RE: BlueJay Dirty Birdy outline is not accurate to RCM plans.
What Bluejay is is the last Joe Bridi company. He would build a company and sell it; he would design something and sell it, but he would always carry the same designs with him with enough changes to not step on toes. Remember Great Planes started by buying out Bridi in the late 70's. Magazine plans would be the original while each iteration after and conversion to kit always dilute the designs.
