I use the phoenix 45 with the servos you have and don't use any other battery's at all and mine works fine.You just get your Voyager E.Man I really like mine and it flys great when you get it all set up.The only difference between mine and yours is I use the Astro Flight 20 motor.Have you seen the stretched Voyager E I am thinking about doing it to mine you can use the 475 blades with the stretched version.
