The origins of CA glue
CA glue, also known as “super glue”, has been used for decades in a variety of applications, including in RC modeling. The origins of CA glue can be traced back to the 1940s when Harry Coover, a chemist at Eastman Kodak, was conducting experiments to create a clear plastic for use in precision gun sights during World War II. However, he accidentally discovered a new adhesive that was incredibly strong, clear, and resistant to water and heat.
Initially, the new adhesive didn’t have any practical applications and was forgotten until the 1950s when Coover and his team revisited it and found that it was still just as effective after several years. The adhesive was eventually marketed for industrial purposes under the name “Super Glue” by the company Eastman Kodak in 1958.
The name “CA glue” or “cyanoacrylate glue” came later when the adhesive was further developed and refined to be used in medical and veterinary settings. Its ability to seal wounds and other injuries quickly and effectively made it a valuable tool in emergency situations.
Today, CA glue is widely available and is used for a variety of applications, including in RC modeling. Its quick-drying and strong adhesive properties make it an ideal choice for many modeling scenarios. To learn more about the benefits of using CA glue in RC modeling, continue reading the next section.
How CA glue works
CA glue, also known as cyanoacrylate adhesive, works by creating a chemical reaction when it comes into contact with water. The reaction causes the glue to harden and create a strong bond between two surfaces. This type of adhesive is known for its quick-drying and strong bonding properties, making it a popular choice for RC modelers.
The chemical structure of CA glue is what allows it to work so effectively. It is composed of molecules that have a carbon triple bond to a nitrogen molecule. When the glue is exposed to water, the water molecules react with the triple bond, causing it to break and create a strong bond between the glue and the surface it’s being applied to.
Here’s a breakdown of how CA glue works:
| Step 1: | CA glue is applied to the surface |
| Step 2: | The glue comes into contact with water molecules in the air or on the surface |
| Step 3: | The water molecules break the carbon triple bond in the glue |
| Step 4: | The broken bond creates a chemical reaction that hardens the glue and creates a strong bond between the two surfaces |
It’s important to note that the strength of the bond created by CA glue can vary depending on the surfaces being bonded and the conditions in which it’s applied. Additionally, the reaction caused by the glue can be accelerated by the presence of certain metals, such as copper and iron. It’s recommended to follow the manufacturer’s instructions and take proper safety precautions when working with CA glue.

Tips for using CA glue in specific RC modeling scenarios
Tips for using CA glue in specific RC modeling scenarios:
- Bonding small parts: In RC modeling, sometimes you need to bond small parts, like a circuit board or a servo motor. When bonding small parts, use a small amount of CA glue. It will help you to avoid glue overflow, which can damage the parts or components. Overusing glue can also make your model heavier, which can severely affect its performance. You can use super glue for bonding small parts as it has a low viscosity and can easily penetrate even the tiniest cracks and gaps.
- Repairing propellers: Broken or damaged propellers can be a headache for RC modelers. In such cases, CA glue can be a savior. Apply a small amount of glue to the broken area and press it gently. Hold it for a few minutes until the glue dries completely. As the glue dries quickly, you can get back to flying faster. While Krazy glue is also useful for propeller repair, you may want to know how much weight it can hold before applying it.
- Bonding landing gear: Landing gear is one of the most delicate and crucial parts of an RC model. CA glue is ideal for bonding landing gear, as it offers a strong and instant bond. However, before bonding, make sure that the surface is clean and free from any dirt, oil, or grease. You can use alcohol to clean the surface before applying the glue. Loctite super glue is also a reliable choice for bonding landing gear. It produces a durable bond that can withstand high stress and friction, so you don’t have to worry about damaging or losing the wheels.
- Gluing delicate parts: Sometimes, RC models feature delicate parts like canopies, cockpit glasses, or wingtips, which require extra care when gluing. For attaching delicate parts, use a gel-based CA glue, which has a higher viscosity and stays in place. It will help you to avoid glue overflow and unwanted bond. You can also use a slower-drying glue, which will give you enough time to adjust the position of the delicate part before it dries. Krazy glue is perfect for gluing delicate parts due to its high precision application formula. You can learn more about what Krazy glue is used for here.
Remember that CA glue is not suitable for all RC modeling scenarios, and sometimes, you may need to use other types of adhesives or materials. If you are unsure about using CA glue, consult with experienced modelers or a hobby shop expert for advice.
