Yeah Cain, the "Cirtix stock clubber" is NOT the 2.1 as I have received many emails about that today lol
This ESC is more of a sport ESC, I don't think it is designed for the likes of National racing (but I may be wrong)
I think this ESC is going to be better for things like VTA, F-1, RCGT, 12th Mini and things like that
