RB - These mods are brilliant.
There are just a couple of questions I have. On the 7c why aren't you using the jack staff at the aft end of the conning tower (similar to the link image at the bottom of your postings)? I have never seen flags flying either side of the bandstand in photos. Will you be giving people a choice as you did with the 7b?
Is there a way of slowing down the flapping of the flag?
Is there a way of "drooping" the flag when the sub is stopped - possibly a very challenging request - hence the challenge
Please keep up the good work.
