Introduction: FPV desync happens when an ESC loses sync with its motor, causing the motor to stall or cut out mid-flight. To fix it: inspect your hardware, add a low-ESR capacitor, and tune BLHeli & Betaflight settings like rampup power, demag compensation, and motor idle to stabilize your system. What is Desync Issue? FPV desync (ESC desync) occurs when the Electronic Speed Controller (ESC) fails to keep up with the motor’s commutation timing. Once the ESC loses track of the motor’s position, the motor stalls and your drone can violently spin (death roll) and crash. Typical signs of FPV motor desync: Sudden flip or roll mid-air (usually just one motor stops) Stuttering noise from one motor Blackbox logs showing a motor command hitting 100% while thrust drops For example： Sometimes in flying, when you push the throttle and do some action, one of your motors will stop spinning, and then most likely you will crash. When reviewing the black box data, you may find the control signal curve for the motor increases rapidly to 100%. However, the gyroscope records indicate that the aircraft's attitude did not respond as expected to this motor speed increase; instead, it suddenly dropped to zero. Pro…

Introduction: DSHOT300 and DSHOT600 are digital ESC protocols used in FPV drones, differing primarily in signal rates. The choice between them depends on the flight controller type, with DSHOT300 suited for AIO controllers and DSHOT600 for F7 or F405-based controllers. Understanding these differences allows pilots to optimize their drone's performance by selecting the appropriate protocol. Definition: DSHOT300 and DSHOT600 are digital ESC protocols used in FPV drones to regulate throttle communication between flight controller and ESCs. Selection Criteria: Choose DSHOT300 for AIO flight controllers (F411 chip) and DSHOT600 for F7 or F405-based controllers. Key Difference: DSHOT600 offers higher throttle signal rate compared to DSHOT300, potentially enhancing drone performance. Optimizing Performance: Selecting the appropriate protocol ensures efficient communication, resulting in smoother flight and improved responsiveness. What you need： Freestyle Recommended: Racing Recommended: Video Overview Now we'll explore the differences between DSHOT300 and DSHOT600 and their significance in ESC protocol settings. What is DShot？ DShot is a digital ESC protocol for communicating throttle (and some commands) between your FC ↓ ESC. It differs from all other ESC protocols in that it is a digital signal. It offers enhanced performance and dependability, which is a positive step for ESC communication. You can give…

ESC faults are one of the most common issues faced by FPV drone pilots. ESCs are common areas of fault, often receiving the most abuse and continued strain of any electronic in the RC object. In this guide, we will discuss common ESC faults and ESC troubleshooting, including ESC burnout, desync, and firmware corruption. For those looking to better understand ESCs and how to select the right one for their FPV drone, check out this comprehensive guide on How to Choose the drone ESC. Fault 1: Understanding ESC Burnout and Prevention Tips This is by far the most common issue experienced with ESCs. Most of the time ESCs are bulletproof and connected to the FC, which allows for minimal tampering on the firmware side of things, allowing for low anomalies in the typical use cases. Unfortunately, they are not indestructible and thus large crashes, excessive stress or overvoltage may occur. This is physical damage to the ESC and is unfortunately very rarely fixable and when it is, it requires micro soldering skills to replace the damaged component, writing it off as its never worth it unless the part is discontinued and essential. Some physical cues of this problem would be: Physical chips or cracks in the board. Black soot near pads and components indicating a burnt board. Missing components and empty micro pads. Other forms of internal damage that may not be visible. There are currently no real fixes to this issue and if you rule out…

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…
