P-18/Limited Penny Plane Ribs

A small sheet of laser cut ribs intended for P-18, Limited Penny Plane, and other light weight models. They are on a 1/16" thick sheet of 6 pound wood. This is a proven profile and is a real time saver if you are building your own designs. They allow for a wing with a five inch (129 mm) maximum chord. (New picture coming.)
