John Ostrom asked me to do just that shortly before the Ostrom symposium several years ago. If I remember correctly, some quickly done flapping calculations indicated that it sould be capable of decent flapping flight performance given a pectoral mass fraction of roughly about 7% (about half that of a typical modern bird). It didn't glide too well -- about 2/3 the gliding performance of a pigeon unless the tail was cascadable, in which case performance would have been substantially improved. I have no idea whether the tail was cascadable though. I also did some rather elementary launch calculations that convinced me that it would be able to launch from the ground without significant difficulty (though I didn't buy into the Burger [sp??] ground effect vs. speed hypothesis).

Any chance of a paper being published on this?

Not by me :-) I did it as a favor, on a subject I'm not terribly interested in.
