Anybody has a good guess for the electrical load on a 4.8V, 4cell, 500mAh reciever battery pack? 4 standard servos (S3004) and 1 heavy duty (s3305). All servos are not digital and go in an GP Extra 300-.60, 9 1/2lbs, Saito 1.20.

What is the minimum voltage/cell that is considered safe when flying?

Thanks
