There is a floor set by Reynolds number, somewhere around walking speed, with the upper limit around 250 MPH. aerohead will have the citations.
Still can't remember the other example. It's a bubble canopy with a shark mouth air intake directly behind, rather than extended around the sides like the X-47. A NACA duct would be more efficient but lack the opportunity to revise the loft line.
