FlyBoy - I'm getting a Dirty Birdy for Christmas and will be building it for my winter project. Once completed, I'll have Joe Bridi's trio of Sunfli V, Utter Kaos, and the DB. Interesting to see the side-to-side comparisions of these models.

Apalsson - That is a good looking plane! I really like the tail section. Looks to be very stout.

I am now curious about the reason for the anhedral. There must be a reason other than what jsenicka suggests about the outside loop, as the full scale F-4 uses this configuration.
