@ RayBlender: Thanks for the images and the explanation 
Looks quite helpful to me.
Being an aviation fan I can only be amazed by (another) great aircraft model.
I only wish someone could pick up one of these detailed models (thinking of mrys models also) and make a detailed tutorial.
I finished the plane and started some scene (more information on my Blog)
What do you think about it?
i love the reflections on the wings
very photorealistic
though it looks to me like the ground isn’t quite right, almost like it’s not “slipping away” at the right angle
or was that intended?
It was intended that ther is no motion blur because this would be very difficult to achieve in reality. And photorealism definitely is an aim here.
