What Frecklychimp says is correct. 12 months back, 550 sized motors really only came in 1/8th systems, with low kV's designed for 4S use. All the SCRT10's and Hyper 10SC's I've seen were set up then.
Now there are several 550's designed specifically for SCT's, which can be run with any high rated 1/10th esc. The Mamba Max Pro you've ordered should be up to this.
Running a bigger motor with more torque will reduce the strain of the motor of turning those heavy 1/8th diffs, and in turn that means less current for the esc and battery to have to handle.
