX is a major part of our plans for the future.”
Both companies are referring to the move as a “merger.” This transaction follows a cooperation beginning in 2014 when Remos AG began producing structural composite parts for Stemme.
“The agreement has been unanimously approved by both companies’ supervisory boards,” they reported.
Swan Ultralight Goes Both Ways: Electric & Gas
In my views of Swan at previous Aero Friedrichshafen shows, the design caught my eye as it was (a) a single seater, (b) light enough to qualify as a Part 103 ultralight or its European equivalents, and (c) as it was an all-composite, nicely designed aircraft. Commonly, Part 103-capable designs are much more basic to remain within the tight limits. This statement also applies to the German 120-kilogram category or to Britain’s Single Seat DeRegulated (SSDR) description.
As Aero contributor and Powered Sport Flying publisher Roy Beisswenger and I frequently discuss, the most likely place for electric propulsion to work today is in ultralights. This is because in very light aircraft with more local flying missions, battery weights for a modest period of flying (30-60 minutes) is already achievable in the very lightest of powered aircraft. We have been discussing this with FAA for more than three years.
Here Comes FX1 Light Aircraft from Italy
In the late 1990s, the Italian JetFox 97 flew as an evolved ultralight. Resembling the FlightStar that sold around 1,000 units in all configurations, JetFox differed by enclosing the engine and cabin. Instead of a simple tail boom the European ultralight had an aft fuselage among other refinements. As Light-Sport erupted into the marketplace, JetFox appeared to slip away. However, good ideas can be recycled and revived. Such appears to be the case for FX1.
John Hunter has extensive experience with Drifter, AirCam, and several Aeroprakt models. Recently, he has been in Italy visiting Innovaviation to conduct the first test flights.
Created by JetFox designer, Alfredo Di Cesare, FX 1 is a modern aircraft cabin and fuselage structure made primarily of light weight carbon-graphite composite with wings and tail built from aluminum. Under the shapely skin is a cage of welded chromoly steel that provides robust occupant protection.
Alfredo wrote, “FX1 is a fourth-generation sport plane [that] evolved from successful European designs of the last three decades.” Using computer-aided design FX1 “has been carefully engineered to optimize all aspects of a proven configuration.”

Electric Propulsion Innovations at Aero 2017
Electric aircraft may still have minuscule market share but innovations could change that in the near future. As Aero correspondent, Roy Beisswenger wrote, “This is a rapidly changing technology with both motors and applications showing up all over Aero Friedrichshafen.” This year Aero management concentrated them in one of the big halls where small startups to the heavyweights were located. Thanks to Roy for several reports from Aero, of which this is one. —DJ
Many of the exhibited motors are for very light applications such as light-weight shift control trikes or gliders but motors are becoming more powerful. With an increase in power, new technical problems need to become overcome. For example, the larger the power capability of the motor, the more cooling is required for the motor. Smaller motors are mostly air-cooled, but some of the medium and larger motors require liquid cooling. This doesn’t mean that the motors have radiators, but liquid is built into the motor to help wick heat away from hot spots that are created when electricity is converted to mechanical power.
Searey Kit Aircraft Gets More Push… Simply!
Could Light-Sport Aircraft, light kit aircraft, and even ultralights benefit from in-flight adjustable propellers? After more testing and data collection answering that question should be easier.
Prominently displayed in front of the Rotax Aircraft Engines exhibit at Sun ‘n Fun — right at the main entrance to the large spring show — was a strikingly-painted Searey kit-built aircraft (photo). Why? The mission was to showcase how a Rotax-powered amphibian aircraft can get more push… without complexity.
Named Searey ATD, Advanced Technology Demonstrator, the collaborators include Progressive Aerodyne, producer of the Searey, Rotax Aircraft Engines, and MT Propeller, all coordinated by key developer, RS Aerotech of Nassau, Bahamas.
A joint news release said, “For the first time in the Light-Sport Aircraft category*, Searey ATD offers a single-lever operated constant speed propeller, which significantly improves performance and dramatically reduces power management complexity for the pilot.”
Searey ATD “will be used for long-time testing of new engines, propellers, and electronic systems.” To serve this goal, Searey ATD has been equipped with a state-of-the-art flight data acquisition and reporting system, which combines engine data with aircraft and navigation data.” Called a “first time” accomplishment, Searey ATD can “automatically transmit its engine and aircraft data via LTE networks worldwide.” The data “will be used by Rotax to perform engine health monitoring” similar to what airlines do globally.
25th Aero Friedrichshafen Enjoys Record Participation
The German aviation trade fair or show is Aero Friedrichshafen. This year the event at the very southern edge of Germany celebrated its 25th birthday. Over the years, Aero has emerged as the premiere aviation event in Europe, at least for airplanes that ordinary people can afford. Good friend and highly accomplished journalist, Marino Boric, submitted a lengthy report on the event, which we will break up into more bite-sized pieces. Here is Marino’s overview. —DJ
On Wednesday, April 5, the Global Show for General Aviation started for the 25th time. The 2017 edition opened with a record participation of 707 exhibitors from 39 countries, some 100 more than in 2016, presenting the best results in its history. Not only did more vendors attend this benchmark Aero, even the number of visitors numbers increased on first three days by six percent.
With Sun ‘n Fun also reporting record numbers, the health of lighter aviation appears strong and vibrant.
Sun ‘n Fun Set an All-Time Record, Announced at Volunteer Dinner
John “Lites” Leenhouts announced to a largest-ever gathering of volunteers that the event had set all-time records for attendance at the 2017. Clearly pumped by the positive results, Lites made his way around the small army expressing himself like the gracious professional he is.
How good was attendance? “They completely ran out of weekly armbands and had to resort to some 2016 armbands or daily ones,” said longtime reporter and co-star of Uncontrolled Airspace Dave Higdon, who has regularly attended Sun ‘n Fun since the early 1980s. We discussed the event and its evolution to become a major worldwide aviation show as Dave and I also celebrated 40 years since my hang gliding school taught him how to fly (we were mighty young in those days, I rush to add).
Ben Sclair, publisher of the airshow newspaper, “Sun ‘n Fun Today,” and General Aviation News backed up the assertion of very strong results for 2017 Sun ‘n Fun, saying that not only did his paper have a full slate of advertisers but he’d personally seen solid traffic everywhere he went tracking down stories for the daily to report.
