got my motor and esc mounted up today and found a prob, the stock metal spur does not mesh well with 32p pinions, it works if you kick the motor out a bit, but its noisy running lol, any replacmenbt spurs or anyone know of pinions that will work 5mm bore of course thanks in advance

About a 15 or 16T would get you where you want to be. I'd go with the 15T if it were my vehicle.

4S is nominal 14.8V, it's only 16.8V directly off the charger. Under any moderate load at all, it'll drop down near 14.8V.

Best off to order a few around the size you want. Will you be racing with it on a track or bashing with it?
