Hello,
this is going to become a model undergoing nice changes over time
The radio cables have even their connections to the transmitter
The flag is now on a mast. However, the main mast (in case of a two-mast ship the aft/rear mast !!) carries the flag not the foremast (whatever the size). Have look a the main mast of the civil version -- it has a small longitudinal yardarm pointing aft and a bit up. This yardarm is no crane. It has just one purpose -- it carries the cable the flag is attachted to.
To give you an idea what I mean:
