I call this the BWB Mray Drone. This is one of several BWB models, tested in XFLR5 to fly stabe without trim with a CG calculated as if all was made of one material like for instance foam. This one has a wide body, with large capacity to load. If motors was added on top of the back, the cg is to shift. A CAD file with the specially developed slightly positive cm & low drag low Reynolds profiles in position is available as .step & .sat CAD files. This model is flyable. Lots of possible control surfaces is shown
