Quadrotor with Arduino Mega and IMU

Hi everyone,

I'm doing a project for flight control software of quadrotor(pc control). And i did motor speed control with arduino mega. For balance of quadrotor, i ordered an IMU but i don't know how i will use it. In addition to this, i don't know about pid controller. Can i do this project without pid controller? Do you know about this topic any source, web site, article..(especially software)? What i should pay attention for balanced flying?

Thanks for your interest..

Have you tried Google Code Archive - Long-term storage for Google Code Project Hosting. ?

Thanks, but i studied arducopter. It is too different and designed for 9 channels remote control. As well as, its pid settings are automatic.
