Feigao 9l warrior 7018 e-maxx

[Okta]

Hi guys first post!

Im am building up an e-maxx for some fun racing (just want to get it running on the track at this stage and learn to drive, not be ultra competative)

I have that motor/esc combo on its way and im wondering if anyone can tell me if it will work and how many cells i can run. I beleive the 7018 may be a bit underpowered but its what i have and i cant afford to change at the moment.
Will this esc be ok with a fan and small pinion or will it fry on 12 cells? (ib4200wc)

Thanks.
