hi John...
I did make separate tabs for the cowlings and so maybe that made them slightly more curvy. I was pleased how they turned out, though, and really like this constructions vs. the tulips I've seen in others. I think you must have designed it spot on.
By the way...I just got "Tinkertoy", "Boilermaker II" and "Dragon and His Tail". I plan on making these into 1/72nd ships and will see about bomb bay opening etc. and leave you a play-by-play.
I've been enamored with "Tinkertoy" since seeing that photo in "The Mighty Eighth" showing the fellow pointing to the shell holes in the canopy. Chilling. Neat to see someone modeled this one.
Cheers and have a great weekend,
Dan
