Yes, you can (and must) use a separate ESC for each motor.

Making a single-board quad involves designing your own PCB and having it printed&cut. It takes a lot of work though, I'd recommend you to start by making a multiple-board quad first. It's easier to tweak that way.

A filter takes inputs from various unstable sensors (e.g. gyros, accs, barometers, ...) and produces stable state representations. For example it mixes individual angular accelerations from gyroscopes with vectors provided by accelerometers and magnetic sensors to deduce the 3D orientation of the vehicle, filtering out all the noise and inaccuracy inherent to the gyro.

thanx buddies ....
I learned about the dynamics of the quadrotor....
i mean its roll, pitch,yaw dynamics ..
i actually dono how to incorporate the equations to the quadrotor....

a gyro senses the angle rate rite?
if at all i wanna keep it stable i hve to use PID controller ...... am i rite so far?

for integrating the roll dynamics of the quad rotor....

guys if i wanna make it both autonomous and manual , wat should i hve to do ?

the programming of PID controller s oblivious to me ....... Does it easy for me to make a simple program ?
could anyone guide me ............


hoping for a fruitful response

i got confused in writing the transfer function
