Hi Chris,

I use the power expander and the reg. I use 2 x 5 cell nicads and have no problem. Batteries draw approx even. You have to check your servo,s and other electronic devices in the aircraft as this will determine wether you need a reg or not. In my case i run Futaba 9255 servos in my FB MB339, they do not like over 5.5 volts. If you are using say JR8511 then fully charged 5 cell pack say 6.9 volts approx is ok. Hope this helps
