I have been reading the threads
I want to know how to decide which type of flight controller to use nd do we need to code it from pc or its already been coded
And i will be making own frame using aluminum or fiber glass or carbon sheets listed by many people

Kk2.1 comes pre programmed, check YouTube

Is it the best tht fits my budget and any other details for it

The kk 2.1 is widely considered the best beginner's flight control board. It has an on board LCD screen for easy setup. It has relatively limited functionality e.g. no GPS but at it's price - 2100 in India, it is an excellent option for a beginner. The MultiWii board has been also suggested since you can add features like GPS later but it does not have a screen. For the transmitter, I would recommend one of these: Avionic RCB6i (Rs. 3000), FlySky FS-T6 (Rs. 3900), FlySky TH-9x (Rs. 5050), Turnigy 9X/9Xr/9XR pro (Rs. 7200-10000)

Ohk
If i want to add gps for later so which board i should consider if i get successful for this i can use the same as my be final year project by just adding few new things on it

The problem is that your budget is 6-7k. An APM 2.6 flight control board with a GPS module itself will cost around 6k. So that does not leave any money for the actual quadcopter. I suggest you start with a kk 2.1 and buy an APM later. Otherwise, PM sooraj.palakkad. He helped in building my quad and he also completed a quad with a DIY MultiWii board so you should ask him about MultiWii. I really don't know much about the Multiwii/ Crius boards.

Ohk i will ty for the help

You can use multiwii boards for gps if you want to.

Multiwio boards can u tell me more abt it

Hi, cool16yash , Received your PM, I am posting answer to your queries here, because, other people can also benefit .

Well Before, going to make your own flight control board, shall i know your skills,
I assume you have basic knowledge in electronics
Do you have experience with arduino or any other microprocessor platforms ?

Multiwii, is a very good open source flight controller Coded on Arduino platform. At first, it was intended to help people who want to make cheap Flight controllers from Arduino boards and motion sensors from Wii, nunchuck controllers. Later, many people developed the source code to include many advanced features and support for different h/w.

You can make a simple flight controller with self level feature (Like KK2), for 500 to 1000 Rs, using Arduino and a sensor break out board (MPU6050 or other supported sensors) On multiwii platform.
Later you can add advanced features too.

Right now i am in te so only basic knowledge i got as u said i am new to rc so dont know abt it
So decided to make one so i get much info at it as my budget is less i throughout of making own things tht me help me learn nd also i will get properly merged into it
So now the question how do i develop my own flight controller
Can u help me out with the details

Making your own flight controller is quite challenging, especially if you are new to RC. It will be much quicker and more convenient to buy one.  But if you have experience with microcontrollers and electronics and you want a challenge, you could definitely succeed. There are several flight controllers you could make such as the Aeroquad and MultiWii. Check their websites.
Basically, you would need a base microcontroller- such as an Arduino/ clone. You would then need to add sensors such as a gyro/ accelerometer or integrated IMU module. You would also need to download firmware or develop your own (quite difficult)

Well, it's not that hard.

But I have another option for him - Can arrange parts like motors + ESC + KK2.1 + othe connectors and cables for around 5500 to 6000.
He can  get a LiPo + Radio + charger for the remaining money.

That's a great price. How are you arranging it?

Ohk cool ty for the help guys
I hope my first quadcoper goes well nd hope i enjoy making rc

Please don't post with SMS language, I get what you mean by "ty", only now - Please use full words and sentences.

Ohk i will use full words

That helps.

finally i have recieved my all the parts for building a quadcopter and now i want help in understanding them and the way to make the connections and all as said by sooraj i am going on making flight controller using arduino nano with mpu 6050 so i need more details about the coonection of esc motors battery and other stuff to it

can any one help me with the power connections to the quadcopter
do i need to connect each servo to gnd and vcc??

Bump

servo? did you mean ESC?


read here: http://www.multiwii.com/connecting-elements
this shows the pinout for arduino promini and the pin numbers are almost same for arduino nano too.

Ohk thankyou

Yeah the esc connection i am not getting it properly
