If you\u2019re here reading this, then something inspired you to do a little research into FPV multirotors as an FPV Beginner. \u00a0It can be a little intimidating when you are first starting out, but stick with it, the rewards far outweigh the challenges. \u00a0This series of articles is here to help you navigate your way through those challenges, and give you a good deal of insight into what you need to know to proceed. \u00a0While not all encompassing, you will have a good knowledge base with which to get started as an FPV Beginner.<\/span>[vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n <\/p>\n FPV or First Person View is the most unique experience of interacting with your aircraft through a level of immersion that is unparalleled by anything short of virtual reality. \u00a0In its most basic form, it takes you, the pilot, and transfers your visual consciousness into the body of a fast, agile, and precise flying machine. \u00a0It gives you a whole new and awe inspiring view of the world around you that only those who fly FPV get to experience. \u00a0There are really about three different schools of FPV multirotor flying; racing, freestyle, and aerial photography. \u00a0There\u2019s nothing saying you can\u2019t do more than one of these, or all three! \u00a0They each have their exciting aspects and there\u2019s a community out there to help support you through your journey.<\/span>[\/vc_column_text][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n Freestyle flying is all about your environment, your multirotor, and the interaction between the two. \u00a0It might be finding that new gap that your multirotor barely fits through, dodging ghost branches as you dance through your local park, finding cool new locations in which to explore, or finally learning that new trick that you saw on someone\u2019s flight video. \u00a0Freestyle is a form of expression in flight, more focused on acrobatics and exploring your environment. \u00a0Freestyle also has the added benefit of helping to prepare you for racing by pushing the limits of your multicopter through learning control. As an FPV Beginner, this is most likely where you will start in your journey!<\/span>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n FPV racing consists of flying either solo, or with a group of other pilots, through a series of obstacles, flags, and gates. \u00a0As with all racing, the goal is to get first place, either by beating all the other pilots to the finish line or getting the best time on the track. \u00a0While this may sound simple at first, most tracks will not only push the limit in terms of speed, but will also test your ability to maneuver your multirotor through all aspects of control. \u00a0Many races come down to who has the fastest reflexes and can find the best line in the track. \u00a0<\/span>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n Aerial photography is just that, viewing and recording whatever your chosen subject matter is from the air. \u00a0This is a great way to explore the world around you, and gives you a unique experience of taking your photography literally to a whole new level. \u00a0Aerial photography also has many practical uses, such as showing unique views of real estate, area mapping, or even filming movies!<\/span>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][ultimate_spacer height=”25″][vc_separator el_width=”20″][ultimate_spacer

these work both independently from one another and can work together to create more complex movement. \u00a0Let\u2019s start with an exercise to show each of these controls. \u00a0Hold your hand out in front of you palm down. \u00a0Rock your hand from side to side, that is your roll. \u00a0Now, tip your hand forward, then backward, that would be pitch. \u00a0Keeping your hand palm down, turn your hand left then right, that\u2019s an example of yaw. \u00a0Last, again, keep your palm face down, and lift your hand higher in the air then bring it back down, there is your thrust. \u00a0Now, when you start to combine roll with thrust, your multirotor will shift either left or right. \u00a0When you pitch forward the multirotor will start to move forward, and when you pitch back, it will move backward. \u00a0Yaw is generally used to change your heading, or the direction your multirotor is facing. \u00a0The more thrust you provide the faster the multirotor will gain altitude, and the roll and pitch effectively change what direction is truly up.\u00a0<\/span>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n When you first get into the hobby as an FPV Beginner, there is that little thing in the back of your mind that we like to call \u201cinstant gratification\u201d. \u00a0While there is no shame in buying a pre-built multirotor, and there are some great builders out there that will be more than happy to provide that for you, a word of caution; you will crash your multirotor\u2026. many, many times. \u00a0There are times where a part will not survive your crash, or a wire will get jarred loose, and unless you are fantastic with electronics, you may not know how to conduct repairs. \u00a0By going through the steps to build your first multirotor as an FPV Beginner, you will understand how the parts work in conjunction with one another, as well as how to fix anything that might be broken. \u00a0Plus, there is nothing as satisfying as building something that once complete, can take to the skies! \u00a0<\/span><\/p>\n Note: There are a few skills necessary to properly build a multirotor, <\/span>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][ultimate_spacer height=”25″][vc_separator el_width=”20″][ultimate_spacer

down into three distinct categories, the flight system, the power system, and the FPV system. \u00a0The flight system consists of motors, propellers, electronic speed controllers (ESC\u2019s), flight controller, and the radio receiver. \u00a0The power system consists of the battery and the power distribution board. \u00a0The FPV system contains the flight camera, the video transmitter (VTx), and the antenna. \u00a0While multirotors can definitely fly without the FPV system, and many pilots out there definitely enjoy the experience, adding the FPV system adds in that level of immersion that makes the experience that much more fulfilling. \u00a0All your components are mounted on your multirotor frame.<\/span>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n Frames are the backbone, the skeleton of your multirotor. \u00a0This is what all your components will mount to, and will ultimately dictate what the multirotor will look like. \u00a0There are hundreds of frame designs out there, and many pilots create their own custom frames that fit their individual flying styles. \u00a0Frames are measured in millimeters, not from front to back, but diagonally from center of the motor mount on one arm, to the center of the motor mount on the arm directly diagonal from it. \u00a0This will give you some general information about how big the overall frame will be so you know what to expect. \u00a0It will also give you some insight into how big a propeller the frame is meant for (most frames will let you know what size prop it is designed for). \u00a0Frames are often designed with a specific purpose in mind, either racing, or freestyle. \u00a0While you COULD do both with any kind of frame, the performance will often be biased toward one. \u00a0This is something to keep in mind when selecting your frame.<\/span><\/p>\n

of your multirotor, and is easily the most complex component of the flight system. \u00a0Built into the FC are sensors that tell the onboard firmware the orientation of the multirotor, and also takes in input from the pilot and using the two sets of data, sends commands to the motors to move the multirotor as commanded. \u00a0Flight controllers are complex pieces of equipment that can be programmed to varying degrees to essentially tune your quad just like you would a racecar. \u00a0You can also determine how much control you want to give your flight controller over the multirotor, such as allowing it to auto level your quad when not given a command. \u00a0Most pilots who fly FPV however fly in a mode called \u201cAcro\u201d which does not allow the FC to control the quad beyond user inputs. \u00a0It will basically only exert influence to maintain the position of the multirotor as the pilot has commanded. \u00a0<\/span><\/p>\n Read more about FPV Multirotor Drone Flight Controllers here.<\/a>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_single_image image=”153″

components on the multirotor that take the commands output from the flight controller and translate it into commands for the motors that tell them how fast to spin, what direction to spin in, and when to stop. \u00a0They do this by taking power from the power system and data from the FC and turn that into three phase electrical pulses that the motors feed off of. \u00a0By providing more or less power, the motor spin faster or slower in response. \u00a0Each motor of the multirotor has a dedicated ESC that drives it because in a multirotor flight system, each motor will almost always spin at different speed than its partner motors. \u00a0This is due to a multirotors flight characteristics, balancing, and outside influences such as wind. \u00a0Like the flight controller, the ESC has firmware that drives the calculations.<\/span><\/p>\n Read more about FPV Multirotor Drone Electronic Speed Controllers

multirotor into the air. \u00a0Most motors for multirotors are classified as brushless motors, and work by using three phase power to drive electromagnets that spin the motor. \u00a0While relatively small, brushless motors are fairly powerful. \u00a0These motors have been used in model aviation for many years, and are the components that draw the most power from your system. \u00a0Motors are rated by two size numbers allowing you to pick the size you need for your multirotor, as well as the Kv rating, which is defined as the RPM of the motor per volt. \u00a0As an example, if you have a 2206 \u2013 2450kv motor (a very common motor for 5\u201d multirotors), here\u2019s how it breaks down; the 22 stands for the diameter of the motor, the length in millimeters around the outside of the motor housing. \u00a0The 06 stands for the height of the motor housing in millimeters. \u00a0If you are running a 4 cell battery, the nominal voltage would be 14.8 volts. \u00a0Take the Kv rating of 2450 and multiply it by 14.8, giving you an RPM of 36,260. \u00a0This would be the maximum RPM under no load, meaning with no propeller attached.<\/span><\/p>\n Read more about FPV Multirotor Drone Motors here.<\/a>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/6″][\/vc_column_inner][vc_column_inner width=”2\/3″][vc_single_image image=”262″

provide the thrust of the flight system. \u00a0Attached directly to the motors via the motor shaft, they spin just as fast as the motors do. \u00a0There are many, many different styles and sizes of props out there, all made with different materials, different blade pitch, different blade shapes, and different number of blades. \u00a0Propellers are rated in terms of size, blade number, and blade pitch. \u00a0For example, if you have a 5 x 4.5 x 3, then you have a 5 inch propeller, with a 4.5\u2019\u2019 pitch, with a total of 3 blades. \u00a0The pitch is defined as how far forward the propeller will move in one revolution. \u00a0In the case of our example prop, it would move forward 4.5\u201d. \u00a0So all things being equal, a propeller with a 3\u201d pitch would not generate as much thrust as our 4.5\u201d pitch when spinning at the same speed. \u00a0The material that the propeller is made of will also affect the durability of the prop when it hits something such as a tree branch or the ground, as well as change the weight of the prop itself. \u00a0Spinning a heavier prop will also consume more power from your multirotor, so you have to find the right balance here.<\/span><\/p>\n Read more about FPV Multirotor Drone Propellers here.<\/a>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner

controller and feeds that information into the flight controller. \u00a0Here, you want choose an Rx that matches up with your radio controller, often determined by brand and or model of controller. \u00a0There are many brands of radio controllers out there, and this is often up to a pilot\u2019s preference. \u00a0You want to select a radio system that fits your needs in terms of features, size, ergonomics, and range. \u00a0When it comes to selecting a radio receiver, this generally comes down to features and size, as well as latency of the overall control system. \u00a0Latency basically means how long in milliseconds it takes for your commands from the controller to be implemented on your multirotor, and standard logic applies that lower latency is better. \u00a0<\/span><\/p>\n Read

[\/vc_column_text][vc_column_text]<\/p>\n The flight camera is your window to the world of FPV. \u00a0Through it you have access to a remote eye in the sky that will bring you on board your multirotor. \u00a0There are many different types of FPV cameras, and most of them owe their creation to security camera technology. \u00a0From that, many companies have developed FPV specific cameras of various sizes, quality, ranging from basic 600tvl standard definition cameras, cameras that specialize in low light situations, and HD cameras with 1080p resolution. \u00a0One thing to remember though is that the more information the camera provides, the more potential latency you introduce into the system. \u00a0\u00a0\u00a0<\/span><\/p>\n Read more about Multirotor Drone FPV Cameras

the video from your flight camera out in a way that your goggles or ground station can capture it. \u00a0They range in size, power, and features, and provide the pilot with the wireless technology that makes the entire FPV system possible. \u00a0They are designed with many possible frequencies that can be used both to work in the environment that you fly in, as well as make it possible for many pilots to take to the sky all at once. \u00a0The VTx is rated in terms of milliwatts (mW), which gives the pilot an idea of how far the VTx can transmit. \u00a0Proper management of your VTx is one the finer points of learning to fly in groups, as well as just good manners. \u00a0Bad management of this single component can lead to causing accidents among your fellow pilots as well as some hurt feelings, so be careful.<\/span><\/p>\n Read more about FPV Multirotor Drone Video Transmitters here.<\/a>[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner

station and a monitor to fly FPV, that option is not quite as immersive as using a set of goggles. \u00a0There are many different styles of goggles, ranging from DIY versions that you can assemble yourself, to ready to go models with a ton of features, such as DVR capabilities. \u00a0These function similar to virtual reality headsets, in that the image is displayed on a screen directly in front of your eyes, making you feel like you are a part of you multirotor as it speeds through the skies. \u00a0The googles have a component called the Video Receiver (VRx) that like any other FPV component, comes in multiple styles and capabilities. \u00a0Attached to them is an antenna, very similar to the one attached to your VTx on you multirotor, but again come in different types, styles and technology that determine how far away you can fly your multirotor from where you are at. \u00a0<\/span><\/p>\n Read more about FPV Multirotor Drone Goggles

wiring of a multirotor tremendously. \u00a0Not that long ago, multirotor components got their power by a complex system of wiring all the components directly together in a system called a wiring harness, but then power distribution boards came into favor. \u00a0On the board, the battery is wired to the board through a connector, and from there, your components are all wired into the board. \u00a0The board very simply provides power to all the components. \u00a0There are several features to some boards just beyond simple power distribution, such as power filtering that helps keep the power going to your components \u201cnoise\u201d free, providing cleaner, more reliable power. \u00a0They also have features that can provide power of different voltages to different components, to help keep components effective at their optimum voltage levels.<\/span><\/p>\n Read more about FPV Multirotor Drone Power Distribution Boards

your multirotor and can have a huge impact not only on how long you fly, but how powerful your total multirotor is. \u00a0Multirotors are generally powered by a battery technology call lithium polymer batteries, and are made up of individual cells. \u00a0Each cell have a voltage rating of 3.7 volts, and by adding more cells to the battery, you add more voltage. \u00a0If you remember our conversation above about motors, the speed at which a motor spins is dependent on how much voltage the motor is provided. \u00a0The more voltage, the faster the motor is capable of spinning. \u00a0Choosing the right battery is also a very fine balancing act in terms of weight vs. power. \u00a0The more weight you add to the multirotor, the shorter the flights, and the more weight the motors have to push around. \u00a0Out of all the single components, the battery will add the most amount of weight to your multirotor. \u00a0Batteries are rated by both voltage and amp hours. \u00a0Amp hours tell you how long the charge on a battery will last while under load; the higher the amp hours, the longer they will last.<\/span><\/p>\n Read more about FPV Multirotor Drone Batteries
