This beautiful airplane, the Avanti II (600mb CAD) model (rendered in Blender), focuses on exterior aerodynamic surfaces. The fuselage, other than other Avanti models available on the internet that is approximation surfaces (even if a factory plan is used to construct it), is the correct mathematical derivative, as it was originally intended for the real life design. In so far as the real fabricated plane diverts from this in real life - in so much it becomes imperfect. Therefore this part of the model makes for the perfect base for new airplane design. Real life airfoils is chosen for all other lifting surfaces. The engine cowls are deliberately and properly blended airfoil sections - therefore very slightly departing from the real. Care has been taken to make the landing gear as original as possible although it has my take on it to make it strong and light. This is the upgraded version of the undercarriage. The propellers consists of both the original and new upgraded Evo models. No other structural, interior or other moving mechanisms is included, as it was not the focus. Keycreator and Designspark Mechanical files are included, also translated into STEP ans SAT. For rendering programs STL & Obj and Blender files are included. Others is available on request. The files are huge. The polygon and vertice count are large because of its accuracy. However, some of the render files have far less polygons and vertices as the wire-frame pictures show. However, one low(er) poly .obj version of 40mb is uploaded.
