Thanks Josh
I have seen the S curve before. I dread the hole drilling part of this build. I started this project with discovering I have some things to learn about running a drill. I wish my drill had a built in level. the reinforcement plates that are on the ribs don't have a very big flange in which the rivets hold the flapperon brackets on. If I dont get these on straight and drill nearly absolutely perpendicular then the rivets will be awfully close to the edge. Thanks for your input.
