I liked the look of my Goldberg/Brodak Shoestring profile in the air, so i decided to build a slightly larger size with flaps. This is not an enlarged build off the original plans, but my interpretation of what i thought a larger Shoestring would look like. I used the moments off my other stunt planes, along with an airfoil that is fairly thick. OS 46 LA for power, 52" WS, butyrate dope finish. I did a build thread on another site ( not sure if i can name it here or not). I just retired and am building up a storm these days! Too windy around here to fly right now. last pic of size difference between the two. Hope the pics post....Gene
