The GP4 that George Pereira flies has a layer of 5.?? OZ cloth covering the wings, the GP5 that "almost" raced at Reno this year is built the same way, except it has two layers of cloth over 1/16th inch mahogany 45 degree ply. It has been clocked at over 435 MPH before the engine blew.....

They are still in the shop so I will weigh them/it (single piece wing). We are contemplating a layer of glass for weather protection tho. I am not sure that the GP4 calls for a glass coat. The lateWhitman recomended the glass layer for ply wings as a protective measure. Didn't the Falco have tapered ply covered wings?
