Yes, it is possible to build your own helicopter if you have the necessary knowledge and experience. However, this is not a task for beginners and requires a considerable amount of time, effort, and resources. It is essential to understand aviation regulations and safety standards, as well as having access to high-quality parts and materials.

If you are interested in building your own helicopter, there are several resources available online, including websites such as and, which offer kits and instructions on how to build your own helicopter. However, it is recommended that you also seek the assistance of professionals and experts in the field to ensure that the final product is safe and fully functional.

Gathering Materials

Now that you’ve completed your research and planning, it’s time to gather the necessary materials and components to build your RC helicopter. Here’s what you need to know:

Materials You’ll Need

  • Frame: The body of the helicopter where all the other parts will be attached
  • Rotors: The blades that create lift and enable the helicopter to fly
  • Electronic speed controllers (ESC): Control the speed of the motor by regulating the amount of power sent to it
  • Flight Controller: Acts as the brain of the helicopter, controlling its movements in the air
  • LiPo Battery: Provides the power needed to run the helicopter
  • Brushless Motor: A type of motor that uses an electronic controller instead of a brush to power it

Where to Find Materials

  • Online stores like HobbyKing, Amazon, and Banggood
  • Local hobby stores in your area
  • Aircraft salvage yards that may have helicopter parts

Interesting fact: Did you know that the first RC helicopter was invented in the 1960s and was powered by a gasoline engine? Thankfully, technology has come a long way since then, and today we have much more efficient and safer options available for building RC helicopters from scratch. With the right materials and a little bit of patience and persistence, anyone can build their own RC helicopter and experience the thrill of flying it!


With all the materials in hand, it’s time to start assembling your RC helicopter. Here are some things to keep in mind:

The Step-by-Step Process

  1. Attach the motors to the frame
  2. Wire the electronics
  3. Install the rotor blades
  4. Calibrate the flight controller
  5. Test the helicopter to ensure everything is working properly

Tips and Tricks

  • Take your time and be patient. Rushing through the assembly process can result in mistakes and frustration.
  • Ensure that all components are securely fastened to the frame to prevent any accidents.
  • Double-check that all wiring is correct and secure.
  • Balance the rotor blades to ensure a smooth and stable flight.
  • Refer to online tutorials and videos for guidance if you are unsure about any step in the process.

Product Recommendation: if you want to make the process even easier, you can consider buying an RC helicopter kit that comes with all the necessary materials and an instruction manual. A popular choice is the Blade 230 S V2 RTF Flybarless Electric Collective Pitch Micro Helicopter, which comes with a fully-assembled helicopter, a controller, a battery, and a charger.

How long does it take to learn to fly an RC helicopter?

It can take anywhere from a few hours to several months of practice to learn to fly an RC helicopter proficiently. Factors such as prior experience with remote control vehicles, dedication to practice, and the complexity of the helicopter model all play a role in how quickly one can learn.

For those looking to get started with RC flying, there are many resources available online including tutorials, forums, and instructional videos from websites like RC Groups and RC Universe. Additionally, some RC helicopter manufacturers offer beginner-friendly models with features like stability assistance and simplified controls to help new pilots learn more quickly.

Testing and Calibration

Once you have assembled your RC helicopter, it’s crucial to test and calibrate it before flying. Here are some things to consider:

Testing Your RC Helicopter

  1. Perform a ground test by slowly increasing the throttle and ensuring that the motors spin in the correct direction.
  2. Perform a hover test to ensure that the helicopter is able to stay stable in the air.
  3. Perform a flight test to check that the helicopter is responsive to the controller.

Calibrating Your RC Helicopter

  1. Balance the rotor blades to ensure a smooth and stable flight.
  2. Adjust the sensitivity of the controller to your preference.
  3. Ensure that the center of gravity is optimal for stable flight.

Product Recommendation: A popular choice for calibration that can help make sure that the helicopter is in good shape is “The Perfect Balancer”. This tool can help balance the blades of the helicopter, which makes sure the helicopter flies straight and is not vibrators. The tool is perfect for calibration your helicopter if you want the best results.

Why is my RC helicopter not lifting?

There are a few reasons why your RC helicopter may not be lifting, including:

  • The batteries may be dead or low on power, causing the helicopter to not have enough power to lift off the ground
  • The propellers may be damaged or not spinning properly
  • The weight of the helicopter may be too heavy for the motor to lift
  • The helicopter may not be balanced properly, causing it to tip and not lift off

Check your batteries, propellers, weight, and balance to troubleshoot why your RC helicopter isn’t lifting. Additionally, you may want to check with the manufacturer or website where you purchased the helicopter for specific troubleshooting tips or product support.

Troubleshooting and Maintenance

Like any mechanical device, RC helicopters can sometimes malfunction or break down. Here are some common issues and solutions to consider, as well as some tips for maintaining your RC helicopter:

Common Issues and Solutions

  • The helicopter flies erratically or suddenly drops – this may be due to a problem with the gyro or incorrect pitch settings, which can be fixed with calibration.
  • The blades are chipped or damaged – replace the blades immediately, as damaged blades can cause instability and potential for a crash.
  • The motors are overheating – this could mean that they are working too hard or that there is a problem with the cooling system. Try reducing the workload or adjusting the air intake, respectively.

Maintenance Tips

  • Store your RC helicopter in a dry and cool place, away from dust and moisture.
  • Regularly clean the blades and motors, as dust and debris can accumulate and cause damage over time.
  • Check the batteries regularly and replace them as soon as you notice a decrease in performance.

Product Recommendation: A good quality screwdriver set like the “Craftsman Ultimate Screwdriver Bit Set” can come in handy when maintaining your RC helicopter. It comes with 208 different screw heads, including many specialty bits that are perfect for working with small screws found in RC helicopters.

What causes helicopter malfunction?

There are several factors that can contribute to a helicopter malfunction, including:

  • Pilot error
  • Equipment failure
  • Weather conditions
  • Maintenance issues
  • Structural damage

Helicopter malfunctions can lead to dangerous situations, including crashes and accidents. It’s essential to understand the causes and take necessary precautions to avoid them.
