A note on the Cold Duck Dynamic Balsa wing cores:

On the “New Duck” I built the ailerons into the wing, rather than using the original tacked on tapered strip ailerons that were 1 ½” at the root and 1” at the tip. The new ailerons are 1 ½” all the way to the tip. To do this I eliminated the 3/8” piece on the tailing edge and had to cut a small amount of the trailing edge of the wing off to provide some space for the new aileron width. I made the cut after I sheeted the wing and then I caped the trailing edge with 1/16” hard balsa. The wing tip ended up about 9 1/2” wide rather than the original 9 ¼” and the new root is about 11 ¾”. The wing core is easy to cut with a straight edge and #11 blade. I find taping the straight edge down to the wing with masking tape helps hold it in place while cutting. The new ailerons start 6” out from the root and stop 2” from the tip. With the much higher speed of the new duck it is probably a good idea not to run the ailerons all the way to the wing tip.
