How to Build a Large RC Plane

Building a large remote control plane is different from building a smaller plane because you must make sure that the struts are securely affixed to support the greater weight. To that end, you will need to use epoxy resin adhesives to glue the struts down (Epoxy resins are the strongest and most resilient of non-industrial glues.). You must also be careful to waterproof the plane. If the remote control plane is caught out in the rain it can easily lose lift due to water seeping inside of the chassis.

Things You'll Need

  • Epoxy resin
  • Wooden stirring rod
  • Spray on weatherizer
  • Sandwich bag
  • Safety goggles

Instructions

    • 1

      Lay the plane parts out, separating the parts into like-piles. You will need a large workspace--six foot wide by five foot deep at least. If you are assembling an exceptionally large plane, you may need to clear out an entire garage and use the floor as an assembly space. Be careful to place the delicate parts to the side, to prevent damaging them with a misplaced hand. Lay the instructions out on a separate table so that the paper does not occlude your vision of the parts laid out in your workspace.

      Follow the instructions as they are laid out. Do not deviate from the instructions because every piece is vitally important to supporting the additional bulk of the remote control plane. Use a two-stage epoxy resin to secure the struts. The epoxy resin will come in a syringe with two vials in it. As you push the plunger down, the two chemicals will mix at the tip to form the epoxy resin. Hold each freshly glued part to the part that you are securing it to for half a minute to allow the adhesive time to cure. Epoxy resin cures at room temperature, so do not use a blow dryer or other heat source because this may damage some of the more delicate components.

      Spread a light covering of epoxy resin on the seams of the plane after the exterior is fully assembled. Use a wooden stirring rod or craft stick to take the epoxy resin off the tip of the applicator and spread it over the seam in an even covering. This will help seal the skin of the plane from any water leaks. Because of your plane's larger internal volume, you must be careful not to get debris or water inside of it. Debris or water may unbalance the plane, rendering it uncontrollable and unflyable.

      Once the plane is fully assembled, place a plastic sandwich bag over the engine and tape it tightly down. You must protect the engine from the spray on weatherizer to avoid sealing up a vital port. Put on a pair of safety goggles, and then spay down the plane with the weatherizer to waterproof the skin of the plane. The epoxy resin sealed up the seams but the weatherizer will seal up the microscopic pores in the plane. Wait for an hour to allow the weatherizer to set, and then take the sandwich bag off and fly your large plane, even in the rain.
