VTX

Introduction 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. What is SmartAudio? SmartAudio is a communication protocol developed by TBS (Team BlackSheep) that allows control of various aspects of video transmitters (VTX) via the flight controller. With SmartAudio, pilots can change the transmission power, frequency, and even disable the transmitter, all directly from the OSD. This offers increased flexibility and convenience, especially during races where conditions can change rapidly. Prerequisites for the Setup Before starting, make sure you have the necessary hardware and software: An FPV drone with a SmartAudio-compatible VTX. A flight controller that supports Betaflight or another compatible firmware. A computer with Betaflight Configurator installed. A USB cable to connect the flight controller to the computer. Connecting the VTX to the Flight Controller The first step is to properly connect the VTX to the flight controller. Here are the general steps to make this…

If you are a pilot who is exploring new FPV system or a person who wants to enter this world,this article is for you! You will be able to find the different technologies with which you can get to arm your drone and a very simple benchmarking based on my experience, since I have had the opportunity to try them all for more than 4 years. In this way you can have first-hand information based on the personal experience of a pilot and understanding what you could use each system and get the best out of it. About the FPV Systems  Let’s start with something simple, now we can find two great FPV systems in the market: Analog fpv system and digital fpv system. Analog fpv system is the classic video that has been used since the beginning in FPV drones. This technology has different characteristics and different uses and we can highlight within them the versatility that has to be implemented in all types of drones, also in order to reach large distances and better penetrations in environments. Approximately three years ago digital video technology for FPV drones initially had the technology developed by DJI which evolved over time…

Introduction: This guide examines the performance of FPV VTX units under non-standard voltage conditions. It discusses challenges arising from flight controllers lacking a stable 10-volt power supply, affecting VTX operation. It highlights how lower voltage supply impacts VTX power output and emphasizes the importance of voltage matching for reliable video transmission in FPV setups. FPV VTX performance under non-standard voltage. Voltage compatibility for FPV VTX. Lower voltage impact on VTX power. Performance implications, including signal loss. Importance of voltage matching for reliable transmission. Consideration of voltage compatibility when selecting components. What you need： Freestyle Recommended: Racing Recommended: Video Overview Now we'll discuss whether the FPV VTX (Video Transmitter) can operate effectively under non-standard voltage conditions. Voltage Compatibility for FPV VTX Our flight controllers come in both HD and analog versions. However, the analog version lacks a stable 10-volt power supply. This poses a challenge when using VTX units that require a 10-volt input to function optimally. Effects of Lower Voltage In situations where the flight controller can only provide 5 volts, the VTX can still operate. However, due to the lower voltage supply, the VTX may not achieve its rated power output. For instance, a VTX rated for 500 watts…

Introduction With the price increases that have occurred in recent years and continue to persist, building an affordable drone has become increasingly challenging, but not impossible. In this guide, I will list some websites where you can purchase budget-friendly components. Additionally, I will provide two examples of cost-effective builds, one for freestyle and one for cinematic drones. It's important to note that when constructing a drone, it's essential to have a clear understanding of the frame on which you'll be mounting the electronics. This helps you determine the available hole patterns for mounting and select components that are compatible with these measurements. Furthermore, you should possess the skills for soldering/desoldering, know how to connect various components, and be capable of configuring the system once it's assembled. In this brief article, however, as mentioned earlier, I will solely focus on listing the components for two budget-friendly builds. Websites And Economic Fpv Drone Components Let's start by listing the websites where you can purchase materials for our budget-friendly build. Unfortunately, there are fewer sites with excellent prices, but fortunately, there are still some available. For materials for a budget build, you should consider purchasing from the following sites: Mepsking.com: This site offers…

What is Analog and Digital FPV VTX Systems? There are two categories of FPV systems: analog and digital. The signal is what distinguishes digital from analog. A digital system first encodes the wave as ones and zeros before transferring it, whereas an analog system continually changes the wave's amplitude or frequency. The most traditional, least expensive, and widely used technology is analog, which operates at 5.8GHz, 2.4GHz, and 1.2/1.3GHz. On the other hand, digital technology is more recent and is becoming more and more popular. It provides better image quality. Digital is anticipated to become widely used soon. Features of digital FPV system There are now three 5.8GHz digital FPV systems available for FPV drones; however, since they are all proprietary systems, none of them are cross-compatible. Consequently, unless you have the funds for multiple systems, you must decide which one to choose. For FPV drones, there are now three digital FPV systems available: HDZero, Walksnail, and DJI. Digital FPV hardware cannot be used with analog equipment. Additionally incompatible with other digital FPV systems are cameras and VTXs made for a particular digital FPV system.The drone's video transmitter is the part that wirelessly transfers video from our FPV cameras to…
