The ribs of both wing halves have been glued to the LE and TE wooden dowels. Pinning the front dowel to the plans first, and then gluing and pinning the front of each rib to the dowel, works well.


edge) wooden dowels. Pinning the front dowel to the plans before gluing and pinning the front of each rib to the dowel works well. Then, lay the rear dowel up against the rear of all of the ribs. Put a dab of glue into each spot where it will contact a rib, and then roll the rear dowel forward to glue it to all of the ribs at the same time. Also in this step, add in the diagonal ribs. When the wings have dried, add the wingtip support pieces to the outer three ribs. The wingtip pieces will need a bit of sanding as they are joined. Let the glue dry between each step of the five-step operation. Pin the left wing to the building


board, and make sure the wings touch each other at the end of the dowels. Put a 2-inch spacer 51


/2 inches from the


center of the wings under the right wing to space it up for 20° of dihedral (I used two VHS tapes). When that has dried, glue in the four light plywood wing mounts, then sand the wingtips on both sides.


This is a good time to glue in the strut mounts, and use the 1

balsa strut mount jig to get the correct angle. Make sure that you install the #2-56 blind nuts into the strut mounts before covering the wing, because it will be impossible to do so later. For the fuselage,

vertical for this step. When that has dried, glue in the 1


/8 -inch plywood strut suspension mounts have 1/16 /8 -inch scrap


spacers under them. The firewall itself has 1


-inch spacers beneath it. The two nose pieces are glued to the


firewall, and the motor mount is glued to the nose pieces. Put the nose piece on the right side as indicated on the drawing to provide some right thrust, which is helpful on takeoff. The firewall should be spaced up with a 1


/8 -inch-


thick piece of scrap wood. Add the ESC mount when the nose pieces have dried to the firewall. Cut the 7


/16 dowel to proper length


and flatten the rear with either a sander or a scroll saw so that you have a flat area to glue on the tail mounts. Glue them on along with the tail skid support. To keep the firewall perpendicular


to the fuselage stick, I used the VHS tapes and a crack in my flooring. The alignment tool holds the rear of the fuselage at the elevator servo mount location. The 1

mounts on both sides. Next is the camera mount. The vertical balsa support pieces should be spaced exactly 13

each other. Epoxy in place the small galvanized plate that accommodates the Polaroid Cube’s magnetic mount. The 1

-inch diameter hole in the center can accommodate a small point-and-shoot camera such as a Sony Cyber-shot (Sony.net), which can shoot 1080p HD video. It should be noted that the Sony camera weighs roughly 41

ounces, whereas the Polaroid Cube /2

will vary depending on the camera you choose, and the takeoff distance is considerably longer with the heavier camera. The wing mounts should be glued in /2


at an 111 /4


-inch spacing, as shown on the


drawing. It is easier to first glue the wing mounts together as a subassembly. For the battery, I glued in a 1-inch-long, 1


-inch -inch plywood pieces (number


dowel into the front hole to anchor an elastic to retain the battery in flight. This entire battery mount can be glued on top of the 7


/16 -inch dowel fuselage stick, to


attain the correct CG (center of gravity) in the range shown on the drawing. I measured my CG to go with the


lighter-weight Polaroid Cube. When I attach the heavier camera, the CG is moved forward slightly, but it does not seem to hurt the model’s flying qualities. Don’t do the final gluing of the battery


The wing halves are glued together with the dihedral joiners. Pin the left wing half to the building board, and make sure the wing halves touch each other at the end of the dowels. Put a 2-inch spacer 5.5 inches from the center of the wing under the right wing to space it up for 20° dihedral.
