Building Your First RC Plane: The Comprehensive Guide to Using Foamboard

The world of remote-controlled (RC) aircraft is an exciting space, brimming with endless possibilities for enthusiasts and novices alike. Among the array of materials utilised in the construction of RC planes, foamboard stands out as a popular choice. This guide will take you through the nuances of using foamboard in building your first RC plane.

Introduction

From thrill-seekers to innovators, the RC plane fraternity is a diverse one. The allure of constructing and navigating these miniature aircraft has drawn countless individuals into this intriguing sphere. Among the assortment of materials available for building RC planes, foamboard is an esteemed favourite. Renowned for its affordability, accessibility, ease of use, and considerable durability, foamboard presents a fantastic starting point for beginners.

The Appeal of Foamboard

Foamboard is a lightweight yet sturdy material, comprising a foam core sandwiched between two layers of thin, rigid paper. Its unique construction offers a blend of flexibility and strength that makes it particularly suitable for building RC planes. Furthermore, its affordability and easy availability in stores like Dollar Tree or Dollar General add to its appeal.

The Essential Components

Before we delve into the specifics of building an RC plane, let's first familiarise ourselves with the essential components involved in this endeavour. From the transmitter and receiver to the battery and the electronic speed controller (ESC), understanding the function of these parts forms the bedrock of your RC plane building journey.

Transmitter and Receiver

These two components form the communication bridge between you and your RC plane. The transmitter sends signals that are picked up by the receiver mounted on the plane, controlling its movements.

Battery

The battery serves as the power source for your RC plane. It supplies the necessary energy to the motor, propelling the plane.

Electronic Speed Controller (ESC)

The ESC regulates the speed of the plane's motor, translating the signals received from the transmitter into corresponding motor speeds.

Brushless Motor

This is the powerhouse of your RC plane. The brushless motor turns the electrical energy from the battery into mechanical energy, spinning the propellers and providing the thrust needed for flight.

Servos

Servos are the 'muscles' of your RC plane, controlling the movement of the control surfaces (e.g., ailerons, elevators, and rudders) that steer the plane.

Propellers

Propellers are essential for flight. They spin at high speeds, creating a difference in air pressure that lifts the plane off the ground.

Connectors, Wires, and Other Accessories

These include various connectors (like XT60 battery connectors and 2mm gold bullet connectors), wires, servo extenders and splitters, heat shrink tubing, control horns, and more. These components are crucial for the assembly and operation of your RC plane.

Selecting the Right Foamboard

Not all foamboards are created equal. Different types of foamboard come with their unique features and are suited for different purposes. For building an RC plane, you'll want to use a foamboard that's lightweight yet durable, easy to work with, and, ideally, water-resistant.

Depron Foam

Depron is a popular choice among RC plane builders. This lightweight, closed-cell extruded polystyrene foam is easy to cut, shape, and glue. It's also waterproof, making it ideal for outdoor use.

BlueCor / PolyPro Foam

BlueCor, also known as PolyPro, is another excellent foamboard option. It's less stiff than Depron but shares similar water-resistant properties.

Readi-Board Foam

Readi-Board foam is an economical choice for beginners. It's easy to cut and shape, and the paper backing adds rigidity. However, it may begin to delaminate over time, especially in humid environments.

Fli-Power Value XPS RC Model Foam

Fli-Power Value XPS foam is a newer entry in the market, boasting weatherproof properties and flexibility. It's less rigid than Depron but more flexible, making it a good choice for complex designs.

The Building Process

Now that we've covered the basics, let's dive into the actual process of building your first foamboard RC plane. This process involves designing your plane, cutting out the foamboard pieces, assembling them, and installing the electronics.

Designing Your Plane

Before you start cutting and gluing, you'll need a design for your plane. This design will dictate the shape, size, and configuration of your plane. You could opt for a simple trainer-style plane for your first build, which is easier to construct and fly.

Cutting Out the Foamboard Pieces

Once you have a design, you'll need to transfer it onto your foamboard and cut out the pieces. This step will require a sharp hobby knife and a steady hand. Always remember to practice safety when using sharp tools.

Assembling the Plane

With your foamboard pieces cut out, it's time to assemble your plane. This process involves gluing the pieces together in the right configuration, forming the fuselage, wings, tail, and other parts of your plane.

Installing the Electronics

The final step in building your foamboard RC plane is installing the electronics. This includes mounting the motor, installing the servos, connecting the ESC, and setting up the receiver. It's vital to ensure that all parts are correctly connected and securely attached.

Flying Your Foamboard RC Plane

With your foamboard RC plane assembled and the electronics installed, you're ready to take to the skies. Always remember to check the controls before each flight and maintain a safe distance from people or structures.

Building your first foamboard RC plane can be a thrilling and rewarding experience. With time and practice, you can refine your building skills, experiment with different designs, and explore the exciting world of RC flying. Happy flying!
