Lehner Basic XL 1200 Brushless motor but which controller ?

Hi, I have a Revo Gorilla-maxx powered by an HV-Maxx, i'm French and running with this truck on the european tour (Monster Contest tour) and finished 4th last time.
But I also have an xb8 and the Team Helotes arena kit conversion and i'd like to brushless it !
So I want a very powerfull motor like the Lehner Basic XL 1200, but with its rpm, i want to know which controller is able to power it as well ?
I think i'll power it with 14 cells not more because it's heavy.

So can ou help me ?
Best regards.
