How to Build a RC Model Airplane
- 1). Buy an EPP RC model airplane kit online or from a hobby shop.
- 2). Sand the airplane parts using the foam pieces themselves to sand with. Applying a small amount of pressure, rub the foam parts together to get the surfaces completely smooth.
- 3). Cut a channel in the wings using a razor knife about 1/4 inch deep at the thickest point of the wing on both faces, using a straightedge to provide a good clean cut. Use a 2 mm screwdriver to remove the foam from the cut. Insert carbon rods into this channel spanning the entire length of the wing and glue them into place using super glue. Sprinkle a layer of baking soda onto the glue to strengthen it and remove the excess. The carbon fiber will provide additional support to the wing, creating a firmer structure. Glue carbon fiber supports into the fuselage of the airplane below the wing, into the rudder piece and into the aileron and elevator.
- 4). Build the aircraft body, following the manufacturer's directions. Use hot glue to attach the wings, tailpiece and rudder to the aircraft body. Go light on the glue, as any added weight detracts from the airplane's performance.
- 5). Attach the engine to your aircraft by mounting a plywood panel to the aircraft nose to act as a firewall between the engine and the aircraft body as well as to provide a solid mounting foundation for the motor. Attach the engine to the plywood piece, clamping it securely into place.
- 6). Install the servos into the aircraft body, using hot glue to secure them. The servos operate the rudder, elevator and aileron, so will have to be placed carefully to control the push-pull control system rods. The location of servo installation should be in the kit's directions.
- 7). Install the control system for your airplane. Most RC airplanes use a push-pull system for controlling the elevator, aileron and rudder of the aircraft. Run the rods of the push-pull system through the body of the aircraft and connect them to all three controlled parts. Connect the other end of the rods to the servos.
- 8). Install the speed controller and the radio receiver. Wire the receiver to the speed controller and the servos, and wire the speed controller to the engine.
- 9). Mount the battery onto the aircraft to provide power for the electrics and the motor.
