This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This contains landing gear, more larger fuselage (which is wider and higher for passenger comfortness and coziness, but a little shorter), longer/wider wings, and, just a little tail edit. This design would be more efficient due to the factor of wideness. Wider, makes a little more easy dynamics, and it has also wings moved back just about 5-10 feet for maintaining the efficiency. Now, the interior would be wider. This also feautures more gear for proper landings. EDIT: Woohoo! I forget to give credit in 49%25 of all my latest models! Thanx to AN777. @AN777: Ok you got a point. But, how hard the cross section was, the nose is too long.
