Hey guys, do you want DIY quadcopter? DIY a quadcopter is a great thing, when you meet your friends, you introduce your quadcopter to your friends and proud to say that my friend, look here , I have made a plane. But in fact, if you want DIY a quadcopter is not easy, you must know many knowledge about quadcopter. Now I will tell you what you need if you plan to DIY a quadcopter.
Here’s what you’ll need:
- Electronic Speed Control (ESC)
- Flight Control Board
- Radio transmitter and receiver
- Battery Charger
- Power Distribution Board
- Bullet Connectors
- Servo Leads
Every quadcopter or other multirotor aircraft needs a frame to house all the other components. Things to consider here are weight, size, and materials. We recommend the DJI FlameWheel F450 or one of the many clones.
The motors have an obvious purpose: to spin the propellers. There are tons of motors on the market suitable for quadcopters, and usually you don’t want to get the absolute cheapest motors available, but you also don’t want to break the bank when some reasonably priced motors will suffice. Motors are rated by kilovolts, and the higher the kV rating, the faster the motor spins at a constant voltage.
Electronic Speed Controls
The electronic speed control, or ESC, is what tells the motors how fast to spin at any given time. ESC’s control the motors by varying the amount of current that is sent to them, these are a must for any RC vehicle using brushless motors. Don’t buy any that go bellow 25amp because they need to be able to take the high current that the battery is going to be putting out.
You can consider buy this flight controller；Hobbyking KK2.0 Multi-rotor LCD Flight Control Board. After scouring the Hobbyking website for more than a couple days I found this board. It comes jam packed right out of the box with all the software needed to fly the quad. Through this board it is also possible to calibrate all ESC’s within 30 seconds which i found most impressive since it saves a lot of tedious programming.
Radio Transmitter and Receiver
The radio transmitter and receiver allow you to control the quadcopter. There are many suitable models available, but you will need at least four channels for a basic quadcopter with the KK2.0 control board. We recommend using a radio with 8 channels, so there is more flexibility for later projects that may require more channels. The Turnigy 9x is a great choice for a first radio. It’s inexpensive yet still has some advanced functionality.
10 inch pros work well with the size of the Turnigy frame. They produce plenty of thrust combined with the motors above and they fit the prop adapters. Feel free to also buy these in different colors Stock up on plenty of these!
Quadcopters typically use LiPo batteries which come in a variety of sizes and configurations. We typically use 3S1P batteries, which indicates 3 cells in parallel. Each cell is 3.7 volts, so you can get a 11.1v lipo battery, of course you can buy a Tattu 11.1v lipo battery, too. LiPo batteries also have a C rating and a power rating in mAh (which stands for milliamps per hour). The C rating describes the rate at which power can be drawn from the battery, and the power rating describes how much power the battery can supply. Larger batteries weigh more so there is always a tradeoff between flight duration and total weight.
Most chargers will work with just about any type of battery so you kinda have free reign over choosing your own. I advise to choose balance charger for your battery, Charging LiPos is a complex process, because there are usually multiple cells within the battery that must be charged and discharged at the same rate.
Power Distribution Board
You can try to choose this: Hobby King Quadcopter Power Distribution Board.
I highly recomend getting one of these. It makes connecting your ESC’s to the battery simple and reduces the mess of wires you will have dangling around the Quadcopter
3.5mm Bullet Connectors, Its nice to be able to disassemble your quad if you have a malfunction or you accidentally make a wrong connection so use these to make all of your connections on the Quadcopter with the exception of the battery. Buy a couple sets at least because it will be nice to have some extras in the event that one comes off due to a bad soldering job.
Wire 16AWG,Its up to you if you think you’ll need it or not but it helped me out cause it meant I didn’t have to stretch the ESC’s as much on the frame. If you get some extra wire, purchase 1mtr of Red and Black (It helps differentiate + and -) plus its cheap.
You will absolutely need these (if you don’t already have any) to connect the receiver to the KK 2.0 Flight Controller.
These just some parts of a quadcopter, and if you want know more, You can contact me.
