One of my most unforgetable memories is how precisely solid and stable Joe Bridi's Dirty Birdy seemed to fly through the pattern at Lake Charles in the mid '70s. Out of all the great flyers that I observed back then, those JB/DB flights left the longest lasting impression. He surely knew a secret or two about how to set up (and fly) an RC pattern ship. I'm gonna build my (at least the first one) Dirty Birdy to that spec.
It seems similar, to me, to the way B. Hebert advises to set up a plane with some 'triangulation' to create solid, predictable flight behavior. Works on planes on G3.5.

My theory is that if you were able to go back in time and check Joe's original models, you would find that they differ from the specs shown today. Master pattern pilots seldom shared their flying secrets, and especially back then.
