Sometimes you’re in the right place at the right time. Well, OK, I’m biased but I think pretty much any time at Wallaby Ranch — the iconic hang gliding facility south of Disney Orlando — is a good time. When it also happens to be “Demo Days,” Wallaby is a jumping place! Demo Days is a longstanding activity where the California manufacturer, Wills Wing, brings its newest hang gliders by the truckload so that any qualified pilots can fly them for purchase evaluation. Lots of other folks show up because it’s fun and exciting but also because organizers hold the event right before Sun ‘n Fun starts.
Wallaby customers compose the perfect crowd for introducing a lightweight trike that can be flown for soaring fun. Airborne Australia is the down under manufacturer of both hang gliders and a successful line of trikes; they own SLSA status for their XT-912 and XT-912 Outback.

Sun ‘n Fun 2023, Day 3 — Four-Stroke Power for Part 103 Ultralights, Available Now
If I hear one thing over and over it is this: “I want a four-stroke engine for my Part 103 ultralight. Are any available?”
For years the answer was, “Well, brand XYZ offered one but they disappeared from the market some years ago. One such winner I flew was the Bailey four-stroke out of England. However, a visit to their website recently was not very productive. Regretfully, other four-stroke powerplants are rare (although for slightly larger airplanes, Chip Erwin’s V-Twin will soon add to the choices).
Are you out of luck trying to obtain a Part 103 four-stroke? NOPE!
Aero 1000 Engine
Fine Swiss Engineeering
Air-Tech, Inc., is one of my favorite companies. While I love the people behind this Louisiana company, it isn’t their deep expertise, long experience, or even an endearing sense of humor that surrounds the Bornes — a father and son team to envy.
Aeroprakt and Aeros Continue Manufacturing Despite Senseless Destruction in Ukraine
The following story is one that moved me and might affect you similarly. I consider all recreational aviators anywhere in the world as fellow flying enthusiasts. Maybe you do, too? Whatever we fly, pilots share a love of aviation, regardless of what language we speak or what currency we spend.
I am flooded with admiration for those airplane producers in Ukraine who have courageously continued even as bombs fall and missiles fly. I have visited three Ukraine producers (some years ago) and I can only try to imagine what they are experiencing today.
In this article I want to shine a light on courageous efforts by regular Ukraine citizens to continue making aircraft that bring satisfaction to pilots in America and many other countries.
Aero Hang Gliders
and Nanotrikes
As you’ll hear in the first video below, I was told a compelling story about workers in Kyiv-based Aeros going to their factory pre-dawn, entering quietly, working with reduced lighting to be less conspicuous, and locking themselves in for the workday.
Four Stroke Power for Light-Sport Aircraft Aircraft? YES! …a Modern Rotax 582 Replacement
A common question from affordable aviation enthusiasts asks about four stroke engines, either for genuine Part 103 ultralights (available but somewhat more challenging) or for very light aircraft. Such inquiries are commonly for aircraft that have previously used a Rotax 582.
The last two-stroke offered by the big Austrian engine manufacturer — builder of the ubiquitous 9-series four-stroke engines — was the Rotax 582. Producing 65 horsepower and earning a good reliability rating over many years, the 582 has been a dependable powerplant for the lightest powered aircraft that are larger and heavier than genuine Part 103 ultralights.
2020 Sensation!
The one and only airshow in 2020 was the Midwest LSA Expo… about to start this week!
Two years ago, in preparation for the show, Chip Erwin lit up the blogosphere with his Merlin Lite entry (image below). Here’s more about that all-metal, weight-making Part 103 aircraft (our most-read article of 2020, which was then our strongest year ever).
Do You Love Ultralights but Prefer a Four Stroke Engine? Find It at Sun ‘n Fun!
A year ago at Sun ‘n Fun 2021, I reported on a Rotax 503 replacement built in Russia. This information was warmly received at the time because the 503 powerplant was much beloved by ultralight enthusiasts.
Little did we know last year that Putin would invade Ukraine and plunge both countries into disarray. The RMZ 500 engine seemed to promise a return to the popular engine. It will surely be months if not years before we see more of them.
Despite the former popularity of the Rotax 503 fifteen years ago, one of the most common questions asked of Part 103 producers today is, “Can you provide a four-stroke engine?”
It’s not an easy order to fill; two-strokes are potent sources of power at minimal weight, what’s called power-to-weight ratio. Any four-stroke engine is hard pressed to match the power-to-weight ratio of the best two-stroke engines.

Aviad’s Reimagined Zigolo Ultralight for 2022; Welcome to Mg21
Americans know Zigolo thanks to U.S. importer, Chip Erwin. He brought the genuine Part 103 ultralight to the USA but also to other countries where he found customers. Those who know Chip are aware he has many international connections.
Beside importing aircraft to the USA and helping customers build them, Chip experimented with electric propulsion for Zigolo.
In short, he did a lot for Italian producer Aviad but Chip is now focused on his Merlin PSA and Merlin Lite plus his Hybird V-Twin, 60 horsepower, four stroke engine. You’ll be hearing more about that as Sun ‘n Fun 2022 approaches.
Welcome to Zigolo Mg21
Check out earlier articles on Zigolo — here’s a full pilot report — but know this: While Mg21 shares the name Zigolo, nearly everything about the new model from Aviad developer Francesco Di Martino is different.
AirVenture Day 4: Generation 3 Ultralight Electrics — Where Electric Propulsion Works Today
A mid-week demonstration featured Europe’s Volocopter and America’s Opener BlackFly. The two (three actually, a pair of BlackFlys flew) demonstrated their eVTOL flying capability. They could hardly have been more different.
Billionaires are investing in, uh, what to call them? …drones, multicopters, eVTOLs, UASs, UAVs, Powered Lift aircraft, the list literally goes on and on. The lack of a widely accepted generic name is one of several indications these air taxis of tomorrow are still in a fairly distant tomorrow.
Two industry experts gave me their judgment after viewing the Volocopter and BlackFly demonstrations. Both agreed the Volocopter presented better, performing a true demonstration of its vertical launch then transitioning to forward flight, manuevering, and then doing a landing. Both also said the BlackFly was much less impressive. “They just kind of bobbed and floated around, not doing any maneuvering or making a transition to forward flight,” each agreed. Both wanted to like each aircraft but one clearly won in their minds.
AirVenture Day 0: Say Good-Bye to Rotax Two-Stroke Aircraft Engines
As AirVenture Oshkosh 2021 starts, we have arrived at a long-awaited beginning to the world’s biggest airshow.
AirVenture Oshkosh 2021 opens Monday July 26th and I am on-site to capture all the best news I can find for light aircraft.
Regretfully, my Canada-based YouTube partner, Videoman Dave, was denied entry by Homeland Security — his occupation was “deemed not essential” — so I’ll be flying solo to write daily articles and record video.
End of an Era?
As a company news release issued just before Oshkosh shows, we have also arrived at the end of an era. Rotax announced that the Austrian engine manufacturer will cease production of their last two-stroke powerplant, the twin-cylinder, 65-horsepower 582.
Indeed, as light aviation enthusiasts prepare for the coming Mosaic regulation that will dramatically alter the landscape, a clearer dividing line is revealing itself. Many light aircraft have embraced Rotax’s four stroke engines, overwhelmingly their 9-series models including carbureted 912 ULS, fuel-injected 912iS, turbocharged 914, and the newest 915iS.
Canada’s Chinook — Relocated to Texas and Upgraded; Now, “Made in the USA”
Then…
In the 1990s, a pair of Canadian aircraft dominated the light aviation market in America’s neighbor to the north. The two planes are known to many Americans: Beaver and Chinook.
Thanks to a rescue by second owner ASAP many years ago, both continued to be manufactured in Canada’s West.
Long-departed Birdman Enterprises did a fine job of originating the Chinook. When ASAP took over, Canadians and ultralight enthusiasts in many places celebrated ongoing support of this aircraft. Hundreds of Chinooks were built.
That is now rather distant history. Bringing Chinook not only into the present day but also into the USA is the Aeroplane Manufactory.
…and Now
For several years, ASAP sold the Chinook Plus 2, tagging the two-seater model with the “Plus” suffix after ASAP’s team improved and refined the aircraft following their acquisition.
In more modern times, after purchasing the Chinook design rights and inventory in 2013 (five semi loads’ worth!), Aeroplane Manufactory brought the north-of-the-border design way down south to the Houston, Texas area.
Welcome Hybird — New Four-Stroke Engine for Light Aircraft; Replaces HKS
A new engine was debuted at Midwest LSA Expo 2020 for light aircraft from Aeromarine-LSA. Paired as it is with a new engine-specific prop, this is a refreshing bit of news for ultralight enthusiasts and other single seat light aircraft lovers.
It’s called Hybird… and, no, I did not spell that incorrectly. As you’ll hear, the new powerplant has some possibility to be a form of hybrid (this time spelled as you expect) but it is different in that respect, too.
Since HKS decided to exit airplane engines — although our favorite datastician, Steve Beste reports he can still get parts for his HKS — the light aircraft industry has had an ear to the ground for a new four stroke replacement. It appears Chip Erwin has what many are seeking.
HyBIRD, not Hybrid
As those who know him realize, Chip does not just go out and find components for his airplanes and then adapt them to his designs.
