Get Your FPV Build Started!
There are a couple things you have to ask yourself before you get started building a drone.
First! What is my drone going to Do? What type of task is my drone going to perform?
This gives you an idea of where to start and a jumping off point for creating a parts list.
This is a very important question because if you want a heavy lift drone you probably aren’t going to put racing motors on it. The opposite is true as well. If your’e looking to but a racing drone, your’e not going to put a 20,000mah battery on it. Or will you? 😉
You need to have a clear vision for the task your drone is going to accomplish because that will help you find the most efficient or event just the right ball park parts you’ll need to make it fly.
Second! How big is my drone going to be?
Maybe your’e looking into the freedom class drone racing in which your drone will be much bigger than the average racing drone.
No matter the size, task, type, shape or speed of your drone, the basic functionality will be the same across the board. The titles of this list make up the list of parts needed to build your drone. We will be sticking with FPV racing parts but you will either scale up or scale down as needed on the sizes
What is FPV?
“Fpv” stands for (First Person View). This means there is a camera on the drone pointed forward which send a video signal back to a set of goggles you wear. This whole experience is makes you feel like your’e flying in the drone while you control it. While the most common place you see this used is in FPV racing The term “FPV only refers to the use of Camera Transmitter and screen or goggles giving you the ability to see what the camera sees. This means you can add “fpv” to just about anything as long as you have a 5v-12v power source.
There are three main points that are important in picking props and a fourth if your’e going to get extremely technical.
Props Size- This ranges across the board so its safe to tell you that they start at about 31mm which is used on the Tiny whoop, E010 and inductrix sizes brushed motor drones. (frames sizes ranging from 55mm to 90mm. The frame sizes will very on each prop size but this is what everyone generally uses to get the right frame/prop sies. “The biggest prop on the smallest frame and as long as the prop doesnt touch anything then you’re good.
55mm -75mm props (frame size ranging from 90mm to 140mm) Using brushed motors
1″ and 2″ props ( uses on 90mm to 150mm size drones) using “brushless” motors
Prop Type– The most widely known prop types used in the fpv racing industry are Dual blade, Triblade, Quadblade, 5blade and hexblade props. The single most common are triblade props. they’re stable, they balance out your motors giving you a smoother flight and they provide a little more thrust than Dual blades.
Pitch- This is the angle up the blades are designed. The more aggressive the pitch the more thrust your props will produce BUT it will also work your motors harder also. The harder your motors work the hotter they they get. you will also pull more amps through your ESCs.
Motors come in a million different sizes but if your’e looking in to fpv racing you’ll be safe and very competitive if you stay in the 2200 – 2400 series motors and then if you KV (Kilivolts) is with in 2300kv – 2700kv you’ll be safe. the higher KV ratings make it a little harder to tune but with practice it all become second nature.
Note: when you start getting in to the larger drones keep in mind that as your props get bigger and your motor gets bigger your kv will usually go down.
ESCs (electronic speed Controllers) do just that. they controller the up and down speed of your motors. For fpv racing youre safe if you stay in the range of 25amp -35amp ESCs. This will be determined by the size type and pitch of your props and the size of your motors. most everyone is running 30amp or 35amp.
There are a couple types of ESCs. ALL in one (all four escs are part of the same board and get stacked under or above the flight controllers) OR Individual ESCs (which usually get places out on the arms or somewhere away from the center.)
Frame is literally personal preference but the design does matter. Everyone and their mom has there own frame designs so it will take you a few runs to find what types of frames you like and what feels good. there are a few different types of frames.
There use to be H frames but those lost popularity a while ago. (by a while ago i mean like last week.) things move so quickly in this industry that there are a number of band wagons going at once.
(Power Distribution boards) These are still around and they do just that. distribute power. to the escs to the camera to the flight controller to leds. to any thing that needs power. recently there have been a slew of flight controllers that have the PDB integrated into them. its all in one.
There are a bunch of different flight controllers. Your flight controller runs an internal gyro that sends information about the drones positions which is sent through an algorithm programmed into the firmware that gives it the ability to fly. You can tune and program your flight controllers using a few different configurators.
These run their own Firmware on the Flight controllers. Some are easy to use some are more complex but they all essentially give you the same abilities. To make adjustments.
(Video Transmitter) This broadcasts your camera signal over a 5.8ghz frequency to your monitor or goggle. The is what FPV is all about the term FPV stands for First Person View. (make sure you have an antenna attached or you run the risk of frying your VTX.
The camera on your drone simply captures video at 700tvl or higher and runs on either a 5v or a 12v power source( always make sure you check before plugging it in. )
there are a few different antennas out there. Circular polarized and directional.
This binds to your remote usually on a 2.4ghz band. this is how the remote is connected to the drone giving you control.
The remote is the transmitter that allows your stick movements in your hands to be translated into drone movements while your’e flying.
Your goggle or your monitor are how you view the camera that is being transmitted from your drone. There are a few different goggles out there and it may take you a bit to find what fits you best.
they’re all very good but its going to depend on what you’re most comfortable with.
I will be slowly making this list more complete. adding picture, video links and going into a bit more detail stuff like that.
