RE: Pentathlon Kit Build
With all of the foam core pieces sheeted and finished (except for the wing and stab roots), work can begin on the fuselage frame. The fuse sides should be dry assembled against a straight edge. Once glued together, the 1/16" ply doubler will be laid on the inside surface of its respective fuse side at the nose (do NOT glue) in order to mark where it ends. From this point (right behind the landing gear former) all the way to the tail, we will add some 1/16" balsa doubler material. On my prototype, I sheeted the entire inside surface to the tail (cross-grain). In this build, I will only be placing the 1/16" balsa along the top and bottom edges, and at each former location (vertical slots).
