MakerBazar - How to Build an RC Plane from Scratch?

Building your own RC airplane from scratch is an exciting and rewarding experience for hobbyists and enthusiasts. By constructing your RC airplane, you not only gain a deeper understanding of its mechanics but also have the freedom to customize it to your preferences. In this comprehensive guide, we will walk you through the step-by-step process of building your own RC plane, from planning and gathering materials to the final test flight.

Materials Used in RC Airplane Step by Step: - How to build an RC Plane
  1. Airframe materials (balsa wood, foam, carbon fiber)
  2. Adhesives (epoxy, CA glue)
  3. Covering material (heat-shrink covering or adhesive-backed film)
  4. Control linkages (pushrods, control horns)
  5. Hardware (screws, bolts, hinges)
  6. Power system components (motor, propeller, ESC)
  7. Radio system (transmitter, receiver, servos)
  8. Battery
  9. Wiring
  10. Tools (hobby knife, scissors, sandpaper, soldering iron)
  11. Measuring instruments (ruler, calipers)
  12. Heat gun or iron (for covering application)
  13. Weights (if needed for balance)
  14. Paint (optional for customization)
  15. Velcro or straps (for securing components)
  16. Servo extensions or Y-connectors (for wiring setup)

1. Planning and Design

  • Determine the Type: Start by deciding on the type of RC plane you want to build, such as a trainer, sport plane, or scale model. Consider your skill level, flying preferences, and available resources. Research various designs and select a model that suits your needs.
  • Acquire Plans or Kits: Gather plans or purchase a kit for your chosen aircraft model. Plans provide detailed instructions and templates for cutting and assembling the various components. Kits usually include pre-cut parts, reducing the time and effort required for construction.
  • Study the Plans: Thoroughly examine the plans or kit instructions to familiarize yourself with the assembly process. Understand the sequence of construction and the required tools and materials. Take note of any special considerations or modifications mentioned in the instructions.


2. Gathering Materials and Tools

  • Materials: Collect all the necessary materials as per the plans or kit instructions. This includes the airframe materials (balsa wood, foam, or carbon fiber), adhesives, covering material, control linkages, and hardware such as screws, bolts, and hinges. Ensure you have sufficient quantities and quality materials for the construction.
  • Tools: Equip yourself with the necessary tools for building the RC airplane. These may include cutting tools (hobby knife, saw, or scissors), measuring instruments (ruler, calipers), sandpaper, soldering iron, drill, and a heat gun. Organize your tools for easy access during the construction process.

3.  Airframe Construction

  • Cutting and Shaping: Start by cutting out the various components from the provided templates or pre-cut parts. Use the appropriate cutting tools and take your time to ensure accurate cuts. Shape the components as needed, sanding them down for smooth edges and surfaces.
  • Fuselage Assembly: Follow the plans or kit instructions to assemble the fuselage. Join the fuselage sides and bulkheads using suitable adhesives, ensuring proper alignment. Reinforce critical areas with additional supports as specified in the instructions.
  • Wing and Tail Construction: Build the wings and tail surfaces separately. Assemble the wing ribs, spars, and leading and trailing edges according to the plans. Use suitable adhesives to join the components securely. Similarly, construct the tail surfaces, such as the horizontal stabilizer and vertical fin.
  • Landing Gear and Control Surfaces: Install the landing gear as per the instructions, ensuring it is securely attached to the fuselage. Build and attach the control surfaces, such as ailerons, elevator, and rudder, using hinges and control horns. Ensure smooth and unrestricted movement of the control surfaces.

4.  Installation of Power System and Electronics

  • Power System: Mount the motor on the firewall of the fuselage using a motor mount. Install the propeller on the motor shaft, ensuring it is balanced and securely fastened. Connect the motor to an electronic speed controller (ESC) and attach the ESC to the receiver.
  • Radio System: Install the receiver in a suitable location within the fuselage, ensuring it is securely mounted. Connect the servos to their respective control surfaces, making sure the servo arms are properly aligned with the control horns. Bind the receiver to your transmitter and perform a range check to ensure proper communication between the transmitter and receiver.
  • Battery and Wiring: Select an appropriate battery for your RC airplane and mount it securely within the fuselage. Connect the battery to the ESC, ensuring the polarity is correct. Organize the wiring neatly and secure it in place to prevent interference or damage during flight.

5. Finishing Touches and Testing

  • Covering: Cover the airframe with heat-shrink covering material or adhesive-backed film for a smooth and polished appearance. Carefully apply the covering, ensuring there are no wrinkles or bubbles. Use a heat gun or iron to shrink the covering and create a tight, wrinkle-free surface.
  • Balance and Control Setup: Determine the center of gravity (CG) for your RC airplane as specified in the plans. Adjust the battery position or add weights to achieve the proper balance. Set up the control surfaces to ensure they respond accurately to the transmitter inputs, adjusting servo throws and control linkage as needed.
  • Pre-Flight Checks: Perform a thorough inspection of the completed RC airplane, checking for any loose connections, damaged components, or potential issues. Double-check the control surface movements, motor responsiveness, and radio system functionality. Ensure all components are securely fastened and that the aircraft is structurally sound.
  • Test Flight: Choose a suitable flying location, preferably an open area away from obstacles or people. Perform a test flight with caution, gradually increasing the throttle and assessing the airplane's stability and control response. Make any necessary trim adjustments during the flight to achieve a balanced and smooth flight performance.


Building your own RC plane is a gratifying endeavor that allows you to unleash your creativity and acquire valuable knowledge about aeronautics and electronics. By following this step-by-step guide, you can embark on the journey of constructing your own RC plane. Remember to exercise patience, attention to detail, and safety throughout the process. Enjoy the process of building and experience the thrill of flying a model aircraft that you've crafted with your own hands. Happy building and happy flying!
