I realy considere a Neu 1509 in the 2700 Kv.

But tell me please, which is better on 3s: a lower Kv motor with a bigger pinion or an higher Kv motor with a smaller pinion

Or both is as good?

Depends. Either way, you want some options for gearing. If you start off at the max or min gearing possibility, you don't have any room to go further.

Generally, on the good motors, I kinda like getting a faster spinning setup and gearing down. Since each motor revolution is moving the vehicle less (and doing less work), the ESC seems to have an easier time locating rotor position at slow speeds.
