Revo - 4s 9XL

Arct1k, could you tell me please your diff setup?? do you run the stock diff or you've put Maximizer diff cup, or the RcMonster hybrid? And for the tranny, have you lock it in second or keep the 2 speed intact?

Only problem, i'am not able to decided between the 8XL and the 9XL. I'll run it on Flightpower 4s, 5000 mAh.

I'am to build my e-revo and want to know.

Thank
