Build Your Own FPV 250 Drones

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 creating your personal drone from scratch this guide is just for you because here we will cover all major concepts. Introduce building your own drones FPV just in a few simple steps, After mastering some simple techniques, you will be able to build your own FPV drone.

Build your own drone what do you need?

#1 Nighthawk 250 package

Nighthawk-250-Building-your-own-drones-2In 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 the necessary instructions.

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 bottom 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.

After this connect the battery cable to power distribution board so you will have to find positive and negative connection pads. That means negative should be connected to negative and positive should be connected to positive as well.

Mount the motors on the drone. In your EMAX kit, there are clockwise and counterclockwise proper motors which you also should connect to the arms of your frame. In this part, we shall connect all signal wires into the knees, and a receiver.

#2 Transmitter

3The 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.

#3 Receiver

4Next, 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.

#4 Lipo battery

Another necessary tool is a FPV battery with Trungy nano-tech or Tattu, because they are powerful enough to make your flight possible.

#5 Others (Camera, Antenna, etc.)

For FPV part you should use the camera for video transmitter. Immersion RS 5.8 is a great choice, because it normally provides the cleanest signals. To use the transmitter and get the signals you also need an antenna. For a monitor part, you should use Dominator v2, which gives a clear 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 by Step – Building your own drones

#1 Set up

Build-your-own-drone-1Set up a new model for your new drone. Go to menu, scroll down enter button and here create models. Also disable a switch warning, select model, hit page down. It is important to name your model.

After this bound your receiver to the remote. For this go down page two on your transmitter, change the mode from d16 to d8. To buy your receiver to your transmitter hold button on d4 and power up drone at the same time.

For making it easy just unplug the wire first and when you plug it back make sure you have the signal on the right power, in the middle and the ground on the left. When your transmitter turns on select bind and it will start beeping telling you it is in a bind mode.

Then power up your drone holding the d4 button at the same time, plug in your power to flash, hit enter and exit out.

After this it is time to connect the base fly. For this you need to download all necessary drivers enable the base file to communicate with the whole structure. After installing the drivers go to your computer and launch them, which are automatically set auto connect.

Make the pointing direction of your drone matching the one in the configuration file. You should see that after this everything will be tilting in the same way.


#2 Building your own drones The next thing you should do is calibrate the accelerometer.

calibrate-the-accelerometer-Building-your-own-drones-5To 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.

#3 Next, set up the 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 the motor testing part you can manually test the motors individually turning on and off the voters.

#4 After this, set up the flight modes on your transmitter.

First, program the switches to a channel four of which are reserved. You begin from the fifth and sixth channels, which are auxiliary and here you should set up flight modes. After programming your switches, plug your battery, so your receiver will work. Then set the auxiliary first of your transmitter to the horizon and the auxiliary second to forward.

Review: Tattu 4 Port USB Wall Charger

There are millions of charging solutions out there. So we’ll never have a shortage of options. But often times we don’t have the charging solution we need until it’s too late. and we’re stuck sharing a charger with family members, or asking a stranger if you can borrow their charger because you left the house w/o a full charge. The best way to get ahead of this problem is to shop for the option that’ll work best for your situation.

Here’s a device that would be a good solution for the home, office or while traveling. This Tattu wall charger comes with a retractable prong that will plug into a standard Type A 110V outlet. Also being compact makes it perfect for traveling, without taking up too much space in your shoulder bag, or backpack.

1 2

The little black box comes equipped with a total of 4 USB charging ports. 2 of these ports allow for 1A output power, and the other 2 ports are 2.4A. So you have the option of 4 total ports for your various devices. It utilizes smart charging technology to detect the device you’ve connected, and will supply the power necessary to get you off that charger and on the go ASAP. The Tattu wall charger, is also designed with safety in mind, protecting against overheat, over current, over-voltage, and short circuiting.


Specs below for more detail:

  • AC Input: AC100V-240V (50-60Hz)
  • Output: DC 5V, 2.4Amax (2 ports) + DC 5V, 1Amax (2 ports)
  • Input Plug: Folding U.S plug
  • Continuous output power: Up to 34W
  • Dimension: 72.5mm x 48mm x 30.5mm (2.9in x 1.9in x 1.2in)

I’ve been using the Tattu wall charger in my office, at my desk for a few weeks now. It been very useful. I have my phones charging dock, my bluetooth headphones, and occasionally my smartwatch plugged into it, for a daily charging. It sits out of the way and unnoticeable , not adding to my already cluttered desk. I’ll continue to use it, knowing it’s safe to leave devices connected over the weekend, and happy that I’ve come back to the office on Monday to fully charged devices. I would recommend the Tattu 4 Port Wall Adapter to anyone with multiple devices.

Tattu 34W 4 Ports USB AC Adapter 6.8A Wall Charger – Review

Just over a week ago Tattu sent me a sample of their 4 port USB Wall Charger to test and review. During the week of test it I put it through the ringer. I tested with an android phone, iPhone, large power banks, small power banks, iPad, and a Windows 10 Asus Transformer Tablet. After the week of testing I have to say that I am impressed with the charging capabilities.

First Impressions:

4 port wall charger-packing

The package was sent from the Gensace & Tattu Online Store warehouse in California and arrived quickly and in a nicely packed mailer.

The 4 port USB wall charger came in a nice brown cardboard box with the Tattu logo and the product name on the front.

4 port wall charger-inner packing

After I opened the box up I found that the 4 port USB wall charger was nicely displayed and ready for you take it out of the box. I noticed it does not have any product paperwork or manual. Normally most products I receive for review or purchase come with at least a contact card with a QR code to the product page. I also noticed that the sample had dust, fingerprint smudges, and tiny surface scratches (only a couple of scratches on each side.) These issues could be resolved by adding a static plastic wrap around it and wearing gloves when packing the products in their boxes.

The charger is lightweight but feels like its made to last. Its size is perfect to put in a jacket pocket or a carry on bag.

4 port wall charger

The Tattu 34W 4 Ports USB AC Adapter 6.8A Wall Charger is the small port charger that comes in a shiny black plastic with a small blue LED light that lights up when the charger is under power. The plug has the smooth flip that locks it into position and keeps from folding back on itself.

The USB ports face down towards the floor and the charger is not adjustable. Your only option is to have your cords point towards the ground to charge.


4 port wall charger-charge

The first thing I tried to charge was my old LG G4. It takes about two hours to charge. But with fast charge devices it takes about an hour and half. With Tattu’s 4 USB wall charger it charged the phone from 10% to 100% in just over an hour and half. When I plugged in other devices. Everything charged faster but not as fast if I charging the devices on their own with the charger. I found the phones charged from 20% to 100% in an hour and forty-five minutes.

I charged my old Apple iPad 2nd Generation by itself. I started at 20% and charged to full. It took 2 hours and 20 minutes to charge and both the device and the charged stayed cool to the touch.

I charged my Asus Windows 10 Transformer Tablet starting with a 10% charge and charged it to full. It took 4 and half hours to charge. Both device and charger stayed cool to the touch. This tablet has always been a slow charge device. I normally use a more powerful charger to charge it. When I use it takes about 2 and half hours to charge.

When charging one device, both the charger and the phone stayed cool to the touch. When I charged multiple devices the charger was warm to the touch. Nothing to be concerned with. Most wall chargers get a little warm when charging multiple devices.

Charging Multiple Tablets at Same Time

4 port wall charger-charing

Next, I plugged in my LG G4 at 50% charge, iPad 2 at 4% charge, and my Asus Transformer Tablet with a 12% charge on the 4 port USB wall charger. The charger was warm to the touch. The devices had normal surface temperatures.

The LG G4 was fully charged in 40 minutes. The iPad and Asus tablet had only charged them another 10%.

It took about 4 hours to charge both tablets. I feel asleep about 3 hours in and before I had fallen asleep the tablets were over 80% charged.

AC Adapter 6.8A Wall Charger. This little charger makes a great travel charger and it will be added to my laptop bag. I spend a lot of time working in cafes and libraries and I often need to charge multiple devices at once. At most places I usually only have one or two outlets. So having the option to charge four devices at once works great for me.

Currently you can purchase this 4 port USB Wall Charger from the Gensace & Tattu Online Store or from Amazon. On both sites you will notice limited reviews and its because this device is about 3 months old as of the writing of this article. Currently you can pick up the charger for $13.99.

If you are looking for a 4 port USB wall charger to charge all your devices while traveling or just need an extra USB wall charger, this is a great option for you.

Does the Power Bank Damage Phone Battery?

The power bank is a daily life necessary for people, because of the phone battery is always lack of the power. Power bank also becomes our the extra phone battery. Some people are beginning to confuse that whether power bank will damage phone battery except for the natural decay of the phone battery? Does the power bank really damage your phone battery? Why?



As everyone knows, the bad power bank can damage the phone battery, why?

The Quality of PCB

Power bank is made up of the shell, battery cell and PCB, the most important is PCB. The quality of the PCB directly affects the device charge effect. Because the voltage drop or boost of power bank is controlled by PCB.

By the way, the safety protection is on the PCB, such as high temperature, overcharge, over-current, over-voltage, short circuit protection etc, these are essential for power bank, but for the bad PCB can’t provide better protection.


No trickle charge

As we know, The whole process of phone battery charging includes three stages: rapid charging, continuous charging, and trickle charging. The trickle charging is a small current to charge after the battery is full which can keep the electrons flowing and extend the battery life.
Most power banks have been disconnected from the phone before it enters the trickle charge, never charge fully.

How to avoid the phone battery damage?

First, Make sure the capacity of your power bank is higher than the capacity of your device. For instance, if the capacity of your phone is 2500mAh, then a power bank of capacity 2000mAh won’t be able to charge it fully from 0-100% whereas a power bank of 10000mAh capacity will be able to charge your phone from 0-100% a number of times.

Second, choose the well-known power bank, such as the Anker or Tattu 2in1 power bank. For the best power bank, the shell is strong enough to protect the internal components. Reasonable internal structure design to improve the cooling effect; The battery cell is durable and will not explode due to high temperature. The voltage of the PCB is stable and efficient, which affects the conversion rate. When you buy power bank online, you need to know, please check here

In addition, the regular manufacturers of power bank, there are more safety protections. So charging your phone with mobile power won’t damage the battery.


What Things to Bring When Traveling

As a travel enthusiasts, i always travel all over of our country with my friend. We love to take photos or make some videos during our journey. It feel very amazing to travel to somewhere you have never been.

As we all know, before we begin our journey, we need to prepare our baggage first, but sometimes you will forgot some necessary things or take some unnecessary things, it will take up the space of your luggage and you won’t use it.


Today I list somethings i will put in my luggage before traveling and hope it can help you have a good travel experience, if you have any other tips, please share it with me.

1. Backpack/Luggage/Travel bag. The backpack must suit for your body and feel comfortable when you use it, it’s better to choose the multifunction backpack, it’s very convenient to sort your luggage. If you travel to somewhere have flat road, it’s better to choose the luggage.
2. Cloth. Before your choose your cloth, you can check the weather first, and depend on how many days will you go. For example if it will rain, you can bring the lightweight raincoat, if it’s sunny day, you can take the sun protection clothing.
3. Some ID card: Passport/Credit card/Driver license/ID card. AND it’s better to take some copy of your cards, in case you lost your card but you need it instant.
4. Portable pillow, and ear plugs. It will help you to have a good relaxed in the bus or airplane.
5. The map and Traffic Equipment Map, in case you lost your way and phone is power off you can’t check it by your phone.
6. Some food like chocolate and Compress cookies, you can just put a little in your bag, in case you lost yourself in somewhere far from the city.
7. Essential medicine for example aspirin/Anti-diarrhea medicine/Band-aid.
8. A compact bag, you can put somethings (for example map/pen/water/phone/power bank) you will use when you out for sightseeing.
9. A charger/usb wire/power bank, as for me, i like to take photos and video with my friend, so i use my phone frequently, it will be very important to have the charger and or the power bank.

And today i want to share a goods with you, it really help me a lot! It’s a 2 in 1 wall charger power bank, you can find it at As before, I need to bring a charger, a wire and a power bank, it will be a little inconvenient to bring so many things just for my phone, and the power bank is too heavy for me, but now I get a new product: TATTU 2 IN 1 WALL CHARGER WITH 5200MAH POWER BANK.
