So I got my homemade RC plane just about done. The following photos illustrate. I had to make a change, by moving the wing farther back so I could get a reasonable cg location without adding a lot of nose weight.
While working on this plane I realized that there is an easy way to build an airfoil using Dow blue foam and foam core board. The method can produce symmetrical, under-cambered, or flat-bottomed wings. All I have to do now is locate the correct blue foam, which does not seem to be used very much in this area. I can get all the pink stuff I want but that does not allow sanding. I need stuff I can sand, in order to shape the leading edge.
