I heard again today from Jim Lee who’s still overseas helping prep the PhoEnix electric motorglider for July’s big, $1.65 million CAFE Green Flight Challenge (GFC) fuel-efficient flight competition in Santa Rosa, CA. *** Jim sent along photos of the electric nosecone with integrated feathering prop/spinner assembly. First test flights of the PhoEnix are planned in a couple weeks. *** BTW, the enhanced streamlining afforded by the much smaller e-motor boots the lovely creature’s performance from L/D 32:1 to 36:1 — a 12.5% increase! That’s great for soaring and also means less power required to sustain flight, the Big Picture for endurance at this stage of electric aviation. *** The GFC PhoEnix entry will be powered by a 44 kW motor and controller developed in house by Phoenix Air. *** Lipo (lithium polymer) batteries, popularized by the RC model industry for their light weight and high storage capacity, will hold the electric “gas”.

Virginia Festival of Flight Starts April 30
I have more to report from Aero 2011 in Europe, but let’s take a quick jaunt back across the Atlantic for an upcoming event of interest to LSA fans… The 14th Virginia Regional Festival of Flight runs April 30 and May 1, 2011 and it offers special opportunities for the Light-Sport crowd. *** Public Relations Chairman Dee Whittington, noted, “As usual we’ll have a dedicated [light aircraft] runway and parking area. Also, most of our manufacturers who will attend are from the Light-Sport community.” He continues with a bit of very important info both to vendors and those pilots wanting to carefully check out a LSA with a demonstration flight, “A good feature of our full-featured fly-in is the ability of vendors to do demo flights during the day instead of waiting until after 5:00 PM when the event shuts down.” Major airshows like AirVenture and Sun ‘n Fun have windows for free flying that restricts the number of demo flights aircraft sellers can provide (although Sun ‘n Fun offers Paradise City as an on-site alternative which can insure more such purchase evaluation flights).
PhoEnix: “E” as in Electric
Scoop time!
I’ve been having so much fun lately writing the electric flight article (now rescheduled to Aug. issue of Plane & Pilot) that it’s bringing electrifying news from the universe to my email inbox.
Jim Lee, that hard working, happy-flying distributor for the Phoenix motorglider I was gobsmacked with at Sebring, told me today about the PhoEnix all-electric version of the Rotax-powered motorglider that is selling like hotcakes here and abroad.
Here’s some of what he had to say: “Reporting from the Czech Republic where I am spending 2 weeks assisting in the production of our new electric PhoEnix. The weather has been great… soaring 5.5 hours in the last two days… I see that your blog has sort of turned into an electric blog lately, so that gave me the idea to report to you first on our electric project. Orders for the Rotax Phoenix are pouring in, so we had better stop flying and start working.”
Oh, for that challenge: to fly, or handle orders for your aircraft!
Getting a Charge
Well, Thomas, you’ve done it again: gotten me to blather on so long with your as-always thoughtful and knowledgeable comments that I exceeded the comment buffer so have to palaver on here in another post. *** Well, that’s why they call it a weBlog I guess: it’s a place to hang our thoughts out to dry. *** So what’s below is a response to your comment from yesterday’s post, with a couple more pix thrown in to thump the eye candy factor. *** I think we can’t overlook the market factor here. Just as car manufacturers know where the buyers are, it could be what we’re seeing with these projects aiming toward higher/faster/more payload electric are manufacturers figuring that they’re since they’re going to sell more of the expensive, travel-capable airplanes than sailplanes and motorgliders anyway, why concentrate time and resources on a transient, historically tiny share of the market? Leapfrog to the future, expect the tech to come along as needed.
Electric Flight: More Thoughts
Yesterday a reader commented on my electric flight post, specifically about the LZ FES, a pretty sexy add-on that just won the Lindbergh LEAP prize for best new electric propulsion system. He wondered whether electric flight for now required light weight motorgliders or whether heavier, 15M plus sailplanes/motorgliders would be workable for electric power. *** My answer began to get too lengthy to stick in comments so I’m posting it here, and thanks Thomas for your enthusiasm. *** I talked over this very subject this week with Randall Fishman, the award-winning electric flight pioneer. His take on where we’re at right now is in my Profiles in Vision column, coming in the July issue of P&P. *** Randall’s whole trip is to get people up in the air with electric power right now, and not for 150,000 clams either. To summarize his own one-man research and development plan, it’s all about lightweight motorgliders.
Aero: Lycoming Coming to More Light-Sport Aircraft
While the Continental O-200 engine — used in several Light-Sport Aircraft — attains Chinese ownership, Lycoming appears to be making a stronger push to enlist LSA manufacturers. *** One example at Aero 2011 was the upgraded Tecnam Eaglet, which airshow visitors could compare with either Rotax or Lycoming O-233 power. The appearance difference was significant and may test the market for preference for the European Rotax engine that powers 75% or so of all LSA versus the standard bearer Lycoming that has hauled generations of Americans through the skies. *** A major difference is the air-cooled Lycoming versus the liquid-cooled Rotax. Those big fins to cool the Lyc’ demand what one Tecnam rep’ called “power bulges.” The effect on the nose cowl surrounding the engine is dramatic and I’ll bet pilots like one or the other better… which is exactly the point. Tecnam will continue building both so you can — as Burger King puts it — “have it your way.” *** The company has also upgraded the interior of the Eaglet, launched at Sebring 2009, with a highly finished interior complete with new interior door treatments (photo).
LEAP Awards Electric Aviation Prizes
Eric Lindbergh, grandson of Charles A. Lindbergh, awarded the LEAP Prize to Pipistrel’s Ivo Boscarol at the just-finished Aero General Aviation convention in Friedrichshafen, Germany. *** The 3rd annual e-Flight gathering took place there also, and Lindbergh’s Best Electric Aircraft award went to Pipistrel’s Taurus Electro. *** There were some notable challengers in the category and three finalists: the Taurus, the Electric Cri-Cri (power by Electravia), and Eric Raymond’s Sunseeker II solar airplane. *** Also awarded was the Best Electric Propulsion. The two finalists were the LZ Design FES (Front Engine Sustainer) system and the Rapid 200 Fuel Cell propulsion system from Polytechnic Torino. *** The LZ FES was the winner. *** The LEAP 2011 Outstanding Achievement Award went to Bertrand Piccard, Andre Borschberg and the Solar Impulse Team for its electric around-the-world project airplane. *** A romantic, and apt, spin on the awards is linking today’s electric pioneers to Lucky Lindy’s amazing transatlantic flight in 1927, which pretty much singlehandedly changed the global perception of aviation from a daredevil hobby or foolhardy mail delivery system to the common transportation, recreational and warfare tool it has become.
Europe’s Aero 2011 in Full Swing
Aero Friedrichshafen, Europe’s big annual GA convention, has more than 600 exhibitors showing their wares and innovations right now through tomorrow. *** Sub-titled The Global Show for General Aviation, if you want to see what’s happening and what’s coming down the pike, you’ll not find a more intensely focused representation than at Aero. *** The show spreads displays from many big names and newcomers alike, up through bizjets, across its 11 big hangar-style display areas. *** I like this show, although lamentably I’ve yet to go, because it never fails to draw cool new stuff, in particular Microlight/LSA developments and electric and solar powered birds. Thousands of visitors flock to the “e-flight Expo” at Aero, in its third year as part of the show. *** Two big events will highlight the show this year: the Berblinger Flight Competition and the awarding of three LEAP prizes from Erik Lindbergh (Lucky Lindy’s grandson).
Aero 2011 Pre-Show Attention Getters
The major European Airshow, Aero, opened this morning with the usual unveiling of new designs but one aircraft appeared to be the center of attention. Peter Funk had an idea five years back but shelved it for other projects. Now the time is right for his distinctly retro treatment of one of Light-Sport aviation’s sharpest designs, the Fk14 Polaris (Alert readers will identify Polaris as the Cirrus SRS, that GA company’s onetime entry in the LSA sweepstakes.) *** Even experts accustomed to following the latest in new or updated designs were caught off guard by the unorthodox entry (photo). With dual windscreens and race car bodywork, the open cockpit creation charmed many who gained early access to the great exhibit halls of Aero… 11 of them, each the size of a gymnasium. While exhibitors were assembling their displays Fk Lightplanes’ staff grabbed lots of attention with their Fk14 Lemans. *** Constrained by their ongoing contract with Cirrus until the end of the year, Fk Lightplanes sought permission before revealing Lemans and sales will not happen in 2011.
Born in Eastern Europe, Raised in America: Allegro
One of the early success stories in Light-Sport aviation was the Allegro. The #3 Special LSA to be approved started out so strong that even after three years of no sales following the collapse of the Czech Fantasy Air company, Allegro still holds the #14 spot on the SLSA Market Share chart. When Fantasy Air ceased manufacturing many wrote off the metal wing, composite fuselage LSA. They judged too soon. *** Importers Doug and Betty Hempstead took a hit when Fantasy Air went down, but they picked each other up, dusted themselves off, and set a plan in motion to build the Allegro in America. The first effort went south when a west coast manufacturing facility closed its doors last year. Most folks would’ve given up for good, but Doug and Betty are tenacious aviation entrepreneurs. A few days after Sun ‘n Fun 2011, they went home and anxiously awaited a visit from the North Carolina governor.
