Bro, Mamba Max can support 1/8, just depends how heavy & how big the wheels. I've done many tests. I've even ran it on Savage monster truck (on single ESC) without problems. If u check the internet, you should be able to find users with Mamba Max on 1/8 buggies & on-road also
Run sensibly, it's not strictly necessary to run 6S.
MMM is the pioneer (althouth a rough start with so many versions until V3 as of today), I like them all the way
but like Joeling mentioned... HPI BLUR (what a name
), Tekin & others also came out with their 1/8 capable brushless systems. They're all getting better & better.
Joeling has done many conversions. Only thing he didn't uploaded the photos yet
hehe. i know he has a lot done in his garage
