Welcome back to the airplane equivalent of an old friend. As you can see at the bottom of this post, Videoman Dave and I did many video interviews with Chipper creator. James Weibe (view at bottom). Pilots seemed always to enjoy hearing about his latest development.
James came to aviation from the computer business, where the pace isn’t fast — it’s furious! Over the years Dave and I covered James and his output, we’d make a new video at every airshow, it seemed, as he had moved on from the last design to the next. That’s what they do in the world of computers but it made pilots’ heads spin.
It also probably slowed sales because, as with computers, why buy this airplane when the next one will be even better?
It Began with Kitfox Lite
James started out with the Kitfox Lite single place Part 103 ultralight vehicle. Current Kitfox owners did not plan to pursue the single seater that Kitfox founder Dan Denney had created years earlier.
Reorganization Approved: Van’s Emerges From Chapter 11
While the world of LSAs is diverse enough that the trials of Van’s Aircraft, which put itself into Chapter 11 bankruptcy protection late last year, aren’t quite the foundational matters they are among the homebuilt crowd, the fact that Van’s is represented with the popular RV-12 and companies that support it are also part of the LSA ecosystem suggests more than a little spillover. In the background, Van’s has been working hard to reset its business and emerge from Chapter 11. And on May 15 the company received good news in the form of an Oregon judge approving the company’s reorganization plan. While it seemed unlikely, there was always the possibility that the court would reject or modify the company’s proposal.
In the proposal, Van’s has agreed to repay unsecured creditors 55% of the money they’re owed over three years on top of an “immediate” repayment of $3350 for those in the unsecured creditor class.
Affordable Aeromarine Merlin LSA — What’s New?
When thinking of affordable aviation, it’s impossible not to talk about the Aeromarine Merlin LSA. This aircraft is a familiar design for many, as it made its premier in 2016. We’ve talked about it here several times. There have been some exciting changes and updates, a few of which we learned about last month at Sun ’n Fun.
The Aeromarine designed and built 60-hp V-twin liquid cooled four-cycle engine now comes as the standard powerplant. This is a modern engine with electronic ignition, electronic fuel injection and an electric starter. Merlin says this engine will cut fuel consumption at cruise to an average of 2.5 gph, approximately 50% less than the Rotax 582. The Rotax engine is still available as option for those builders that prefer.
The Aeromarine Merlin LSA will also feature as standard a deluxe MGL 8.5-inch EFIS with ADS-B In and Out (FIS-B) avionics panel, elevating your flying experience to the 21st century.
Summer’s Almost Here! State-of-the-Sector Report for LSA Seaplanes
One of the most active sectors in light aviation is LSA seaplanes. We’ve seen ups and downs, arrivals and departures of LSA seaplane producers. Admittedly, these flying machines are more complex than current-day LSA. For example, amphibs need retractable landing gear and substantial boat hulls able to take water loads.
LSA seaplanes constitute a highly fluid market yet we can see clues suggesting what might be ahead for some of the main brands. With summertime approaching, this State-of-the-Sector article attempts to keep up with the rapidly changing landscape (or waterscape).
We’ll first look at two high-end entries that have been in the news and conclude with present LSA seaplanes and their status in the market.
Vickers Wave
Writing for AVweb (part of Firecrown, which also owns Flying and ByDanJohnson.com plus several other publications), my fellow aviation journalist Russ Niles stated, “New Zealand-based Vickers Aircraft Company says it intends to make its first delivery of the Wave two-place amphibious aircraft to a U.S.
Not Bent — Whisper Sling Special Prop Breaks Cover
When we last wrote about the Whisper Sling, a version of the Sling LSA used in the Sling Pilot Training Academy in Torrance, California, one teeny tiny detail was left out of the story by request. It was the next piece of the puzzle, so to speak, to reduce the airplane’s sound signature and one of the places most airframers go to help reduce noise: the prop.
Not just any prop. This special “non-planar” three-blade prop designed by Craig Catto features an unusual bit of blade shape near the tips, all aimed at reducing noise while retaining or, even better, increasing efficiency. As tested on the Whisper Sling, the Catto prop showed strong thrust measurements (as seen in the video) and appears to have reduced noise, both on the ground and in the aircraft.
The key to reducing noise is to control the tip vortices.
Risen Group Plans Transatlantic Flight to OSH
You’ve heard of the Risen, Alberto Porto’s sleek, fast retractable that makes the most of its Rotax 912 power. With more than 180 mph on tap with the 912 iS, the Risen seems the perfect two-person traveling machine. It’s also one, like the Sparker, that would fit well into the new MOSAIC rules.
Well, Porto and Andrea Venturini are going to find out just how well it travels this summer. They’ve announced a “unique, record breaking flight across the Atlantic Ocean.” Only this Risen will be using the latest Rotax 916 iS, the turbocharged, 160-hp engine so many airframers are now fitting in place of the 915 iS.
For Porto and Venturini, “the plan is to cover 3200 kms or about 2000 statute miles across the Atlantic Ocean with a fuel consumption of just over 50 gallons of fuel at speeds up to 230 mph.
There’s a New Rotax Service Center In Town: LEAF Acquired By APS
Advanced Powerplant Solutions (APS) is a new company under the new ownership of Jeremy and Daniela Knoll, who you may know of AeroSport fame, that has purchased Leading Edge Air Foils, LLC (LEAF), which, among other things, was a Rotax independent service center for the central US. APS will carry on the Rotax-oriented business from LEAF from its base in Delavan, Wisconsin. They’re based at Lake Lawn Airport (C59), about 40 miles southwest of Milwaukee and 35 miles northeast of Rockford.
Joining the Knolls will be Brett Lawton, as their technical director. Jeremy and Daniela say that they are “dedicated to maintaining the legacy of LEAF while integrating innovative solutions and expanded service offerings. Customers can look forward to a comprehensive range of Rotax engines, parts, technical support, repair, and maintenance services. Our goal is to be the central hub for Rotax services in the USA, ensuring reliability, expertise, and the highest standards of customer service.”
While the company is getting spooled up, maintenance classes are on hold until Fall 2024.
Watch Three Guys Talk About MOSAIC!
With the MOSAIC program now through the comment phase and in the hands of the FAA, we thought it would be a good time to recap some of its key elements and use our considerable powers of observation and prognostication to provide a little context where needed. Join me, Dan Johnson and LAMA president Scott Severen for a wide-ranging talk on MOSAIC.
Dragonfly Is Back Home in Florida — Hang Glider Tug … Working Ranch “Tractor”
Dragonfly was born in Florida in the early 1990s. Back-of-the-napkin sketches started in the 1980s following the dynamic 1970s when hang gliding swooped into national awareness. What one designer did with Dragonfly would become one of the most celebrated developments in hang gliding.
Throughout the ’70s, hang glider designs accelerated smartly in glide performance and sink rate, stretching from slope-hugging 4:1 triangular-shaped wings to elegantly long and slender “bladewings” that could exceed a 20:1 glide yet remain foot-launchable and still be an aircraft you could carry on your shoulder (when folded down). Passionate enthusiasts thrilled to a 5X performance improvement in a decade or so.
In the beginning, most pilots launched off mountains to get enough height to catch thermals. Yet lots of America doesn’t have mountainous terrain. Florida had plenty of pilots eager to fly hang gliders but to find the best soaring, they had to load up their gliders and drive 10-12 hours to the hills of Tennessee where flight park operators like me catered to them with mountain launch sites.
MOSAIC Update & A Call For Questions
There’s little question we’ve covered MOSAIC extensively here on ByDanJohnson.com and have been looking ahead to a day when the proposal is a rule, sport pilots gain access to a whole raft of new aircraft, legacy LSAs have a chance to expand their operating envelopes and many of the companies planning to make new models that fit into the MOSAIC template actually come to market. Yeah, that’s a lot. And, yes, we’re all a little impatient for the FAA to make MOSAIC real.
Since the comment period closed in January, there’s been plenty of industry talk and one major airshow where MOSAIC was definitely a topic of conversation. With that in mind, Dan Johnson, Scott Severen (LAMA’s president) and I are meeting next week (virtually) to catch each other up on the program—video of this meeting will post here next week.
As we prepare for it, I’d like to invite you to submit questions you have and we’ll take them up during our chat.
