Thanks Larry,

I've got 1/8" dowel and round tooth picks. Gonna test my precision drilling technique. I was also considering constructing truss-type counters using somewhat denser balsa. I've got some 1" x 1/4 for the leading and trailing edges with 1/4 x 1/4 side rails and 1/8 x 1/4 cross structure. Hey, it's Sunday and the weathers stinks (for flying). So it's off to the dungeon ...
