So you are new to Drone Racing (aka FPV Mini Quad) and wondering where to start? I created this guide to help explain the basics of buying, building and flying a drone. I will also recommend some other great resources related to FPV mini quad throughout this tutorial.
In this guide, we’ll cover the following topics:
- Racing Drone Overview
- Build one or buy one?
- Drone Simulators
- Parts and Equipment
- FC/ESC firmware
- FPV System
- Practice with micro drones
- Going to meetup and race events
What is Drone Racing?
Drone Racing is like racing roller-coasters, just without the tracks. The remotely piloted drones race together at high speed through a 3-dimensional course of obstacles and gates. It’s one of the fastest growing sports in the world, attracting big corporate sponsorship deals, and with over 40 million online viewers in 2016 you can see why.
It doesn’t matter if you are piloting or just watching a drone race, the true joy is in experiencing the neck breaking acceleration and agility from the aircraft’s perspective through the immersive virtual reality style goggles.
What is FPV?
FPV stands for First Person View. Basically it means putting a camera on the drone, so you can see what the drone sees while controlling it. It’s like you are sitting in the cockpit and flying like a real pilot, but your feet are actually firmly on the ground.
Flying a drone in FPV is the most surreal experience I personally have ever had. You can go anywhere in 3D space, what you can do is totally up to your imagination.
Flying FPV feels a bit like a video game, except it’s real. There is no “reset button” and you could damage your drone in a crash, not to mention the damage or injury that could result in losing control at these speeds. It’s the adrenaline rush that makes it such an exciting experience.
Flying Mini Quad as Hobby
More and more pilots are now racing drones on a professional level, but the majority of us just fly them on our days off as a hobby.
The FPV Mini Quad hobby has some of the most friendly online communities I have ever experienced. Everybody helps each other out, and our local group regularly meet, fly and race together.
With the help of this guide, you learn to choose parts, build and repair your own quadcopter. You will also learn to tune your drone to fly exactly the way you want it to. Everything in this hobby is highly customize-able and upgrade-able.
Racing Drone Overview
Let me cover the basic terms used in this hobby to avoid any confusions later on.
What is a Drone?
The word “drone” is being used a lot these days and has become synonymous with any unmanned aircraft with an onboard camera, and sometimes a camera is not even necessary for the title! Other than for military use, most “drones” were historically used for aerial photography (AP) and were large with a heavy payload capacity for carrying cameras and equipment.
Here is a list of drones that are commonly seen in this hobby.
What is a Multirotor?
The word Multirotor (or Multicopter) covers anything that is a “copter” with more than 1 main motor or propeller. For example, a “tricopter” has 3 motors / rotors, a “quadcopter” has 4, a “hexacopter” has 6 etc. But these are all “multirotors”.
Here are the different configurations of multirotors.
What is a Mini Quad?
A Mini Quad is basically a small multirotor, or more specifically, a quadcopter.
Mini quads are designed to be fast, nimble and crash-resistant, so even when you crash you can usually just pick it up and take off again. This resilience gives pilots the confidence to fly faster, through smaller gaps, and continually push their limits to the next level.
Since this fantastic invention, we’ve seen huge progress in the power of these mini-quads, increasing propeller sizes, higher battery voltage, larger motors, all coming together to give insane power-to-weight ratios of over 15:1! Turning these little toys into insane rockets, the fastest racing drone in the world is capable of reaching 180mph(~290Kmh) in a matter of seconds.
How Much Does It Cost?
Building a drone for the first time is not cheap because of all the tools and accessories you have to buy. Just like anything else it largely depends on your choice of components.
To give you a rough idea, an FPV racing drone typically costs somewhere between $200 to $500 (there is no upper limit really). That is just the mini quad itself and doesn’t include other necessities like batteries, FPV goggles, radio controller, building tools and other basic accessories can cost another $200 to $500.
With the growth of the hobby, there are cheaper options hitting the marketplace all the time, and it’s becoming much more affordable now than when I started back in 2013. Competition is driving the price down for every type of component, parts are better designed and more robust. A good example would be the durability of the propellers, now I don’t have to change them for days, compared to the 10 props I used to break every session.
Building From Scratch or Buy Pre-Built?
If building a quadcopter from scratch sounds too challenging, there are pre-built models available. However I do strongly recommend building your first drone! Building is a big part of the fun and the skills and knowledge you learn along the way will enable you to diagnose, repair and upgrade your mini quad later on.
Whether you are buying a pre-built drone or building it yourself, you should make a shopping list, and have it checked by someone experienced. If you want to find someone to provide advice before you decide, or help you select components for you to build your own, ask the 3000+ members at IntoFPV forum. We have a wealth of experience and are always ready to welcome new members and answer questions.
Get a Taste of Flying in Simulators
“I don’t even have a drone yet, how can I learn to fly?”
You don’t need a drone to learn flying these days, there are many FPV simulators available for you to practice on. Simulators can teach you the basic controls of a drone, and the muscle memory your hands require. You will be able to use the same radio transmitter to fly the simulator, and the real drone so there is no need to adjust between different controllers.
Speaking from experience, I don’t think it’s wise to learn to fly on a full size mini quad. You will crash a lot in the first few days, and it’s dangerous and expensive if you crash and damage the parts. As you practice more, muscle memory will take over and you will crash less. Practicing in a sim in advance can accelerate that process and prepare you for it.
Here is a list of FPV flight simulators for Drone.
FPV sims are probably the cheapest way to get into quadcopter flying. You can practice anytime of the day regardless the weather. It’s not exactly like flying in real life, but it’s close enough as basic training. I recommend spending 5 to 10 hours in a simulator before attempting to fly a real drone, this will help you tremendously as a complete beginner.
To fly FPV simulators, the first item you should buy is a radio controller (aka transmitter). Make sure it supports FPV simulators, many of these are plug and play without any dongles or adapters. You can use the same transmitter to fly your drone later.
Don’t use XBox console or keyboard because it’s pointless. Only using a proper transmitter will build up muscle memory and provide the full benefit of training.
What radios should you consider? Here are my personal recommendations. These are the most popular options in the hobby and you won’t go wrong with them.
- Cheapest options: Taranis Q X7, Jumper T12
- Best feature-rich options: Jumper T16, Taranis X9D-Plus
- Compact option: Taranix X-Lite
If you want to dig deeper into what makes a good TX for mini quad, here is a buyer’s guide of how to select radio transmitters for FPV.
Mini Quad Sizes
The size of a mini quad is determined by the maximum propeller size it supports. For example, a 3″ drone spins 3″ propellers.
As your first build, I strongly recommend building a 5″ mini quad because it’s the most versatile platform for both freestyle flying and racing. It’s the most popular size, so advice and build logs can be easily obtained online.

Take a look at the gear I use and quads I fly, this might give you some ideas.
There are quite a few different flight controller firmwares available for a mini quad. My personal favorites are Betaflight, KISS and Flightone, they all perform really well, being frequently updated and have a large user community for supports. Choose one of the three to begin with, you can’t go wrong with any of these FC firmware.
ESC Firmware and Protocols
Every ESC has its own processor and there is “ESC firmware” running on it. Flight controllers communicate with ESC’s using “ESC Protocol”.
Check out this post to learn more about ESC firmware and protocols.
How IS A Drone Controlled?
The Pilot controls the drone using a radio controller which has two joysticks. The stick commands are sent wirelessly to the radio receiver installed inside the drone.

How Does a Drone Stay in the Air?
[pic] LiPo battery powers ESC, FC sends signal to ESC, ESC controls motor/propeller speed
The flight controller takes commands from radio receiver, combines with data from the gyro sensor, and calculate what speed each motor should move
The ESC converts this signal from the FC, and controls how fast the motors should spin, in order to generate the correct thrust desired.
A drone is normally powered by a LiPo battery.
How is the Pilot Getting Video from the Drone?
The FPV system on a mini quad is actually quite simple:
- There is a camera connected to a video transmitter (VTX)
- The VTX broadcasts video feed wirelessly to a video receiver (VRX) which is built into the FPV goggles, or connected to a monitor
Read this FPV guide to learn about FPV systems in more detail.

5.8GHz (5800MHz) is the frequency band that we commonly use for broadcasting the video feed. The frequency we use for radio control is on 2.4GHz, so there is very little interference.
Typically video transmitters and receivers support 40 channels or more. This allows multiple people flying at the same time. Spectators can also tune into drones that are flying and watch the actions in real time.
Use a low power VTX!
Some countries (e.g. UK) have a transmission power legal limit of 25mW for 5.8Ghz frequency, using higher power than this requires a HAM radio license.
For racing, a higher power output such as 200mW is more favorable than 25mW as it will stream a more reliable FPV feed further and with less interference from obstacles. 200mW is also preferable to 600mW if you want to fly with other people. 600mW is too powerful and will cause lots of interference for other pilots.
If you crash, unplug your LiPo as soon as you pick it up. If you walk back to your seat with the quad powered on, it might affect your buddy’s video signal if they are still flying (because your transmitter is now closer to your friend’s receiver than their own quad is).
Use Circular Polarized Antenna
Although most VTX and VRX come with dipole antennas, we recommend getting some “circular polarized” antennas for your FPV gear instead. They provide better range, reliability and less interference (for you and others).
Find out more about the benefits and negatives of circular polarized antennas.
Flying FPV with a Mini Quad
It takes time to relate what you learn on a simulator to a mini quad in real life. Don’t worry it might take a few days, then it will just click and all of a sudden the sky becomes your oyster!
Here is an article about learning FPV flying, and here are some motivation and advice for learning FPV. BigglesFPV also wrote a few excellent articles about getting into FPV on the IntoFPV forum, check it out:
And you also need to learn how to tune PID when learning how to fly.
Don’t Fly Auto-Level Mode
If all you want to fly is a DJI drone, or other GPS assisted multirotors, auto level is perfect and it’s fine to just fly like that. But if you want to get into racing and freestyle flying, you have to learn to fly in acro mode.
This article explains the differences between acro mode (rate mode) and self-level mode.
Acro mode might seem hard at first, but once you have learned it you are free to control your quad exactly how you want it. Auto level is like a pair of crutches, great if you can’t balance yourself, but try using them while running a 100m sprint! Once you have learned acro mode, auto level will feel like a hindrance, it can also teach bad habits which can be difficult to shake.
While learning how to fly in a simulator, you should also start doing research on quadcopter parts, and plan your build. Move on to the next section to learn more about parts and equipment.
How to Practice Flying Without Simulator?
If you find simulators a little boring or don’t have a high enough spec computer to run them, you could consider learning on smaller models like a tiny whoop, or micro drone.
Check out this guide to learn about how to pick your first toy drone and start flying.
Starting out with a micro quad is not my first recommendation though since simulators are getting quite good these days. Not to mention micro quads fly quite differently than something larger (such as a 5″) due to the much higher power levels. The power of brushless micro’s are starting to rival those of their bigger brothers now, and they are getting cheaper these days. However, shelling out for spare parts, extra batteries and accessories for one drone is enough of an investment in the early days.
Attending Meetup and Race Events
As you arrive at the FPV site, first thing you want to do is to work out who is using which video transmitter channel.
DO NOT power on your quad before you get your video channel confirmed, especially when there are other people in the air!
When 2 quads are on the same VTX channel, or when frequencies are too close to each other, one can disrupt the video feed of the other. Interference on 5.8GHz frequency can cause accidents because the image in the goggles can disappear entirely while flying, leaving a pilot “blind”.
Always warn other pilots before you power on your quad.
Even if you are not on the same channel, some low quality VTX can emit power through the whole spectrum on start-up and changing channels. This can cause a split second of interference to everyone else.
Alternatively you can always switch on your video receiver first, and check which channels are being used before you switch on your video transmitter.
With proper equipment and frequency management, normally up to 8 people can fly at the same time, but typically 4 pilots is more common for an interference free race.
Safety should always come first.
Remember that these racing mini quads are really FAST and powerful! They can cause some nasty injuries to people and animals, and damage to property. We have zero tolerance for people ignoring safety rules, because it does not only affect the pilot and victim, but also the reputation of this hobby.
- Check your local rules and regulations regarding FPV, RC and Model Flying in general
- Buy Insurance!
- Get a spotter, or a fly buddy!
- Choose your flying location sensibly
- Never fly too close to or above people and animals
- Disconnect battery immediately after picking up the crashed quad
- Do not try to catch a multicopter in mid-air
- Never use damaged LiPo, and dispose of LiPo battery properly
Please also read about this article that explains FPV safety in a bit more detail.
Best Configuration for Drone Racing – Quadcopter or Hexacopter or Tricopter?
Personally I prefer quadcopter especially mini quad.
Quads are easier to build and maintain, have many different options for frames and are most common when it comes to seeking advice. A quadcopter is also a great balance of power, weight and efficiency.
Although with the same motor/props/battery, hexacopter can give a higher top speed, but every time you crash you have more chance of damaging propellers, motors and arms.
Tricopter is pretty energy efficient, and has the best yaw authority of the three. But the yaw servo can get damaged easily in crashes, and i just don’t think they are as fast as a quadcopter for a similar setup.
Tips about Mini Quad Racing
Winning a race, is not all about speed, consistency is king. But most importantly, stay in the air!
Sometimes it’s better to go slow and steady, rather than going too fast and getting out of control. So many times I have seen the fastest pilots get defeated by a crash in racing.
Make sure you bring spare propellers, crashes are inevitable no matter how much experience you have. Be prepared to crash, props and parts can get damaged, it happens to every pilot and it’s completely normal. You will only start pushing your limits and improving your skills more quickly once you stop worrying!
