1 What is an FPV Drone？

An FPV drone, or First Person View drone, is a type of drone designed for immersive flying. Unlike traditional drones like the DJI Mavic, which are equipped with automated features such as altitude hold and self-leveling, FPV drones require full manual control. This means the pilot manages every aspect of flight, including altitude, speed, and direction, giving a more hands-on and responsive flying experience. FPV drones are flown using a set of goggles that display a live video feed from the drone’s onboard camera, allowing the pilot to see from the drone’s perspective, making it feel like they are flying in the sky themselves.

4 The Parts Lists and Additional Tools

4.1 The Parts List

• Frame – The frame is the foundation of your FPV drone. For a 5-inch freestyle drone, you’ll need a frame that supports 5-inch propellers. Choose one that is durable and can handle crashes, as freestyle flying can be tough on your drone.
• Video System – Your video system is essential for a clear FPV experience. It includes a camera and a video transmitter (VTx). Popular options include systems like DJI, Walksnail, HDZero, or Analog. Pick one that matches your existing gear and flying style.
• Batteries – Batteries power your drone, and selecting the right type is crucial. Most 5-inch builds use 4S (4-cell) or 6S (6-cell) batteries, depending on the motors and ESC you choose.
• Motors – Motors drive your propellers and affect how your drone flies. Look for motors with the right size and kV rating to suit your build and flight goals.
• Electronic Speed Controller (ESC) – The ESC regulates the power going to your motors. Make sure it’s compatible with your motors and battery setup. A 4-in-1 ESC is a popular choice for cleaner wiring.
• Flight Controller (FC) – The flight controller is the brain of your drone, processing all the commands and sensor data. Ensure it’s compatible with your ESC and has the features you need for your flying style.
• Radio Receiver – The receiver connects your transmitter to the drone. Popular options include ELRS, Crossfire, or Tracer. Choose one that pairs with your transmitter for seamless control.
• Video Antenna – A quality video antenna improves your video signal strength and range. Some video systems include antennas, but analog setups often require separate ones for better performance.
• Propellers – Propellers are vital for flight. Choose ones designed for your frame and motor setup. It’s always a good idea to have spares on hand.
• Other Essentials – Don’t forget items like a battery charger and power supply to keep your batteries ready for action. If you already own a charger for smaller drones, check its compatibility with your new batteries.

5. Steps of Building FPV Drone

5.1 Frame Assembly

Before assembling the frame, consider sanding the edges of the carbon fiber parts to prevent them from cutting wires or straps during crashes. Washing the parts with soapy water can also remove conductive carbon dust, but ensure everything is completely dry before proceeding.

To assemble, align the arms and arm lock with the bottom front plate. Secure the rear bottom plate with screws and push nuts over the arms. Finally, attach the aluminum standoffs, ensuring the longer standoffs are at the front. Tighten everything carefully, and your frame is ready for the next steps!

5.2 Mounting Motors

Start by attaching the motors to the arms using screws, and consider applying a small amount of threadlock (like blue Loctite) to prevent them from loosening due to vibrations. Pull the motor wires tight and secure them to the arms with zip ties for a clean look. When soldering, tin both the motor wires and ESC pads first, then carefully solder each wire to its corresponding pad, one at a time. Use just enough solder to ensure a strong connection, and trim any excess wire neatly. Once done, wrap the wires with tape for added protection.

5.3 Soldering the Electronics

Soldering the electronics is a critical step that requires precision and patience. To make it easier, print out the flight controller’s pinout diagram and plan your connections carefully. You’ll be working with three main components: the camera, video transmitter (VTx), and receiver. Each system usually has three key wires—5V for power, Ground, and Signal.

Start by tinning both the wires and the flight controller pads with a small amount of solder. Carefully solder each wire to its corresponding pad on the flight controller, ensuring the connections are solid and not bridged. Double-check the diagram to avoid mistakes. Secure the wires neatly with tape or zip ties to prevent damage or interference. Taking your time here will save you trouble later and ensure your drone operates smoothly.

5.4 Soldering the ESC to the Motors and Testing

If you’re using a 4-in-1 ESC, connect the three motor wires from each motor to the corresponding pads on one side of the ESC. The order doesn’t matter, as motor direction can be adjusted later. If you have individual ESCs, solder the three motor wires to one side of each ESC, and connect the two power wires and signal wire from the ESC to the flight controller.

Before plugging in a LiPo battery, check for electrical shorts using a multimeter in continuity mode. Test the positive and negative terminals of the XT60 connector. If there’s a continuous beep, troubleshoot the short before proceeding. A single beep followed by silence is normal due to capacitors charging.

For motor testing, leave the propellers off for safety. Connect the drone to Betaflight Configurator and use the Motors tab to spin each motor individually. Verify that each motor spins in the correct direction and matches its assigned position in the diagram (e.g., motor 1 is rear-right). Adjust wiring or motor direction as needed to ensure proper function.

5.5 Binding the Receiver

To bind the receiver, first, refer to your flight controller’s documentation for wiring instructions. Solder the four receiver wires (power, ground, signal, and telemetry, if needed) to the correct pads, and bridge any required pads to specify the receiver type. Plug the receiver into the flight controller.

To bind, turn on your radio and set it to bind mode. Power the drone with a LiPo battery, and the receiver should enter bind mode automatically. Once the radio indicates a successful bind (often with a solid green light), it may prompt a firmware update for the receiver—allow it to complete. After binding, unplug the receiver or secure it, and continue with the rest of the build. Avoid attaching the antenna yet to prevent damage.

5.6 Finishing Off

To finalize your build, secure the flight controller using nylon nuts. Tighten them gently by hand until they just touch the rubber grommets—over-tightening can compress the grommets and reduce their ability to dampen vibrations.

When installing the propellers, ensure they match the correct motor rotation: CW (clockwise) or CCW (counter-clockwise). Incorrectly installed propellers can cause the drone to flip or fail to take off. Double-check everything before your first flight, and your FPV drone is ready to go!

5.7 Setting Up Betaflight

Congratulations on completing your FPV drone hardware setup! However, your drone isn’t ready to fly just yet—you’ll need to configure the flight controller and ESCs using Betaflight. This step is essential and can be quite detailed, so take your time to learn the process thoroughly. Proper setup ensures stable flight, optimal performance, and safety during your maiden flight. Follow the Betaflight Configurator instructions carefully, and don’t rush through this critical step.
