MPU6050 and Quadcopter

Hi,

Im currently using Arduino board with MPU6050 for controlling the quadcopter. The quadcopter is unbalance and when I check the value of yaw pitch raw angle when it is on the ground, the number is huge different from what Im expecting. I think I figure out the reason is that the vibration is the reason that cause the different in sensor reading. Is there anyone have experience in this ?

look here if you wish:
