Whoa!
I read of a system to eliminate the vibrations of a helicopter for aerial photography, but its working is a tightly kept secret.

Its not a big deal Kunal, u just put a gyro + position sensor in x and y planes, gyro's give u acceleration while position sensors give u distance, then u can deduce few equations and a simple control system would solve the problem, I'm just looking for references to save me development time.</b?
Thanx
