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...

Yep, disable the internal bec and run a ccbec, or receiver pack. Some have issues with fully charged 6s packs making the esc "freak out" until the voltage drops slightly. I did not notice this with my 6s buggy. I would not gear too high either, 40mph sounds good to me and I gear mostly everything to that speed.

I ran a Quark 80B on 5s in a 1/8 buggy and pushed it over 60mph. The little quarkk actually held up fine. If you gear it down a bit in the truggy I bet that 80B might surprise you. Just make sure you have it mounted flat to the aluminum chassis to act as a heat sink or attach some sort of heat sink and fan to it.
