higher KV for a 4wd ZX-5?
I've been searching through the forum before asking, but I've found conflicting answers to my question.
I've found several posts offering the idea that a 2wd would work best with one motor, but a 4wd would work better with a higher kv motor. I had thought this would be the opposite, since a 4wd has more frictional inertia to overcome, therefor you wouldn't want to ask a higher kv motor to do more work. For example, I'll run an 8.5T in my sc10, and thought I'd get a 10.5T for my zx-5, but have been told I should run a 7.5T..
thoughts? Assuming the esc can handle it, does that motor/car combo make sense?

4wd buggies have tons of traction and therefor can use more motor. The drivetrain in a 4wd buggy isn't taxing a higher Kv motor as mush as you would think. 6.5 to 7.5 is the norm for 4wd buggy. A wheeler with a 10.5 honestly is kind of slow.
