@Mudzin:
Actually the cockpit is what takes probably most of the time. And it's not the funny part of making such a model. I think Fred was working about 5 weeks per cockpit, but these were his firsts (which of course ends in a lot of additional time). You can imagine that these little details take sometimes more work then making a large but much simpler object.
So a huge congrats to Fred for all the cockpits he finalised.
