Could anyone provide Y6 copter flight dynamics or principle?
Motion Equations ? and how to incorporate gyro and accelerometer feed back ?
i would like to make something like the image below, any suggestions what kind of propellers would be best ? ..

The basic principle is just like any other quad, hexa, or octo. You have the same number of motors turning in the clockwise direction as you do in the counter clockwise direction.
The main reason to do this is to nuetralize the torque on the craft coming from all the motors, so that you don't continually spin in one direction if the motor's are all at the same speed.
I think some of the flight dynamics of a quad are posted around somewhere here, if you can find that you can derive the specific maths for a Y6 with little difficulty.
But don't take my word for it, as the guy who designed and built it. He is here on DIYDrones, just like nearly anyone else you are ever likely to find in the hobbyist UAV community.
If I were building a shrediquette design, I would build it according to shrediquette's specifications first, before I started looking for different props. He details all the parts on his Webpage. I think that is the BOLT, and uses Airace propellers.
