Hi Martin, I don't remember something special about F11. The thing is when you will glue the formers against the 2 wing parts it is better to use white glue than cyano. I made the mistake to first glue all the formers against one wing side with cyano, and when I tried to join with the second wing some of the formers where not well aligned and I had to remove the glue on these formers (I broke some parts in the operation). So if you use white glue it will allow you to take your time to aligne everything well because the glue will dry slowly.
Bad news for your fan 64mm.. I have bought from bangood 4 fms fans (the ones used on Tony's Concorde).
