Two years ago at my favorite European airshow, Aero Friedrichshafen, Bill Canino of Sportair USA urged me to go look at a cool Part 103 project. With a general appearance resembling a Chance-Vought F4U Corsair military fighter, designer Jörg Hollmann‘s ultralight Corsair is reasonably authentic including its highly distinctive inverted gull wing design.
Two years ago when I saw the bare bones example - exhibited for this small shop design and manufacturing organization in BP Oil’s display stand - it was easy to get excited by the concept but less obvious to imagine how it might eventually look. At Aero 2018 the visual mystery was solved. Anyone who has admired F4U Corsair’s angular wings will be drawn to ultralight Corsair.
Even the engine mimics the original’s Pratt & Whitney R-2800 Double Wasp, except at ultralight weights and power. Jörg chose a three-cylinder Verner radial to power his diminutive aircraft. The whole package was fascinating to those of us who enjoy single seat designs.
The truly good news for Yankees who might want to own such a creation is that Sportair USA boss Bill has placed an initial order. For a tiny company, such a launch customer greatly increases the likelihood that this unqiue entry will makes it way into American skies. Of course, Europeans also recognize both the F4U resemblance and the coolness of this design effort.
While fabric covered (also for lightness), Jörg refers to his internal carbon fiber tube structure as “a unique carbon-spaceframe technology.” He added, “This property right-protected technology combines high strength with an unequaled low weight.”
Seeking a very low weight is partly a maneuver to steer clear of tough certification rules via the Part 103 / 120-Kilo Class / SSDR unregulations.
A light design permits Jörg’s design objectives. “Due to the light weight of the structure we were able to include all the ingredients for a high performance aircraft: outstanding aerodynamics, a strong engine with a big, efficient propeller, a short and aerodynamic landing gear, as well as effective flaperons.”
The carbon-spaceframe is effective, resulting in a calculated +9 and -6g ultimate load strength. “Furthermore,” Jörg said, “the complete cockpit area is constructed as a Kevlar-reinforced safety cell.” A ballistic parachute will further enhance safety.
In our article from 2016 we unveiled Corsair in bare carbon fiber bones. That article also repeated Jörg’s prediction that it would fly before Aero 2017. That didn’t happen, however, Jörg said it is now ready for flight. “Corsair would have flown before Aero 2018 but a lack of ideal weather prevented that. We prefer calm winds and clear weather for a first flight in such a light aircraft,” he explained. Because weather at Aero 2018 was warm and sunny, he hopes to get airborne in short order.
Not only can Corsair meet USA’s Part 103, it also can qualify for Germany’s 120-kilo class and Britain’s Single Seat DeRegulated (SSDR) class (article). Jörg explained, “Corsair currently fulfills the British SSDR regulation. An adapted version will comply to FAR Part 103.”
Although Corsair has ultralight proportions, it is versatile about pilots it can contain. “The ergonomics have been optimized with the help of our local flying club,” indicated Jörg. “It is suitable for pilots ranging from 5 feet 4 inches to 6 feet 8 inches (1.60-2 meters).” The inner cockpit is 23.6 inches wide (60 cm).
Corsair’s seat is adjustable in four length/height positions. The seat back incline is independently adjustable in 11 positions. Rudder pedals are also adjustable and even the joystick offers two positions.

Best looking 103 aircraft I ever saw!!!except rent and food I will save every dollar I earn no matter how long it takes to get my hands on this masterpiece!!
Thanks Dan Johnson, composite airframe is the way to go in "part 103" construction. What a beautiful aircraft. Excellent! Happy New Year to you and yours. J. Smith
Gotta love German engineering...This plane looks awesome.
The Corsair, a Naval warplane with an inverted gull wing, is a fascinating choice for an ultralight. When are you going to do a video on the Greek Archon Ultralight? An ultralight that resembles the latest warbirds.
This is one of those half million dollar "ultralights".
Looks great, though, and amazingly light.

Hi, as this is an Oratex-covered airplane, as mentioned in the video, the Oratex is marketed in North America by the company BetterAircraftFabric. The Oratex6000 is STC 'ed in USA and Canada and the AML contains about 150 types of aircraft, All Pipers, Maules, Huskies, etc. - If you are interested, visit the website or our You-tube-channel... Regards from Alaska!
Not quite whistling death, maybe whistling bruise.
Regardless it's a pretty sweet idea and makes me reconsider the purchase of an ultralight.
Legend Aircraft, beatiful!
You put the U in beaUtiful!!! LOL
Haha... I am sorry ... Beautiful !!!
All you need is a BIG audio system to replicate the sound of the PW R2800
Their website list a cruise speed of 168km/h. That's over 100m/h, much higher than part 103 limit, and empty weight is only 110kg, excellent work.
Probably with a prop swap or something
Thanks. Would be nicer to see more wide shots of the plane.
Can it be modded to look like a 109? or has it been modded to not look like one?
can the 3 cylinder be supercharged?
Clearly the plane has an adjustable seat.
With all of that carbon fiber does it become a hyper-ultralight?
This looks awesome, but I imagine the price will make it VERY unattractive given the materials used.

Tetractable gear ? It seems to be so but I don't think, because you would have mentioned.
DirkDucat It’s probably an option. In the US, it’s can’t be an ultralight with retracts, so since he said it would be part 103 compliant, it wouldn’t have retracts.
There is NO reason that an ultralight aircraft cannot have retractable gear in the U.S. It just has to meet the weight and stall criteria.
The Ultralight Flyer
Light Sport and Ultralight Flyer The aircraft could have it, but having retracts requires the correct licensing regardless of the aircraft’s classification. They would have to be locked out and inspected before it could be flown without a license and classified as part 103.
@@ultralightnews In Belgium it wouldn't pass.
@@adamr9215 AGAIN - AN ULTRALIGHT AIRCRAFT only has to meet weight and stall speed! Since there is NO license requirement - there also is NO endorsement required.
The Ultralight Flyer
Anyone know what the pricing is for this plane?
around $65k excl. tax, mostly due to CFRP construction and certified engine
Is there another video that shows how the carbon tubes are always held in tension?
That could be a trade secret.
@Tony Rusi There is no way all the tubes are in tension. I think what he said was the tows that made up the joints are always in tension.
P-38? Mosquito?😁😁😁😆
Too bad that engine is no longer in production.
I mean.... It's cool but for that price, no thanks.
I don't like the design. It doesn't look like a Corsair. Go to Dynodon64 on UA-cam. He built a miniature Corsair from supplies from Home Depot and an old Subaru engine with 150 h.p.. plus some old retractable landing gears he modified.
The plans for his Corsair are from the old War Aircraft Replicas. I have them too. Unfortunately, health brought mine to a screeching halt. Also, it is not an Ultralight.
Richard Browne That one isn’t an ultralight. This one is, and has to pass part 103 rules. That would require changes from the original design. This one can be flown without any license, but adding retracts would require a license and endorsements over a basic license.
An ultralight aircraft in the U.S. ONLY has to meet the weight and stall speed. Whether is has retract or not makes NO difference - I have flown a number of ultralight aircraft that have had retractable gear. There is NO endorsement, for retract, floats or anything else - just meet the weight and stall speed, and be limited to 5 gallons of fuel.
The Ultralight Flyer
Light Sport and Ultralight Flyer As it has been explained to me by 9 different FAA certified flight instructors and a&p’s who do annuals, retracts require a “complex aircraft” rating. To get a complex rating, you have to have at least a standard pilots license, LSA won’t cut it. It is required for any and all aircraft, regardless of its class. I was told that the aircraft could no longer be an ultralight, it would have to be an experimental, and have to follow all rules for registration, annuals etc. If I’ve been lied to, the FAA owes me a lot since this was an issue for me 15 years ago...
@@adamr9215 Oh by the way an ultralight is NOT an aircraft. It is an "ultralight vehicle"
This part prescribes rules governing the operation of ultralight vehicles in the United States. For the purposes of this part, an ultralight vehicle is a vehicle that:
1) Weighs less than 254 pounds empty weight, excluding floats and safety devices which are intended for deployment in a potentially catastrophic situation;
(2) Has a fuel capacity not exceeding 5 U.S. gallons;
(3) Is not capable of more than 55 knots calibrated airspeed at full power in level flight; and
(4) Has a power-off stall speed which does not exceed 24 knots calibrated airspeed.
