Hey there! When you want to learn more about FPV drones and build your own drone, then you must understand the parts of an FPV drone. There are three main categories of parts: the flight system, the power system, and the FPV system. The flight system includes motors, propellers, electronic speed controllers (ESCs), a flight controller, and a radio receiver. The power system consists of a battery and a power distribution board. This guide will explain in detail what makes up an FPV drone and exactly what the parts are. Without a doubt, beginners can absolutely build FPV drones even without any experience! If you want to build one and are unsure about how to choose from so many parts for FPV drone, you'll understand it all after watching this video: How to Choose FPV Drone Parts. When selecting a frame, ensure the mounting holes match those of the flight controller. Pay attention to the KV value of the motor and choose the appropriate power according to your needs. When choosing an Electronic Speed Controller (ESC), make sure its maximum current rating is higher than that of the motor. Select the appropriate flight controller (FC) and video transmission equipment (VTX)…

Choosing the right digital FPV system can be overwhelming. With the release of the DJI O4 Air Unit, many pilots are asking: Is it compatible with my drone? Is it better than O3? Is the installation process complicated? Without a clear understanding, you might waste money on incompatible gear or struggle with poor installation, leading to latency issues, weak signals, or even permanent damage to your components. This complete guide walks you through everything you need to know before buying the DJI O4, including key upgrades, compatibility checks, wiring diagrams, setup steps, and pro tips. Whether you're a beginner or pro, this article ensures you unlock the full potential of DJI's latest FPV system.

Racing drones and FPV (First Person View) drones are increasingly popular among flight enthusiasts. For these pilots, having complete control over their video system is crucial. SmartAudio is a technology that allows you to adjust the video transmitter (VTX) settings directly from the On-Screen Display (OSD). This detailed guide explains how to set up SmartAudio to control the VTX from the OSD. FPV VTX: Get to Know the Installation and Settings of VTX Smart Audio The FPV VTX (Video Transmitter) plays a crucial role in FPV drones, transmitting video signals from the drone’s camera to the goggles worn by the pilot. The power output on an FPV VTX can vary widely, offering levels such as 25mW, 200mW, 600mW, and even up to 1W. This variability allows pilots to adapt to different flight environments: Low power output (25mW) is ideal for indoor flights or short distances. Higher power output (200mW–1W) is necessary for outdoor flights or longer ranges to maintain a strong and stable video signal. However, manually changing the VTX power output can be time-consuming and inconvenient, especially when transitioning between different flight locations. The introduction of VTX Smart Audio revolutionizes this process by enabling pilots to adjust the power output directly through their flight…
