Sensored motor can cause cogging if the batteries arnt up to snuff, but i wouldnt worry about it. also the esc that comes with that rtr can only handle a 10.5 turn or less i have a 9 turn which is a little crazy for the track but i can program my power deliver , amount of power to get it where i want it. Tex is right less is more on the track sometimes.
