Construction

Cut out the paterns and transfer them to the foam and cut out the shapes. Cut a 1" wide strip of plastic across a 4 gallon trash bag. This strip will be about 17 1/4" long. Open the strip and lay it over the point of the body. Push a 1/2" nnail through the plastic and into the foam along the edge. Gently stretch the rest of the plastic over the circumference of the body. Pull the plastic down so the edge is even with the top of the body. Push a nail into the foam about every 2 inches around the perimeter.

Glue the support triangles on each side of the opening in the hull. Glue the motor support in place and glue or tie the motor in the center. Push the propeller on the shaft. Glue the fin 1/4" to the right of the center line starting at the back of the body. Make a battery holder by rolling 2 AA batteries in the 5x8 paper. Roll one time around the batteries, spread white glue in thin streaks on the rest of the paper and roll tight. Crumple a piece of aluminum foil and push in one end of the tube. Wrap an insulated wire end around a straight pin and push the pin through the paper tube and into the foil. Put another piece of foil in the other end of the tube leaving some of it sticking out the end. Wrap a rubber band lengthwise around the assembly to make good connections. Wrap another wire end around the other pin and lead to the motor. After hooking the wires to the motor, stick the pin into the exposed foil to make the motor run. If wind blows forward, reverse the wire hookups on the motor or on the battery pack.

The model will run well on smooth surfaces. The batteries can be moved around for best balance and best speed. The fin can be bent for turning or straight running. Keep experimenting by trying more batteries, carrying a load, or speed testing. Have fun!
