Quark 80b or MM?

[Thunderbruiser]

well i'd rather use 5s or 6s if i could because im just that greedy however i wanna make sure the esc could handle it ya know...also if i run 5s/6s do i need to run an rx pack and disable the internal bec?

i'd rather run this because it's spec'd higher and that way i'd have a mamba for the rustler...and 1 mamba left that i have to have fixed...
