I had bought a great plane tutor kit and I want to know if I can use some stuff that I had before in this plane. I want to put in this plane a gws eps 400 f motor, gws 15a esc with bec, and I need to know what configuration of nimh batteries should I use for it? maybe a 8.4 2000mah?

PD: please forgive me if my english isn't better.
