Update 12/14/2016 – Updated the build list to suggest BLHeli_S ESCs which will support the upcoming DShot protocol.
Welcome to the first part of our drone racer build guide! In this series of articles, we are going back to the basics and giving detailed instructions on how to build your first racing drone. This series is structured for beginners, so those of you who have been in the hobby for awhile might want to skip it.
If you are looking for a specific part of the process, all the sections are listed below:
- Part 1: Introduction (this post!)
- Part 2: Frame assembly
- Part 3: ESC installation
- Part 4: Electronics
- Part 5: Finalizing and cleaning your build
- Part 6: Adding an FPV system

What is a Racing Drone?
A racing drone, like the one pictured above, is a small remote-controlled quadcopter built for high speed and agility. They generally have a camera and a video transmission system so that they can be flown first person from a set of goggles like those sold by FatShark:
These aircraft can be flown everywhere – inside your yard, in a forest, in an urban setting, or out in an open field. They offer you the ability to safely experience flight in a way that has never been possible to humans before. I have been piloting remote controlled aircraft for more than a decade, and drone racers are by far the most fun I have ever had. If you have fun flying the toy quadcopters you can buy at most electronics stores – I can guarantee that you will have a blast flying a drone racer.
Here is what it looks like to fly a racing drone:

Getting your Gear
When picking up parts for your quadcopter, there are a ton of options. Over the past few months, we’ve written several buyers guides that cover nearly every component that goes into building a racing drone. This would be a great place to start so that you can become more familiar with each of the parts that make up the final quadcopter. For your first build, we strongly recommend you follow a few additional guidelines to make your life easier:
- Buy a frame with a good build log you can find online. You can find build logs by simply searching “<your frame> build log” on Google. This will give you something to follow when doing your build.
- Buy 2205 motors known to fit your frame. You don’t want to have to modify your arms on your first build. Learn more about motor sizes in our motor guide.
- Buy reliable ESCs that run BLHeli. Good ESCs are the most important part of a racing drone – don’t skimp!
Our build for this guide and where we got our parts
You don’t have to break the bank in order to have a fantastic drone racer. You can build a quad that performs identically to the those that the pros fly for under $200 (without the video system). which is exactly what we will be creating through this series of articles. In the final article in this series, we will add in a video system to allow for FPV supported flight. Why start the build without FPV? We explain this in our guide on how to get into the hobby. You can buy all the non-FPV components pictured above at Banggood with money to spare for your RC receiver while staying under $200.
Banggood is a retailer shipping out of China that has a lot of similarities with Amazon here in the states. They carry a huge stock of all types of items for extremely low prices. In particular, they are known for stocking quality drone equipment. Unlike most Chinese retailers, you generally won’t spend more than $5 for “priority shipping”. In the United States, you will generally receive your items within a week if you pick priority shipping. They also have very good customer service which we have dealt with in several circumstances. Finally, by buying Banggood items from our links, you will be supporting our site – this is how we pay the bills, and it doesn’t cost you a dime!
For these reasons, we recommend purchasing your first kit from Banggood if you are on a budget. We also list other great vendors in the hobby on our vendor page if you want to shop around.
If you want to follow along directly with our guide, we recommend you use the parts found in the build list below. Please note that we may update this from time to time to make sure you are getting the latest and greatest technology. These changes will always be confined to updates to the ESCs and motors, though, and will not effect the build instructions to follow.
|Lisam LS-210 Frame||$15.99||Here|
|Emax RS2205 2300kV "Red bottom" motors||$62.99||Here|
|RacerStar 30A BLHeli_S ESCs||$49.00||Here|
|SPRacing F3 Clone||$19.99||Here|
|Matek Basic PDB||$5.60||Here|
As a final note – we are going to endeavor to keep the instructions founds in this article as general as possible. If you follow the guidelines above, you should be able to follow along with our guide no matter what parts you buy. You may notice that the frame listed is very similar to other kit builds in the hobby at the moment – namely the “Dubai 210” kit. This guide would also serve as a suitable Dubai 210 build log.
Using the proper tools is just as important as using the correct parts. We have an entire article on tools you will want when building quadcopters, or you can reference the picture above. For most beginners, this will be the first time buying and using a soldering iron. If it is your first time, you should take some time to get familiar with it and do some practice sessions with some disposable equipment so that you do not ruin your shiny new racing drone. We have an article on getting started with soldering that offers some exercises that you may find useful.
There are a few “consumable” items you will need to properly finish any quadcopter build. These items include:
- Zip ties
- Small heat shrink
- Large heat shrink for ESCs
- Servo cables
- Battery wires
- XT-60 connectors
- Nylon standoffs
- Double-sided tape
Many of these items can be purchased from your local hardware store. The ones that cannot, like the props and connectors, can be purchased at any big online retailer like Banggood, Amazon, or eBay.
To save yourself some frustration while building, we recommend you get all the above parts, tools, and consumables together on your workbench before you begin doing anything. Once you’re ready, continue on to the next article where we will assemble the frame!
