Quark 80b or MM?

[Thunderbruiser]

Ok so i was in the garage doing a little clean-up and i've found a quark 80b that i purchased some time last year...would this be better in the truggy or should i stick with the mm esc? i ask because then i could put my mamba back on my rustler...also could this run 4/5s power easily?

i need suggestions quick as possible thanks guys
