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 For 707. It is to be put unto the interior. I don't recommend doing the cockpit. So just use those. I will make a collection for making it easier for you. I hope it won't get more than 2Mb.
