Intro: How to Build a Racing Quadcopter

Hello, today I will teach how to build a racing quadcopter!

What is a quadcopter?

A quadcopter is multi-rotor copter with four arms, each of which have a motor and a propeller at their ends. Quadcopters are similar to helicopters in some ways, though their lift and thrust comes from four propellers, rather than just one. Control of vehicle motion is achieved by altering the pitch and/or rotation rate of one or more rotor discs, thereby changing its torque load and thrust/lift characteristics.

What is a "racing quadcopter"?

Quadcopters are very useful and have many different types, for instance quadcopters can be made for filming and lifting cameras or built for doing mid air acrobatics. Well a racing quadcopter is a quadcopter meant to go fast. Extremely fast. Racing quadcopters can also be entered in competitions where they are put into different classes, the most popular is the 250 size.

Are they expensive or hard to make?

It depends, a typical cheap quadcopter will cost you about $120 - $200. However a more expensive quadcopter could easily cost you around $1000. Anyone with some previous electronic background should have no problem building on.

If you don't want to risk building one, message me or comment below. I can build you a reliable drone for a reasonable price!

Step 2: What Do I Need?

  • 4x 1806 motors, My motors were extremely fast at 2400kv,
  • 4x 12a ESC
  • 1 RC transmitter and receiver
  • 1 Flight controller (Flip 32, Naze 32) You can even use an Intel board!
  • 1 Lipo battery (3c)
  • 250 Quadcopter frame
  • Wires
  • Computer with Clean Flight
  • Assorted tools

Optional

  • Fpv Camera
  • Fpv transmitter and receiver

Step 3: Frame

Now its time to start!

Start by rough building you frame and attaching motors to the arms of the quadcopter.

When you are done, You should end up like the last picture.

Step 4: Solder on ESC

Now trim away excess wires and attach the motors to the esc's by soldering them.

I recommend using flux to stick the wires, because I did not (see pictures) and my soldering ended up terrible, I had to restart later and solder them again.

Hold the esc in place with a ziptie

Step 5: Program Flight Controller

Now its time to program the flight controller

Flash the board using cleanflight, and make sure all the settings are correct. Its very difficult to explain this process in writing but Its not that hard, If you are still stuck there are hundreds of tutorials on YouTube.

Step 6: Wiring

This is where things might get confusing.

I have added a diagram (not mine) that helped me when I made my quadcopter, Ignore the part about the leds

Notice how two wires have been reversed. This switches the motors direction on the quadcopter in order to lift it into the air.

Step 7: Testing and Debugging

Now its time to test and debug the quadcopter.

using the assorted tools on clean flight, check everything is working

Most important:

  • Reciever
  • Motors
  • Mode

Step 8: Add Battery

Now simply plug in your battery and let the flight controller calibrate itself for about a minute.

Most people put their battery inside the middle of the quadcopter, however I dont like to. I like to keep the more sensitive electronics inside the frame for when you crash (Yes, you will end up crashing at some point). Also I like to believe that it makes it faster, but that has not been proven yet.

Step 9: You're Done!

You're done with you quadcopter! Go and fly it!

Some tips

  • Most transmitters have a motor lock and unlock
  • Fly in open fields
  • Use a Lipo alarm
  • Charge Lipo in Lipo safe
  • Be careful

Thats it go and fly your quadcopter!

Remember If you dont want to build one. Message me, I can build you a reliable and cheap quadcopter!

I am a total noob, so this question might be really stupid. I am wondering what I plug the battery into? I have the battery and the flight controller and the RC receiver. How do I connect them? the receiver has 7 rows of 3 pins, the rows are ch1-ch6 and BAT. what does that mean? I am using the Naze 32 flight controller, how do I connect it to the receiver? Do I just solder jumper wires from one to the other? Also where do I plug in the ESC wires on the flight controller? Thanks again!

Hi, could you recommend me, a good kit to start, I already bought my soldering iron, but I'm not sure what size soldering to use.
Thanks

Do you make security drones? If you do how much would one be if it was tethered and had a weather proof infrared camera and could comfortably cruise around 15 meters? Please let me know, thank you.

If you are tethering a drone, then you should consider making the tether into an umbilical, providing power from the ground. 15 meters of cabling will not be light either, but may offset battery weight. Of course, extending flight time thanks to more power may overheat motors, but it would be fun to try.

I have never heard of a security drone. I understand what you are tryin to say but the longest the battery would last for would probably only be about 10 minutes

What I mean by security drone is a drone with a camera that is well, meant for security. I was just wandering if you had some sort of pricing for that. If you could do that sort of thing.

Thermal imaging cameras are pretty expensive. They have a NoIR camera module for the Raspberry Pi, but I'm not sure how well that works.

not sure if they exist, but an integrated board with the controller and four servo controllers might be useful since it would save on weight and having a lightweight camera.

build a bigger size octacopter or hexacopter , and u will also need a bigger prop , if u need a longer flight time with about 20_30 minutes, add 2 5000 mA battery on it , there are contoller now days which can controller up to 1km (i am using a MC6B which can control up to 800 metre and 900 metre without obstacle ) , i suggest u to use the apm flight controller with gps so that u wont loss ur copter easily , and also apm come with a feature that u could use them as a gimbal controller , so u could have a greater vision from ur fpv

You don't have to keep the batteries onboard if it's tethered. This has been done before but probably not in instructables. I know at least one that makes tethered drones with camera like this but it's for military applications only.

how many cell in your battery....

i mean voltage level of battery.

i am going to make one need suggesting regarding battery selection

how much flight time you achive ..??
