Yes, but like I said, I wasn't smart enough to put the rudder inside the wing planform, thus my experimenting had shorter relative cords, which made it hard to get an adequate wing area.Those are very helpful comments, StarJar. I wonder if you have messed around with any other low AR shapes in Xflr5? Square, delta, Zimmerman, D, etc?

More footage of the "Flying Flounder" above (first 60 seconds of the video anyway). The landing and the takeoff really show how much AOA they can handle. ...and the complete lack of visibility at high AOA. To take advantage of what a very low AR wing can do, I think the pilot needs to be under the wing.And some people find an aspect ratio of 1.0 to be too...high!
The flying stop sign is ALMOST a top contender. If you change that outer leading edge angle from 45° to 50°, you should get the vortex lift.
This lines up with something I was thinking about before. Essentially a gyrocopter with a disk wing on top instead of a rotor. Having the disk wing on a gimbal also makes it easy to design and experiment with since you can just copy a standard gyrocopter with minimal changes.
I really don't think you want a "free wing" on a Nemeth-type parasol, meaning the wing seeks it's own best angle of attack so you'd need the pitch control on the rear of the wing with perhaps a fixed horizontal stab to keep the fuselage aligned with the airflow. On the other hand, a variable-incidence wing with the pitch control still at the tail but the main wing incidence variable (though fixed at any given moment) might work well and would not be hard in a strut-braced parasol. Supermarine Dumbo meets Flying Flea meets Nemeth Umbrellaplane!What are the advantages/disadvantages of putting the engine on the LE vs. the nose of the fuselage?
I'm thinking a parasol with the disk mounted as a "free wing" might solve some of the high AOA issues on landing. ie. tilt the whole disk up about 20 degrees for landing.
That would go really nicely with the Art Deco styling I've been getting into lately.I'm kind of thinking in this direction.
Between the high wing, parachuting effect, big tires, and protected pusher prop you could land this thing darn near anywhere.
Only two-axis controls but the rudder and pendulum effect would give you a little proverse roll when yawing.
