Wing Construction Page 4

 

When I was finished putting on the leading edge plywood I noticed in some areas there was a slight wave in the plywood on the top side between the ribs in just a few places. I talked to Mike Makepeace about this. He told me that this does happen from time to time and suggested that I scallop the top front leading edge. If I didn't have this problem now, I could have had this wave in the plywood anyway when the fabric is shrunk. Putting a scallop in the leading edge would eliminate this from happening and I would have a nicer finished look to the wing.

 

 

Another item you will install on the wing I will call the fabric bracing. It is 1/8" X1" strips of plywood. They go on the ends of the wings, aleron and flaps. These give you a nicer finish but there main pourpos is to keep your wing from warping when your shrinking your fabric.

 

Something that took me a long time to do was to fit the aileron. My wood file and quite a bit of sandpaper got a lot of use during this process. It just takes some time to have it all fit right.

 

This is a route end view of the aleron attached to the wing. At the bottom of the photo youi can see where the fabric bracing has been installed on the aileron and not on the flap. On the flap side it is a solid wing. I did not build the flaps for this 303. You can also see the aleron control arm. The control for the aileron are tubes and not cables.
