I guess the 1300 would run more efficiently and will probably fit better the pinion range I have because it will go up to around 29000 rpm while the 1500 will fly up to 33000 so it may need more range in the smaller pinions (stock is 16). Iīd better choose the 1300 one, wouldnīt I?
Thanks.

IMO 29,000 is a bit low, I would go with the 1500kv option, and when you gear up the motor will lose effiency since you are increasing the motors work load, and it sounds like you will be in a racing application so you might want a little quickness when you gear up too much you lose that to a certain point, I am a basher so that quickness isnt that important I shoot for the 40,000 rpm range for my Revo. My Neus kv is 1650 on 6s and I like it. Most guys who race buggys run a 2200 kv with 4s and get good results...remember a 5 or 6s battery is pretty heavy and could mess with the balance of the buggy
