Brushless setup for crawling

[Juju]

Hello,

I read your forum for several days. I leave in France so my English is not really perfect ;)

My Emaxx is a little bit Gorilla equiped :) and I use it for crawling over rocks and more. I'm not keen on bashing.

I want to know if I can use a brushless (9S for example) with standard 12 cells for crawling? My cells are not matched, no problem anymore?

The increase of speed is not too important compared to stock setup? Does a 9918 ESC provide a smooth control (like EVX)?

Thank you for reading
