We have been looking at the differences between the coordinates given in the plans and the full size rib template that is provided with each set of plans. There seems to be a conflict between the rear spar fitting within the plotted coordinates and the template. A little more time is going to be needed to sort this detail out before we start building our wing rib jigs.
Below are three airfoil profiles based on the original coordinates provided in the magazine article for building the Air Camper, the measured coordinates based on the template provided with the plans we purcahsed and what I am calling the Smoothed Airfoil where the 4-3/4" spars fit accurately within the airfoil and any bumps in the profile have been smoothed out.
