OK, here it is with flaps. Original configuration with 2215/2206 without washout. There are no split flaps in the program, only plain flaps, here set to 45 degrees deflection. The classic VLM method didn't work, so it's Quads. Don't know if the results are comparable now, but they look reasonable.

It's as expected: smooth stall beginning at root and progressing to the tips, over a span of 4 degrees of aoa. But: These are rather small aoas. First picture is for aoa=3, meaning the fuselage is level. The second picture is for aoa=6, just before stall, which begins at aoa=7 and is complete at aoa=10. That's not bad at all. It confirms that the tip-stall problem vanished and the plane stays controllable as well as that no three-point landing is possible.

The pictures look rather messy, showing some strange (?) things. There seems to be a negative induced drag where the ailerons are. Much uneven viscous drag behind the flaps. Strong vortices at the flap-aileron break. Doesn't look wrong, though.

The aoas look similar in the simulator, but the stall seems to be somewhat indifferent and looks like a tip stall. The model is controllable though, like a 3D pattern model which can do no steady harrier. I wonder which simplified stall model the simulator uses to get this behavior. Oh well.

An afterthought: The rear view with streamlines clearly shows any vortices. The "clean" wing at aoa=8 also looks clean, no vortices except at the tips. The "dirty" configuration also looks dirty with many vortices, especially of course at the flaps-aileron break. But the whole outer wing panels with the ailerons have small vortices as well. Maybe that's why the airplane seems so wavery, not knowing whether to fly left or right. Over-interpretation?
