Guys, Anybody having any info of functioning of Quadrotors.
I have seen a seperate cuircuit board along with receiver & speed controllers on all the quad rotors & if I am not wrong I think it is used for mixing/controlling all ESC's at one go etc.
Can some one throw light on this topic.

hi majraj currently i m working with the arduimu v2 flat imu which i m going to use as a main controller for my quadrotor.
read the hardware and the software part of this imu here on my blog
