How to Make a Lexan RC Car Body
Introduction
Radio-controlled (RC) cars are a popular hobby enjoyed by people of all ages. One of the most important parts of an RC car is its body, which protects the car’s internal components and gives it a unique look. Lexan is a lightweight, durable plastic that is often used to make RC car bodies. In this article, we will provide a step-by-step guide on how to make a Lexan RC car body.
Materials and Tools
Before you begin, you will need to gather the following materials and tools:
* Lexan sheet (0.040″ or 0.060″ thickness)
* Scissors
* Hobby knife
* Ruler
* Pencil or pen
* Masking tape
* Sandpaper (various grits)
* Primer
* Paint
* Clear coat
* Heat gun or hair dryer
* Rolling pin or round object
* Body posts or mounting hardware
Step 1: Design and Cut the Body
* Start by designing your body on paper or using a computer-aided design (CAD) program. Make sure to include all the necessary details, such as the wheelbase, width, and height.
* Once you have a design, transfer it to the Lexan sheet using a pencil or pen. Use a ruler to ensure accuracy.
* Cut out the body using scissors or a hobby knife. Be careful to follow the lines closely and avoid any jagged edges.
Step 2: Trim and Sand the Edges
* Use a hobby knife to trim any excess Lexan around the edges of the body. This will help to reduce weight and make the body more aerodynamic.
* Sand the edges of the body using sandpaper to smooth them out. Start with a coarse grit sandpaper and gradually move to a finer grit.
Step 3: Form the Body
* Heat the Lexan sheet using a heat gun or hair dryer. This will make the plastic more pliable and easier to form.
* Use a rolling pin or round object to form the body into the desired shape. Be careful not to overheat the plastic, as it can melt or warp.
* Allow the body to cool completely before moving on to the next step.
Step 4: Mount the Body
* Use body posts or mounting hardware to attach the body to the RC car chassis. Make sure the body is securely mounted and that it does not interfere with the car’s movement.
Step 5: Prime and Paint the Body
* Apply a thin coat of primer to the body to help the paint adhere. Allow the primer to dry completely.
* Paint the body using your desired colors. You can use spray paint, acrylic paint, or enamel paint. Allow the paint to dry completely.
Step 6: Apply a Clear Coat
* Apply a thin coat of clear coat to the body to protect the paint and give it a glossy finish. Allow the clear coat to dry completely.
Step 7: Finish and Install
* Once the clear coat is dry, the body is complete. You can now install it on your RC car and enjoy the fruits of your labor!
Tips and Tricks
* Use a sharp hobby knife to cut the Lexan sheet. A dull knife will tear the plastic and create rough edges.
* Sand the edges of the body thoroughly to prevent any sharp edges from catching on obstacles.
* Heat the Lexan sheet slowly and evenly to avoid overheating and warping.
* Use a variety of sandpaper grits to achieve a smooth finish on the body.
* Primer is essential for helping the paint adhere to the Lexan sheet.
* Use high-quality paint and clear coat to ensure a durable finish.
* Allow the body to dry completely between each step.
* Be patient and take your time. Making a Lexan RC car body is a rewarding experience that can be enjoyed by people of all skill levels.
