Cellophane tape is used to keep the hatch sides free from the fuselage sides as it is built in place. The sides of the hatch (above left) are aligned and held in place with pins. Once the initial box is constructed, the hatch is finished by gluing a sheet of 1


⁄16-inch balsa on top and allowed to dry. Blue tape (above right) is used to produce a simple mask. Rib R1 is used to trace its outline onto


the fuselage. With a new #11 blade, a careful cut inside the traced line is made. Once cut, carefully remove the outer material to reveal a mask (below left) that will aid in removing covering later. The motor mount (below right) has been mounted to the plywood firewall. Note the elongated slot for the motor wires and the two small holes for the hatch dowels.


When building the wing surfaces it is best to build off from the bottom spar. The airfoil is fully symmetrical so care must be made to not induce a warp into the wing (above) during construction. The horizontal stabilizer and elevator are simply built on top of the plans. The elevator can be built up as seen here (at right) or made from solid balsa and the airfoil sanded to shape.
