How to Make Two Part Fiberglass Molds of a RC Plane

It is not difficult to make two part fiberglass molds of a RC plane. Fiberglass is the important element utilized to support the wings of the RC airplane. Fiberglass is a hard-wearing material, which matches well for the fuselages in the airplane. The wings of the RC plane are generally made with foam.

  • Tack cloth
  • Fiberglass cloth
  • Scissors

Instructions

    • 1

      Place the release agent on the mold. You will need to do this in order to detach the completed fiberglass section from your mold. Confirm that you have a right and left side mold for the plane's fuselage. Sever fiberglass cloth into strips and lay them carefully inside of the molds. Do not lay the strips in the identical directions. The parts strength is increased when you vary the direction of the fiberglass cloth. Be certain every piece goes past the outer edge of the mold.

      Use a paintbrush to apply the resin to the fiberglass. Let the resin sit in a cool, dry place for four hours, allowing it to dry completely. Confirm that each part is dry. Take the parts off the mold.

    • 3

      Utilize the epoxy in order to glue the plywood formers to half of the fuselage. The sandpaper should be used on the piece of fiberglass in order to ensure greater adhesion. Use the epoxy on the surface in order to attach the fuselage halves. The rubber bands should be used to keep the pieces together until the epoxy completely hardens.

    • 4

      Sever two strips of fiberglass cloth. Make certain that they are ½-inch wide. Put the strips on the sections where fiberglass touches. Utilize the resin and slowly pour it over the cloth. Use the sandpaper to smooth all the edges when the resin dries.

    • 5

      Use tack cloth to get rid of foam dust. Utilize the epoxy in order to lock the fiberglass to the pinnacle of the foam wing.
