Here are some images of Incunabula Museum series il volo instrumentale Da Vinci's Flying Machine. In its configuration Da Vinci's Flying Machine would not have flown however I think that if one were to flip the wing spars up 90 degrees and if one were to get rid of that flapping wing idea it just might fly. This model was a very fun build and not as difficult as it may first seem. Well worth the buy if you come across one. If you wish to buy this kit online you can do so here.
