In the 1990s I tried my hand at developing an airplane. While that business venture didn’t make me a millionaire, it provided a valuable lesson about what it takes to stay in the light-sport airplane business. Later, I realized the project needed someone who understood building techniques better than I did. That man was Dave Ekstrom and he ultimately took over my design, the Cumulus, a motorglider. He calls his business Ultralight Soaring Aviation LLC .
In the world of soaring, a motorglider is an expensive flying machine, making it not so different than high-end LSA that cost $130,000 or more. But Ekstrom comes from the world of homebuilts and he knew he could produce a kit for a lot less if buyers were willing to pull a few rivets (about 300 total hours are needed).
One of the 21 Cumulus builders is Andre Girard of Ottawa, Canada, who kindly provided Dave with the photos you see (five Cumulus kits are now airborne).

Cumulus
Authorship Note: Although most pilot reports on ByDanJohnson are…well, by Dan Johnson, this one is not. Our great friend, Dave Higdon, created this flight review and we appreciate his willingness to let us portray it.
The article represents the Cumulus originally made by the first US Aviation, whereas today, the kit is being supplied by Ultralight Soaring Aviation LLC. [Nov. 2008]
Sailplanes, hang gliders and motorgliders suffer in “demonstration mode.” They can’t do what rivets the attention of the crowds: roaring takeoff runs that transition into steep best-angle climbs to pattern altitude before crossing the runway’s departure end.

New Cumulus Ultralight Motorglider
After a six-year wait the New Cumulus Ultralight Motorglider took to the air thanks to Ultralight Soaring Aviation owner Dave Ekstrom. The original Cumulus required some redesign work that Ekstrom and team accomplished and tested. Now, orders are building and shipments have started. Previous kit owners are getting changed materials that should allow them to get airborne and new owners are starting work on kits. Email Dave at: ekstrom@midwest.net
LSA Seaplanes — Sophisticated New Entries or Established, Proven, Affordable Aircraft?
UPDATE 11/28/21 — Vickers Aircraft sent fresh images and additional comments. See ••• below. —DJ
Excitement is in the air, even as the season wraps up activity here in the USA. Remember, while winter approaches for Americans, summer is coming to New Zealand.
That might explain an information deficit of late from LSA seaplane developer, Vickers Aircraft. People have been asking questions and reports have become infrequent. Uh, oh…!
Fortunately, the quiet period appears to have a good explanation.
Received November 24th, 2021 — “Hi Dan. Sorry (for a delayed response),” wrote Paul Vickers. “We are pushing very hard for a 10 December first flight. We are structurally testing the wing today.”
Often called a “strongback,” Paul refers to the I-beam steel testing jig seen in the nearby photo. “This was custom designed and manufactured by our Wave team,” he added proudly.
••• “Wave is not just another LSA,” clarified Paul in follow-up email.
Ion Aircraft Takes Off — Twin-Boom Tail Tandem, Light-Sport Aircraft or Experimental
A few years back at EAA AirVenture Oshkosh, I discovered a good-looking design but I did not see it each year. When I talked to developer Steve Martin, the project appeared interesting but it was not complete (at that time). The next year, I’d look for Ion Aircraft and might not find them.
Such is the nature of developing a small aircraft. Most aircraft buyers have little idea about the million and one things that must come together to create a design.
Once the aircraft has proven itself, the challenge starts anew to put a completed model into production. Usually financing becomes an obstacle to clear. I’ve faced this scenario myself — with a motorglider called Cumulus back in the 1990s — so I can confirm this is no easy task.
Nonetheless, I was pleased to receive a notice that Ion found a buyer for the project, a venture capital company at that.
Let’s Get High… Really High, OK? Exploring the “Upper Atmosphere” in a Pipistrel Motorglider
Probably like a lot of you, I enjoy different kinds of flying but if asked to state one favorite, it’s an easy question to answer.
I’m a great enthusiast of soaring flight. Over decades of sampling a large number of aircraft of every description, I’m still drawn to a machine, which lacking any kind of powerplant, relies on the performance of the design and the skill of the pilot to stay aloft. I remain fascinated with locating rising columns of heated air. Circle well enough into one of these invisible thermals and you may be rewarded with an invigorating sensation of lift, of riding the swirling airmass thousands of feet into the air …silently. It’s mesmerizing to observe the ground fall away as you are propelled higher and higher.
You may never have felt such thing and you may be hesitant about launching into the air in an aircraft that will allow only one approach and landing per flight; no exceptions.
DeLand Showcase 2017 Records Growth — Customers Flew & Bought — Vendors Smiled
The second year of the DeLand Showcase is over. Most folks I asked judged it a success. Year #2 year of this three-day event again logged weather that could not have been better. Sunny blue skies dappled with puffy Cumulus clouds, modest winds, and temperatures in the 80s (high 20s C° for our metric readers). DeLand is two for two!
What more could you ask? Well, that depends.
Customer traffic “was up every day over the same day last year,” observed show director Jana Filip. That is certainly trending the right direction. Was it enough growth to satisfy a key component of these shows, the vendors? That depends on whom you ask.
One prominent company told me they did not know if they’d be back next year, but few will be surprised to see them return anyway. After spending money on the exhibit space and the logistics of moving aircraft, preparing for the show, and housing staff on-site, vendors seem ever to yearn for more “foot traffic.” While acknowledging the yearning, most sales pros know that the question that truly counts is… Did enough customers show enough interest that you took orders or at least obtain qualified leads?
Midwest LSA Expo 2014 Highlights
The sixth annual Midwest LSA Expo just concluded. These LSA-only events offer a more intimate setting where you can speak at length with an aircraft or other product representative. They don’t offer the dense traffic of the big shows but the valued trade off is that nearly everyone who shows is interested. People came from as far as California and I witnessed many demo flights. The Mt. Vernon airport is as good as it gets for this purpose with easy access to big broad runways and plenty of open airspace. Lead by energetic Chris Collins, a team of volunteers made it work again. When the event isn’t swallowing all their time these folks have a little fun. Don’t worry about the nearby picture; TSA and Homeland Security can calm down. This was a planned promotional venture on the side of a great new restaurant called Rare, a chop house.
Beetle Power in a Jaunty Jodel D9
“It is a truth universally acknowledged that a pilot not in possession of a good fortune will be in want of a VW-powered aircraft.” Well, I’m not entirely sure Jane Austen would’ve put it quite like that but one thing is irrefutable: If you want to fly an affordable aeroplane then it may well have a Beetle engine! And, here’s a very interesting factoid: the most produced aero-engine ever is probably Lycoming’s O-360, with around 250,000 made. However, Volkswagen made more than 21 million Beetle engines!
An interesting facet about lightweight taildraggers such as the D9 is that they have to be ‘flown’ all the time, even on the ground. Consequently even while taxiing I’m very aware of the wind, because even with differential braking turning out of wind can be a bit tricky. Of course, such simple machines have very simple checks, and while running through my generic SEP checks (which take the form of an unwritten ‘flow check’ around the cockpit), I often get the feeling (and particularly if I’ve flown something a bit more complex the day before) that I’ve forgotten something.
Finding Answers in the Air — Lightening Your Mood
After my post about ups and downs with government and recreational aviation, it’s wise to keep perspective on the sheer joy that flying can deliver. Here’s Brit’ Dave Unwin’s take…
Why fly? I was thinking this just the other day while wading through three piles of unpleasant-looking paperwork. One pile contained reminders regarding renewal of my medical, BFR and BGA BI ratings, another had info on my VP-1’s Permit renewal and insurance while the third, and largest, held news which I planned to refer to while writing ny monthly magazine column called “Push to Talk.” The news was all pretty grim — airfields closing and fuel prices rising, EASA, airspace grabs, the outrageous proposals for the Olympics, Mode S, ad nauseum. Bored (and slightly depressed) I did the only sensible thing — I went flying.
It was a beautiful evening and my demeanor was improving exponentially as I approached the airstrip.
