What would this combo do in a Hyper 7?

[SKiTZ]

An 8000mah Lipo sounds ok. What voltage? What motor would give me what I want? I really want to use the Quark Monster. I like its features. I don't want to have any problems. If I have to spend a little more to get a better product then I will. I also know nothing about buying Lipos or maintaining them. But I will ask those questions another time. I don't want to loose focus. So............ 8000mah....... Quark Monster........ Now, motor and gearing.
