That's the file I used. Like I said it was lumpy and lacked detail, especially around the wingtips. I essentially cut off the wing tips and then added my own wing-grid, spanning the "tip feathers" to approximate the wing profile and using the images from the video to eyeball the vertical spread of the grid.
@henryk : I like the idea of flapping wing propulsion. I think it has vastly more potential than propellers. However, there is a lot of work that needs to be done to make flapping technology functional. One big obstacle, as I see it, is the landing gear. Flapping wings and a fixed rolling undercarriage don't mix. Something has to be done to accommodate the wings' flapping on takeoff, or it will never achieve an effective level of operation. I can see using wheels on the ground, but at a minimum, it will need some kind of leg that moves in coordination with the flapping.
Better still is to skip the wheel and just make it run. That used to be a very sci-fi proposition, but the folks at Boston Dynamics seem to have made significant progress on that front. Maybe it isn't that sci-fi of an idea any more.
The other option is to use the wings for the landing gear, and do a jump takeoff like a pterosaur. It will need the ability to release a big jolt of energy for the jump, but the landing-gear/leg problem largely goes away and you get the added benefit of a zero-roll jump takeoff. It would make the ultimate STOL bush-plane.
