The tube that creates the airfoil curve is the same part number. Draw your own conclusions.
How about a UL Buhl Pup replica?

I'm curious too. Seems counter intuitive, but then there is a lot connected with our hobby that is.
Could it be related to the rate of deceleration vs AOA change leading up to the stall that 'tricks' the airspeed indicator?

I seem to have forgotten to throw any textbooks in my bag, does anyone have a method of calculating stall speed of a rectangular wing for dummies?

Calling @cluttonfred do you still have the information on hand for a little cable-braced French(?) monoplane you posted elsewhere a few months back?

Not Matthew, but I believe it was the Farman Moustique.
It goes back more than a decade, not a few months, but is this what you meant?
Interest in a modern incarnation of the Farman F.455 Moustique?
I have been kicking around ideas for a light, two-seat homebuilt that would fit within the European microlight rules (basically, stall speed below 65 kph/35 knots and gross weight under 450 kg/992 lbs). I'd use a 60-80 hp VW engine, a wood prop and simple construction for first-time builders...

Maybe someone else posted but I thought there was something a little newer, maybe made sometime between the 70s and now. I think it was posted within the last six months but the way the last two years have gone, who knows?

Found it! It was the Starck A.S. 90 “New Look” I was thinking of.
Ah , yes, that's a fun one, too!

Here’s a quick copy of the Starck’s specs:
If my high school French holds, it tells us it has 18hp (unless France used a different power standard?). I think it also has a span of 7.4m (24-ish feet), length 5.35m (17.5 feet), 9.4m^2 wing area (101 square feet), empty weight 120kg (264lb), and a max gross weight of 210kg (463lb). The useful load kind of sucks but such is life.
Performance appears to be max speed(?) 90km/h (56mph), cruise speed 80km/h (50mph), I assume the next one is stall at 35km/h (22mph!), and possibly ceiling and range respectively at 3000m (10,000 feet, give or take) and 200km (125 statute miles).
All up, those are very 103-ish specs in an airplane designed on another continent a decade or more before the FAA put pen to paper on their own rules.
It’s a neat design. In other drawings I have seen the ailerons appeared to be offset below the trailing edge for a slotted effect but I don’t think I have ever seen a good photo to confirm that. The Aubier & Dunne engine was used in another early famous French ultralight…the original Mignet HM.14 Pou-du-Ciel or Flying Flea.

Was the Aubier & Dunne engine similar to the Scott Flying Squirrel?
I believe that the Scott Flying Squirrel was a British motorcycle maker’s attempt to capitalize on the Flying Flea craze and general interest in ultalight aircraft by creating a domestic UK alternative to the Aubier & Dunne.
