An experiment, which was abandoned due too little to no interest in the design and goals not completely met. Theses flights were on a farm hay field fairly rough and bumpy which is why I had ballon tires on it. Flew ok, just to heavy and faster than an ultralight should be. It was interesting. Wing span was 17 feet and cord a bit over 7 foot. The wings outer panel folded down towards the ground. Year was 1998 I believe. Craft was cannibalized for its engine, etc and taken out of service.

Much respect for the little motor pulling all that drag around the sky.

" all that drag " how much drag do you think it had, and what do you think was the cause of the drag ? It was too fast for part 103 with a Kawasaki 340 if I recall correctly so I doubt it had a lot of drag. Certainly looks less draggy than a trike and wing weight shift aircraft or a powered parachute or a open frame gyro.

You think? So the exaggerated chord length, camber and incidence angle of the aerofoil produce minimal drag? The aerodynamic efficiency at that steep angle of attack in level flight must be excellent for sure. Much respect for the little motor pulling all that drag around the sky!

Roger Mann wrote " it was a very fast aircraft in level flight.....not seen in video much." So yes, not that much drag, unless the pilot is using the high A wing-tip vortex-driven "parachute lift" to fly super-slowly. This "parachute lift" is seen in the 1930s Arup, and Nemeth, and the Farman 1020, in the '40s Eshelman and the Vought V-173, in the '80s Hatfield "little Bird" and the '90s "Facetmobile.. All of these have demonstrated super-slow stall-proof flight and efficiency at cruise. The extreme drag caused by the parachute lift phenomenon is elective and temporary.

Some of the Farman-inspired biplanes of pre-WWI and during WWI were not only single-surface but had single wire control of ailerons. On the ground the ailerons hung straight down. Air flow was what pushed them up. Yet they flew.

Individual results may vary, and mechanics and iteration of a concept make the difference, but a common misconception seen everywhere and here in these comments is that a very low aspect ratio must have very high drag. Very many examples have shown this to be false as a rule. Many have proven to be sleek and quick on available power. See the '30s Nemeth "parachute plane". Biplane fuselage with a 15' diameter parasol wing. Faster than the original, 45 degree climb, 60 degree descent with near-zero landing roll in any wid. Stall-spin proof. Similar to the '30s Farman 1020, also faster than the monoplane which the fuselage came from, similar abilities and stall-proof. Most famous, the Arup plane from Indiana ("Air + Up"). S-2 was the basis for the Vought V-173, and proved that it did not need the over-complex situation with the props (NACA tunnel tests with the Vought / Zimmerman plane found that it did not gain anything from that situation of the props)>Arup S-2 was 790 lbs, flew 85 kts on 37 hp,

sorry, bit the litzle bird has a low wing loading to fulfill §103 and is basically a plank! 🤷‍♀️sorry, i worked on a design for 1,5 yrs bcs of those partly overemphaziced infos! the Arup 2 had a stall speed of 20 knots...sure? anyone ever measured that? and they landed into the wond on ooen plain dry ground, bcs the rudders were compketely ineffcient at high AOA, i spent just 6 months now on calculating and reevaluating data from the net! does anyone really believe a parasole airplane made stalls at 22 knots with wing loadings over 25 kilos/m2 ? the fokker E3,3/4 replica scale has a winloading of 24,4 kg/m2 and "just fulfills"§103...they have a starer on the engine, yes..but thats it! and do they sell? no engine in a kit for 7 grands...🤷‍♀️if you calculate the lift on the airfoils they use that all never works, only low AR shapes can make a big virtx like a parachute...but look for data...you won,t find any! Pleuchel ladder tandem...off the market, all 1930-40 tandems off the market, Rutan quickies,,,,died out bcs the data was not proving the expected results...they fly well and safe, yes...but not as slow as expected... and ever tried to find out about an Arup S4 wing spar areangement and mchanics, when 2/3 of the load are spread on the inner half of the wing and all is an uneven parabolic load? yes? ever tried thta? otherwise you overbuild and can.t break the weight limit🤷‍♀️and don,t firget, most of those hardly wver git into more than 2 G and didn,t ever prove that they fulfill any safety margine! when you build safe and calculate the loads and try it out you ALWAYS bust the miraculos 24 kts range...always! itls simply too narrow for any serious construction, the flimsy shit they applied it to was a desth trap made of aluminium tubing with mo proving, and no safe G margine! 🤷‍♀️good luck, we all search on,..but tha highes wingloading currently is about24,4 kilos/ m2 for 24kts stall, and this was "estimated" as pitot tubes don,t work at an AOA 16 degress or more! 🤷‍♀️sorry...maybe i wasted 2 yrs on that and 5000 bucks,,

@@SR-gs8zo What you believe is irrelevant to the facts of history. Yes, the Arup and the Nemeth and others like the Facetmobile were measured and found to have super-sly speeds and to be resistant to or proof against stalling. Sorry it you don't "believe" it. The Arups and the Nemeth didn't have to conform to any part 103 rules, so that's irrelevant.
