Minor detail, but I checked the underside of the wings through the photos up on IG (I originally made suggestions to NG and it's in one of Richard's articles also). Looks like they did make some change from the sample mould but they for some reason just copied the details from the 748... Not the end of the world but that means the flaps are incorrect as the 748 has a different flap design.
Can't quite see the top side of the wings with NG's photos. If anyone can post a top view photo later that would be much appreciated. If they copied the 748 config on the top side too, that needs to be fixed immediately.
