I tried to recreate Bell vtol Valor,but mine is more rounded fuselage.Rotors was designed like most vtols.I changed front wings design a little bit.All created with Moi3d CAD 3d modeling software.I uploaded it with NGONs version too,if you need it for 3d project

There are 6 solids watertight objects.First is fuselage with windows and wings parts

Propellers detached from engines with holes extrusion with small gap,so it could spin.

Engines can rotate and there is smaller gap where it connects with the wings
