KB 45mm Motor Info

[lincpimp]

Just purchased an 8xl and 10xl from UH. Was wondering what kind of amp draw I can expect. Will run the 8xl on 4 or 5s and the 10xl on 6s, maybe 5s. They will be used in an aftershock, with an emaxx tranny, and stock tires, geared for 40-45mph. I figured that I would need at least a 6000mah 20c battery. Not sure If that would be ok since there is very little info on these motors. Not sure if they will perform similar to the feigao xl cans?!?!?!
