Introduction: Build 250 FPV Drone in Sample Steps

As it is generally known, a drone is a helicopter and several rotors are responsible for lifting and propelling it. If you are a lover of this magical artifact and have a great desire for building your own drone from scratch this guide is just for you because here we will cover all major concepts.

Step 1: Pick Up FPV Package

Nighthawk 250 package

In the content of this package you will get 4 * 12 am ESC, CC3D flight controller, 6030 fiber props, four 2204 2300 kW motors and the last, but also the most important one is a full carbon fiber frame, with a bag of hardware. Here are all the screws, dampeners for the camera mounting and the carbon fiber body parts. In the package you can also find all necessary instructions. Build your own drones You need not only to have EMAX kit, but also some other parts to make your drone fly.

Step 2: Choose a Transmitter

The first one is a transmitter. It is a good idea to have a transmitter

with at least six channels, you can also have one with four channels but in that case you cannot set up flight modes, discovery buzzer or anything else. Terranis x9d is a good and a little bit expensive one. However, it is very powerful, so you can do almost everything with it. For example, simply program it to speak to you.

Step 3: Choose a Receiver

Next, Building your own drones you need a receiver for your

transmitter. You should use Sky d4 , because it supports telemetry and CPM telling you the RSS (radio strength signal indicator). It shows how strong your signal is. With this you can be warned when your signal is low. To connect your transmitter properly all four wires should be connected to the transmitter.

Step 4: Choose Lipo Battery & Others Parts

Another necessary part is choosing the best lipo battery with trungy nano-tech or Tattu, because they are powerful enough to make your flight possible.

Others For FPV part you should use camera for video transmitter. Immersion RS 5.8 is a great choice, because it normally provides the cleanest signals. To use transmitter and get the signals you also need an antenna. For a monitor part, you should use Dominator v2, which gives a clean picture. You can also put a memory cart there recording exactly what you see through to the monitor. In EMAX package you can also find CC3D flight controller.

Step 5: Connecting

After getting all necessary parts from your package you should screw the arms to the actual body frame.
Constructing or diy drone you need to start off screws from the top, put arms on which goes over the buttom part of the frame you add all locking screws. You should connect all arms to the body using screws, and bullet connectors to the motor cutting down some of the power wires. Then, shorten all unnecessary power wires and make ready to be mounted on the power distribution board.

Mount the ESCs under the main frame to minimize the wires and it makes it easy to solder the wires. Shorten the power and ground wires so you can solder them on the pads. If you decide to mount the ESCs on the arms you’ll probably have to solder the motor wires directly on the ESCs. There won’t be enough room for the bullet connectors. Run the signal wires from the ESCs under the PDB so you can connect it to the FC on the other side.

Step 6: Set Up Receiver

To do that you have to plug in your power to your drone and make some changes to make it work in a correct way. After this test the motors. In your configuration file, there is a diagram which shows the direction that the baby part of the frame should be spinning toward. The first and fourth spin clockwise, the second and third spin counterclockwise. Going back to motor testing part you can manually test the motors individually turning on and off the voters.

Step 7: Calibrate the Accelerometer

To do that you leave your drone completely flat on the table and you go to configurator enabling some features such as TPM, leave the battery voltage monitoring, do not spin the motors.

By default the voltage of the battery will be 3.3, but because you should use 3-cell, put the voltage to 10.4 volts.

Step 8: Conclusion

Why take Nighthawk 250 to build your own drone, because FPV 250mm is more and more popular at the moment.

And that’s it. We now have a fully built Nighthawk ready to be programmed via PC software.
