I am making a quadracopter using Arduino, gyro and accelerometer, 1000kv motor with 30A esc. While writing the program for flight control I am doubtful of the value to be used for 'I' controller in PID algorithm. I tried to set the value between 1.0 to 1.5 but the copter would drift apart to much. I have set Maximum PID output to 400.

It is about stabilizing closed loop control system. Either you can tune the gain with trial and error method or do a theoretical analysis of system. I would suggest you refer manual for a range of values and then try to find suitable value with trail and error method. By the way this question doesn't suit SO.
