" 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!

@@jacktar4421 IDK about this individual plane, but the very low aspect-ratio type does not need to always fly at such steep _*A*_, very slowly. Many of aspect ratio

@@rogermann1855 Ok Roger. No drag then. Thanks.

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.

@@rogermann1855 it was a great vid, trawling KZfaq for nice content after an op knocked me of my feet for a few weeks.

@@chrisjohnson3590 yep, thanks and best! Roger

Kinda ugly but it flys

Why the odd paint.....so i had a bunch of leftovers. So not knowing how it would do i threw all these at her. Kind of wh iij ch i still had her now... oh wait...i do!

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.

Shoulda mounted that prop vertically and used it to cut the grass in the field.

exactly...🤷‍♀️but what they bash is the field..not the plane🤣

a bit too heavy and fast is mostly the reason why so many Ul designs end as experimentals!

basically is a blank, just with som close coupled tail...so where is the line to draw?

@@SR-gs8zo it seems to fly quite well... Many low aspect designs do, although standard aerodynamics says they shouldn't.....

no, he didn.t prey and didn,t ask for money...

With such a short fuselage the rudder does not have much leverage. A bit bigger would be better.

High alpha only if flown very slowly. Normal AoA in cruise.

High wing, so the aircraft has pendulum stability.

@@alanmawson9601 . . . and no dihedral.

Yes obviously ,you moron

@@manifold1476 yup!

yes, but that would have lost 2/3 of it.s weight to make 24 kts stall speed...it had a wingloading of 50+ kg at 48 kts!

So what was that thing you saw flying ? You moron

This was flown slowly on purpose, it cruises normal AoA.
